[Radiologic practice and radioprotection in Italian hemodynamic laboratories].  

PubMed

Increasing numbers of diagnostic and therapeutic cardiac catheterization procedures are performed in Italy each year. Radiation exposure of the cardiac catheterization laboratory staff is a known hazard, and there is growing public and professional concern over the risks of low-energy medical ionizing radiation for the patients. The aim of this study was to outline the range of current radiological and radiation protection practice in large-volume cardiac catheterization laboratories in Italy. In August 1994 a questionnaire was submitted to the chief invasive cardiologist of the 32 cardiac catheterization laboratories nation-wide having performed at least 1000 procedures in 1993. All laboratories responded. There were variations in both the radiologic technique (cine framing speed, mean film lengths and fluoroscopy times) and the radiation protection practice (use of shields, leaded collars and glasses, and sites where dosimeters are worn). In 22 of 32 laboratories the cardiologists were not aware of radiation exposure data, and only 6 laboratories could quote the exposure provided by their X-ray system or estimates of the dose absorbed by patients during diagnostic or therapeutic procedures. The results of this survey indicate that radiological practice, and techniques for measuring and reducing exposure of the personnel vary widely in cardiac catheterization laboratories in Italy. These data suggest also that reducing patients' radiation exposure is not, in general, considered to be a quality assurance priority by interventional cardiologists. PMID:8697469

Exploratory Study of Radiology Coding in Health Information Management Practice  

PubMed Central

An exploratory study was undertaken to determine the role and practice issues of radiology coding in health information management (HIM) practice. The study sought to identify the challenges of radiology coding and the solutions implemented to address these challenges. A self-report survey was sent to 828 American Health Information Management Association (AHIMA) members identified as directors, managers, or supervisors of HIM departments and/or coding. Two hundred seventy-eight surveys were used for data analysis purposes. Sites reported that on average they have 3.4 coders devoted to radiology coding who code an average of 4,245 reports per month. Productivity standards varied by exam type ranging from 7 (interventional radiology) to 31 (diagnostic) exams coded per hour. Diagnosis codes were assigned most frequently for diagnostic, ultrasound/nuclear, MRI/CT, and mammography exams, while diagnosis and procedural codes were assigned more frequently for interventional radiology exams. The need for education specifically focused on interventional radiology coding was identified along with other issues affecting the quality of radiology coding. Suggested solutions to challenges of radiology coding such as establishing a good working relationship with physicians, radiology, and charge description master (CDM) departments were suggested.

Radiological risk guidelines for nonreactor nuclear facilities at the Pacific Northwest Laboratory  

SciTech Connect

Radiological risk evaluation guidelines for the public and workers have been developed at the Pacific Northwest Laboratory (PNL) based upon the Nuclear Safety Policy of the US Department of Energy (DOE) established in Secretary of Energy Notice SEN-35-91. The DOE nuclear safety policy states that the general public shall be protected such that no individual bears significant additional risk to health and safety from the operation of a DOE nuclear facility above the risks to which members of the general population are normally exposed. The radiological risk evaluation guidelines developed at PNL are unique in that they are (1) based upon quantitative risk goals and (2) provide a consistent level of risk management. These guidelines are used to evaluate the risk from radiological accidents that may occur during research and development activities at PNL, and are not intended for evaluation of routine exposures. A safety analyst uses the,frequency of the potential accident and the radiological dose to a given receptor to determine if the accident consequences meet the objectives of the Nuclear Safety Policy. The radiological risk evaluation guidelines are an effective tool for assisting in the management of risk at DOE nonreactor nuclear facilities. These guidelines (1) meet the nuclear safety policy of DOE, (2) establish a tool for managing risk at a consistent level within the defined constraints, and (3) set risk at an appropriate level, as compared with other risks encountered by the public and worker. Table S.1 summarizes the guidelines developed in this report.

ORNL necessary and sufficient standards for environment, safety, and health. Final report of the Identification Team for other industrial, radiological, and non-radiological hazard facilities  

SciTech Connect

This Necessary and Sufficient (N and S) set of standards is for Other Industrial, Radiological, and Non-Radiological Hazard Facilities at Oak Ridge National Laboratory (ORNL). These facility classifications are based on a laboratory-wide approach to classify facilities by hazard category. An analysis of the hazards associated with the facilities at ORNL was conducted in 1993. To identify standards appropriate for these Other Industrial, Radiological, and Non-Radiological Hazard Facilities, the activities conducted in these facilities were assessed, and the hazards associated with the activities were identified. A preliminary hazards list was distributed to all ORNL organizations. The hazards identified in prior hazard analyses are contained in the list, and a category of other was provided in each general hazard area. A workshop to assist organizations in properly completing the list was held. Completed hazard screening lists were compiled for each ORNL division, and a master list was compiled for all Other Industrial, Radiological Hazard, and Non-Radiological facilities and activities. The master list was compared against the results of prior hazard analyses by research and development and environment, safety, and health personnel to ensure completeness. This list, which served as a basis for identifying applicable environment, safety, and health standards, appears in Appendix A.

Surface radiological investigation of Trench 5 in Waste Area Grouping 7 at Oak Ridge National Laboratory, Oak Ridge, Tennessee  

SciTech Connect

A surface radiological investigation of areas encompassing Trench 5 on the Oak Ridge Reservation (ORR) was conducted from May 1990 through November 1990. This survey was led by the author, assisted by various members of the Measurement Applications and Development (MAD) group of the Health and Safety Research Division (HASRD) of Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. The purpose of the investigation was to determine the presence, nature, and extent of surface radiological contamination at Trench 5, the Homogeneous Reactor Experiment fuel wells, and surrounding areas. Based on the data obtained in the field, interim corrective measures were recommended to limit human exposure to radioactivity and to minimize insult to the environment. It should be stressed that this project was not intended to be a complete site characterization but rather to be a preliminary investigation into the potential contamination problem that might exist as a result of past operations at Trench 5.

The efficacy for radiological decontamination of the laboratory standard fume hood as constructed of stainless steel, compared to that of powder-coated carbon steel is described. While the chemical inertness of powder-coated surfaces is good, faced with everyday abrasion, aggressive inorganic solutions and vapors, and penetrating organics commonly employed in government laboratory fume hoods, radiological decontamination of powder-coated steel surfaces was found to be similar to those made of stainless steel for easily solubilized or digestible radionuclides. Plutonium was difficult to remove from stainless steel and powder-coated surfaces, especially after prolonged contact times. PMID:22739967

A Useful Formula for the Radiological Calibration Laboratory  

SciTech Connect

A useful technique for determining the relationships between irradiation position and air kerma or neutron dose equivalent rate is presented. The standard geometric model (1/r2) is expanded allowing the user to include curvature in the model caused by scattered radiation. This technique applies to clean irradiation geometries that are well modeled by the standard geometric model, high-scatter geometries encountered in well irradiators, and neutron irradiation fields used to calibrate health physics instruments and personnel dosimeters. The technique, with slight modification, is also useful for determining the quality of x-ray beams. The basic equations and the implementing Excel functions are listed. In addition, several examples are presented to demonstrate the application of the technique.

Quality assurance program for field health laboratories  

SciTech Connect

The Federal Mine Safety and Health Act of 1977 (and previously the Federal Coal Mine Health and Safety Act of 1969) established mandatory dust standards for coal mines. Title II requires the Secretary of Labor to make frequent inspections of coal mines to determine compliance with the mandated 2.0 mg/m/sup 3/ respirable dust standard. Such inspections are made by representatives of the Secretary, who are coal mine inspectors of the Mine Safety and Health Administration (MSHA). Sampling equipment used to assess respirable dust concentrations is calibrated and maintained at local field laboratories located in each Coal Mine Safety and Health district. Samples collected during inspections are weighed and analyzed at these laboratories. A selected number of laboratories are also qualified to weigh operator samples in accordance with provisions promulgated in Title 30, Code of Federal Regulations, Part 70. This paper describes the quality assurance program conducted to assure the performance integrity of the field laboratories in the maintenance and calibration of respirable dust sampling equipment and the weighing of respirable coal mine dust samples. 18 figs.

Radiological survey support activities for the decommissioning of the Ames Laboratory Research Reactor Facility, Ames, Iowa  

SciTech Connect

At the request of the Engineering Support Division of the US Department of Energy-Chicago Operations Office and in accordance with the programmatic overview/certification responsibilities of the Department of Energy Environmental and Safety Engineering Division, the Argonne National Laboratory Radiological Survey Group conducted a series of radiological measurements and tests at the Ames Laboratory Research Reactor located in Ames, Iowa. These measurements and tests were conducted during 1980 and 1981 while the reactor building was being decontaminated and decommissioned for the purpose of returning the building to general use. The results of these evaluations are included in this report. Although the surface contamination within the reactor building could presumably be reduced to negligible levels, the potential for airborne contamination from tritiated water vapor remains. This vapor emmanates from contamination within the concrete of the building and should be monitored until such time as it is reduced to background levels. 2 references, 8 figures, 6 tables.

Overview of Sandia National Laboratories and Khlopin Radium Institute collaborative radiological accident consequence analysis efforts  

SciTech Connect

In January, 1995 a collaborative effort to improve radiological consequence analysis methods and tools was initiated between the V.G. Khlopin Institute (KRI) and Sandia National Laboratories (SNL). The purpose of the collaborative effort was to transfer SNL`s consequence analysis methods to KRI and identify opportunities for collaborative efforts to solve mutual problems relating to the safety of radiochemical facilities. A second purpose was to improve SNL`s consequence analysis methods by incorporating the radiological accident field experience of KRI scientists (e.g. the Chernobyl and Kyshtym accidents). The initial collaborative effort focused on the identification of: safety criteria that radiochemical facilities in Russia must meet; analyses/measures required to demonstrate that safety criteria have been met; and data required to complete the analyses/measures identified to demonstrate the safety basis of a facility.

Pacific Northwest National Laboratory Potential Impact Categories for Radiological Air Emission Monitoring  

SciTech Connect

In 2002, the EPA amended 40 CFR 61 Subpart H and 40 CFR 61 Appendix B Method 114 to include requirements from ANSI/HPS N13.1-1999 Sampling and Monitoring Releases of Airborne Radioactive Substances from the Stack and Ducts of Nuclear Facilities for major emission points. Additionally, the WDOH amended the Washington Administrative Code (WAC) 246-247 Radiation protection-air emissions to include ANSI/HPS N13.1-1999 requirements for major and minor emission points when new permitting actions are approved. A result of the amended regulations is the requirement to prepare a written technical basis for the radiological air emission sampling and monitoring program. A key component of the technical basis is the Potential Impact Category (PIC) assigned to an emission point. This paper discusses the PIC assignments for the Pacific Northwest National Laboratory (PNNL) Integrated Laboratory emission units; this revision includes five PIC categories.

Public health laboratory systems development in East Africa through training in laboratory management and field epidemiology  

PubMed Central

Laboratories are integral to the delivery of quality health care and for public health functions; however laboratory systems and services are often neglected in resource-poor settings such as the East African region. In order to sustainably strengthen national laboratory systems in resource-poor countries, there is a need to train laboratory personnel to work in clinical as well as public health laboratories. In 2004,Kenya, Uganda, Tanzania, and South Sudan began training public health laboratory workers jointly with field epidemiologists in the Kenya Field Epidemiology and Laboratory Training Program (FELTP), and later through the Tanzania FELTP, as a strategy to strengthen public health laboratories. These programs train laboratory epidemiologists through a two-year public health leadership development course, and also offer various types of short course training for frontline staff. The FELTP laboratory graduates in Kenya, Tanzania, Uganda, and South Sudan are working in their respective countries to strengthen public health laboratory systems while the short course participants provide a pool of frontline implementers with the capacity to support the lower tiers of health systems, as well as serve as surge capacity for the regions and the national level. Through training competent public health laboratory workers, the East African ministries of health, in collaboration with other regional partners and stakeholders are now engaged in developing and implementing a holistic approach that will guarantee an overall strengthening of the health system by using well-trained public health laboratory leaders to drive the process. Strengthening public health laboratory medicine in East Africa is critical to improve health-care systems. The experience with the FELTP model in East Africa is a step in the right direction towards ensuring a stronger role for the laboratory in public health.

Idaho National Engineering and Environmental Laboratory radiological control performance indicator report. First quarter -- calendar year 1998  

SciTech Connect

This document provides a report and an analysis of the Radiological Control Performance Indicators through the first Quarter of Calendar Year 1998 (CH-98) for Lockheed Martin Idaho Technologies Company (LMITCO). LMITCO is the prime contractor at the Idaho National Engineering and Environmental Laboratory (INEEL). This Performance Indicator Report is provided in accordance with Article 133 of the INEEL Radiological Control Manual. These indicators should be used by management as tools to focus priorities, attention, and adherence to As-Low-As-Reasonably-Achievable (ALARA) practices. The INEEL collective occupational radiation deep dose is 12.426 person-rem year to date, compared to a quarterly goal of 16.2 person-rem. In comparison to last year, the site dose goal has been reduced mainly due to work scope reductions at the Idaho Nuclear Technologies and Engineering Center (INTEC), formerly the Idaho Chemical Processing Plant. Due to unforeseen increases in shipments to the Radioactive Waste Management Complex, the authors anticipate additional dose increases and will reflect these changes in the next quarter report.

Surface radiological investigation of Trench 5 in Waste Area Grouping 7 at Oak Ridge National Laboratory, Oak Ridge, Tennessee. Environmental Restoration Program  

SciTech Connect

A surface radiological investigation of areas encompassing Trench 5 on the Oak Ridge Reservation (ORR) was conducted from May 1990 through November 1990. This survey was led by the author, assisted by various members of the Measurement Applications and Development (MAD) group of the Health and Safety Research Division (HASRD) of Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. The purpose of the investigation was to determine the presence, nature, and extent of surface radiological contamination at Trench 5, the Homogeneous Reactor Experiment fuel wells, and surrounding areas. Based on the data obtained in the field, interim corrective measures were recommended to limit human exposure to radioactivity and to minimize insult to the environment. It should be stressed that this project was not intended to be a complete site characterization but rather to be a preliminary investigation into the potential contamination problem that might exist as a result of past operations at Trench 5.

An In Situ Radiological Survey of Three Canyons at the Los Alamos National Laboratory  

SciTech Connect

An in situ radiological survey of Mortandad, Ten Site, and DP Canyons at the Los Alamos National Laboratory was conducted during August 19-30, 1996. The purpose of this survey was to measure the quantities of radionuclides that remain in the canyons from past laboratory operations. A total of 65 in situ measurements were conducted using high-resolution gamma radiation detectors at 1 meter above the ground. The measurements were obtained in the streambeds of the canyons beginning near the water-release points at the laboratories and extending to the ends of the canyons. Three man-made gamma-emitting radionuclides were detected in the canyons: americium-241 ({sup 241}Am), cesium-137 ({sup 137}Cs), and cobalt-60 ({sup 60}Co). Estimated contamination levels ranged from 13.3-290.4 picocuries per gram (pCi/g)for {sup 241}Am, 4.4-327.8 pCi/g for {sup 137}Cs, and 0.4-2.6 pCi/g for {sup 60}Co.

Medical response to a major radiologic emergency: a primer for medical and public health practitioners.  

PubMed

There are several types of serious nuclear or radiologic emergencies that would require a specialized medical response. Four scenarios of great public health, economic, and psychologic impact are the detonation of a nuclear weapon, the meltdown of a nuclear reactor, the explosion of a large radiologic dispersal device ("dirty bomb"), or the surreptitious placement of a radiation exposure device in a public area of high population density. With any of these, medical facilities that remain functional may have to deal with large numbers of ill, wounded, and probably contaminated people. Special care and/or handling will be needed for those with trauma, blast injuries, or thermal burns as well as significant radiation exposures or contamination. In addition, radiologists, nuclear medicine specialists, and radiation oncologists will be called on to perform a number of diverse and critically important tasks, including advising political and public health leaders, interfacing with the media, managing essential resources, and, of course, providing medical care. This article describes the medical responses needed following a radiologic or nuclear incident, including the symptoms of and specific treatments for acute radiation syndrome and other early health effects.

Radiological False Positives in Environmental Soil and Groundwater Data from Commercial Laboratories  

SciTech Connect

Laboratory identification of radionuclides at environmental concentrations can easily be mistaken, because many energy interferences (coincident or overlapping spectral peaks) are possible. Conventional laboratory quality control measurements are typically not designed to test interferences found in real samples. In order to evaluate the occurrence of radiological false positives in environmental soil and groundwater samples collected at the Savannah River Site, instrument printouts, calibration records, and procedure manuals were examined between 1997 and 2001 at five commercial radiological laboratories. False positives of many radionuclides were found to be routinely reported at all five laboratories; causes vary. Magnitudes were generally between 0.1 and 3 pCi/g in soils, and between 2 and 40 pCi/L in groundwater, within the range of possible concern to regulators. The frequency of false positives varied, but for several nuclides listed below, nearly every detection reported in SRS environmental samples during the study period was judged to be false. Gamma spectroscopy: Low-level false positives of Mn-54, Zr-95, Eu-155, and Np-239 were reported in many soil samples from four laboratories, due to interference from naturally occurring Tl-208, Pb-212, and Ac-228. There were two causes. First, laboratories did not include low abundance (less than 2 per cent) peaks of Tl-208, Pb-212, and Ac-228 in the libraries used by instrument software for interference correction. Second, even when instrument software rejected the identifications, incorrectly identified nuclides were still often reported as detected, because some labs' data management systems were not able to distinguish between software-accepted nuclides and software-rejected nuclides. Magnitudes of these false positives are usually below 1 pCi/g. Alpha spectroscopy: Incomplete chemical separation and breakthrough of natural radionuclides and/or daughters of laboratory tracers generate false positives in soils up to about 5 pCi/g. Examples include natural Th-228 causing false positives of Am-241 and Pu-238; natural U-234 being mistaken for Np-237; and natural Ra-224 generating false positives of Cm-243/244. Peak taildown of tracers or other nuclides into neighboring peak windows can also generate false positives in both soils and groundwater. Examples include taildown of Th-229 tracer into the Th-230 spectral window, and U-234 taildown causing false positives of U-235. Liquid Scintillation: Incomplete chemical separation may generate false positives of virtually any Liquid Scintillation nuclide. High tritium content in Savannah River Site groundwater causes false positives of C-14. Actinides produce false positives of Pm-147. Most false positives in alpha spectroscopy and liquid scintillation counting at commercial labs are due to incomplete separation of the target nuclide from interferors. However, quality control measurements such as matrix spikes and chemical yield are of ten unable to identify cases where interfering nuclides break through into the final preparation. In addition, laboratory personnel often fail to manually interpret sample spectra, and thus do not notice peak interference when it occurs. In fact, some laboratories are unable to produce energy spectra for liquid scintillation or alpha spectroscopy, making recognition of peak interference virtually impossible. Gamma spectroscopy of environmental samples usually does not involve chemical separation, so peak interference may occur in every sample. Interference correction software appears to be ineffective at the concentrations seen in environmental samples. At all labs, careful manual review of printouts appeared to be lacking when the study was performed. Some labs have improved their data review processes since then.

Results of the independent radiological verification survey of the remedial action performed at the former Alba Craft Laboratory site, Oxford, Ohio, (OXO001)  

SciTech Connect

Between October 1952 and February 1957, National Lead of Ohio (NLO), a primary contractor for the Atomic Energy Commission (AEC), subcontracted certain uranium machining operations to Alba Craft Laboratory, Incorporated, located at 10-14 West Rose Avenue, Oxford, Ohio. In 1992, personnel from Oak Ridge National Laboratory (ORNL) confirmed the presence of residual radioactive materials from the AEC-related operations in and around the facility in amounts exceeding the applicable Department of Energy (DOE) guidelines. Although the amount of uranium found on the property posed little health hazard if left undisturbed, the levels were sufficient to require remediation to bring radiological conditions into compliance with current guidelines, thus ensuring that the public and the environment are protected. A team from ORNL conducted a radiological verification survey of the former Alba Craft Laboratory property between December 1994 and February 1995. The survey was conducted at the request of DOE and included directly measured radiation levels, the collection and analysis of soil samples to determine concentrations of uranium and certain other radionuclides, and comparison of these data to the guidelines. This document reports the findings of this survey. The results of the independent verification survey of the former Alba Craft Laboratory property demonstrate that all contaminated areas have been remediated to radionuclide concentrations and activity levels below the applicable guideline limits set by DOE.

Health implications of radiological terrorism: Perspectives from Israel  

PubMed Central

September 11th events taught us, members of the medical community, that we need to prepared for the worst. Nuclear terror is no longer science fiction. Radiological weapons of mass terror come in three flavors: The first one is nuclear. Since 1992, there have been six known cases of highly enriched uranium or plutonium being intercepted by authorities as it passed in or out of the former Soviet Union. Constructing a nuclear fission weapon requires high-level expertise, substantial facilities, and lots of money. All three of which would be difficult, although not impossible, for a terrorist group to pull off without state support. However, terrorists could carry out potential mass destruction without sophisticated weaponry by targeting nuclear facilities using conventional bombs or hijacked aircrafts. Terror attacks could also carry out mass panic and radioactive contamination of people and environment by dispersal of radioactive materials with or without the use of conventional explosive devices. Most medical and para-medical personnel are not familiar with CBRN terror and radiation casualties. To lessen the impact of those potential attacks and provide care for the greatest number of potential survivors, the community as a whole – and the medical community in particular – must acquire the knowledge of the various signs and symptoms of exposure to irradiation and radioactive contamination as well as have a planned response once such an attack has occurred. Based on knowledge of radiation hazards, medical emergency planers should analyze the risks of each scenario, offer feasible solutions and translate them into internationally accepted plans that would be simple to carry out once such an attack took place. The planned response should be questioned and tested by drills. Those drills should check the triage, evacuation routes, decontamination posts, evacuation centers and receiving hospitals. It is crucial that the drill will consist of simulated casualties that will follow the evacuation route from point zero to the ED. Knowledge and exercise will reduce terror (fear) from radiation and help the community as a whole better cope with such an event. This article will review the general information of radiation types, their biological damage, clinical appearance and general concepts of nuclear event planning, focusing on medical response and focus on the Israeli perspective.

Perspectives of public health laboratories in emerging infectious diseases  

PubMed Central

The world has experienced an increased incidence and transboundary spread of emerging infectious diseases over the last four decades. We divided emerging infectious diseases into four categories, with subcategories in categories 1 and 4. The categorization was based on the nature and characteristics of pathogens or infectious agents causing the emerging infections, which are directly related to the mechanisms and patterns of infectious disease emergence. The factors or combinations of factors contributing to the emergence of these pathogens vary within each category. We also classified public health laboratories into three types based on function, namely, research, reference and analytical diagnostic laboratories, with the last category being subclassified into primary (community-based) public health and clinical (medical) analytical diagnostic laboratories. The frontline/leading and/or supportive roles to be adopted by each type of public health laboratory for optimal performance to establish the correct etiological agents causing the diseases or outbreaks vary with respect to each category of emerging infectious diseases. We emphasize the need, especially for an outbreak investigation, to establish a harmonized and coordinated national public health laboratory system that integrates different categories of public health laboratories within a country and that is closely linked to the national public health delivery system and regional and international high-end laboratories.

Strengthening national laboratory health systems in the Caribbean Region.  

PubMed

The President's Emergency Plan for AIDS Relief (PEPFAR) programme for the Caribbean Region was established in 2008 to address health system challenges, including fragile laboratory services and systems. The laboratory component of this programme consisted of several phases: assessment of laboratory needs of all 12 countries engaged in the programme; addressing gaps identified during the assessment; and monitoring and evaluation of the progress achieved. After one year of PEPFAR collaboration with national governments and other partners, laboratory services and systems greatly improved. Some of the milestones include: (1) the accreditation of a public laboratory; (2) improved access to HIV diagnosis with faster turnaround time; (3) establishment of capacity for platforms for DNA PCR, viral load and HIV drug resistance; (4) development of the laboratory workforce; and (5) establishment of a framework for implementation of sustainable quality management systems for laboratory accreditation. The progress recorded in strengthening laboratory health systems after one year of initiating this collaboration shows that with a rigorous initial assessment, programme design and intervention and strategic partnership, national laboratory health systems can be greatly enhanced to support programme implementation. Continued collaboration and country leadership is critical to create an integrated and sustainable laboratory network in the Caribbean. PMID:22519703

Individual dose monitoring of the nuclear medicine departments staff controlled by Central Laboratory for Radiological Protection.  

PubMed

Presented paper describes the results of the individual doses measurements for ionizing radiation, carried out by the Laboratory of Individual and Environmental Doses Monitoring (PDIS) of the Central Laboratory for Radiological Protection in Warsaw (CLOR) for the medical staff employees in several nuclear medicine (NM) departments across Poland. In total there are48 NM departments in operation in Poland [1] (consultation in Nuclear Atomic Agency). Presented results were collected over the period from January 2011 to December 2011 at eight NM departments located in Krakow, Warszawa (two departments), Rzeszow (two departments), Opole, Przemysl and Gorzow Wielkopolski. For radiation monitoring three kinds of thermo luminescence dosimeters (TLD) were used. The first TLD h collected information about whole body (C) effective dose, the second dosimeter was mounted in the ring (P) meanwhile the third on the wrist (N) of the tested person. Reading of TLDs was performed in quarterly periods. As a good approximation of effective and equivalent dose assessment of operational quantities both the individual dose equivalent Hp(10) and the Hp(0.07) were used. The analysis of the data was performed using two methods The first method was based on quarterly estimations of Hp(10)q and Hp(0.07)q while the second measured cumulative annual doses Hp(10)a and Hp(0.07)a. The highest recorded value of the radiation dose for quarterly assessments reached 24.4 mSv and was recorded by the wrist type dosimeter worn by a worker involved in source preparation procedure. The mean values of Hp(10)q(C type dosimeter) and Hp(0.07)q (P and N type dosimeter) for all monitored departments were respectively 0.46 mSv and 3.29 mSv. There was a strong correlation between the performed job and the value of the received dose. The highest doses always were absorbed by those staff members who were involved in sources preparation. The highest annual cumulative dose for a particular worker in the considered time period was 4.22 mSv for Hp(10)a and 67.7 mSv for Hp(0.07)a. In 2011 no case of exceeding the allowed dose limits was noted. PMID:24068634

An aerial radiological survey of the Ames Laboratory and surrounding area, Ames, Iowa. Date of survey: July 1991  

SciTech Connect

An aerial radiological survey of the Ames Laboratory and surrounding area in Ames, Iowa, was conducted during the period July 15--25, 1991. The purpose of the survey was to measure and document the terrestrial radiological environment at the Ames Laboratory and the surrounding area for use in effective environmental management and emergency response planning. The aerial survey was flown at an altitude of 200 feet (61 meters) along a series of parallel lines 350 feet (107 meters) apart. The survey encompassed an area of 36 square miles (93 square kilometers) and included the city of Ames, Iowa, and the Iowa State University. The results are reported as exposure rates at 1 meter above ground level (inferred from the aerial data) in the form of a gamma radiation contour map. Typical background exposure rates were found to vary from 7 to 9 microroentgens per hour ({mu}R/h). No anomalous radiation levels were detected at the Ames Laboratory. However, one anomalous radiation source was detected at an industrial storage yard in the city of Ames. In support of the aerial survey, ground-based exposure rate and soil sample measurements were obtained at several sites within the survey perimeter. The results of the aerial and ground-based measurements were found to agree within the expected uncertainty of {+-}15%.

A sustainable training strategy for improving health care following a catastrophic radiological or nuclear incident.  

PubMed

The detonation of a nuclear device in a US city would be catastrophic. Enormous loss of life and injuries would characterize an incident with profound human, political, social, and economic implications. Nevertheless, most responders have not received sufficient training about ionizing radiation, principles of radiation safety, or managing, diagnosing, and treating radiation-related injuries and illnesses. Members throughout the health care delivery system, including medical first responders, hospital first receivers, and health care institution support personnel such as janitors, hospital administrators, and security personnel, lack radiation-related training. This lack of knowledge can lead to failure of these groups to respond appropriately after a nuclear detonation or other major radiation incident and limit the effectiveness of the medical response and recovery effort. Efficacy of the response can be improved by getting each group the information it needs to do its job. This paper proposes a sustainable training strategy for spreading curricula throughout the necessary communities. It classifies the members of the health care delivery system into four tiers and identifies tasks for each tier and the radiation-relevant knowledge needed to perform these tasks. By providing education through additional modules to existing training structures, connecting radioactive contamination control to daily professional practices, and augmenting these systems with just-in-time training, the strategy creates a sustainable mechanism for giving members of the health care community improved ability to respond during a radiological or nuclear crisis, reducing fatalities, mitigating injuries, and improving the resiliency of the community.

Quality-assurance program for field health laboratories  

SciTech Connect

The Federal Mine Safety and Health Act of 1977 (and previously the Federal Coal Mine Health and Safety Act of 1969) established mandatory dust standards for coal mines. Title II requires the Secretary of Labor to make frequent inspections of coal mines to determine compliance with the mandated 2.0 mg/cu m respirable-dust standard. Such inspections are made by representatives of the Secretary, who are coal-mine inspectors of the Mine Safety and Health Administration (MSHA). Sampling equipment used to assess respirable dust concentrations is calibrated and maintained at local field laboratories located in each Coal Mine Safety and Health district. Samples collected during inspections are weighed and analyzed at these laboratories. A selected number of laboratories are also qualified to weigh operator samples in accordance with provisions promulgated in Title 30, Code of Federal Regulations, Part 70. This paper describes the quality-assurance program conducted to assure the performance integrity of the field laboratories in the maintenance and calibration of respirable-dust-sampling equipment and the weighing of respirable coal mine dust samples.

Radiological health risk evaluation of radium contaminated land: a real life implementation.  

PubMed

A plot of land, currently used for dairy farming, has been contaminated over the years with radium due to the operation of one of the world's largest radium production plants. Within the framework of a global remediation approach for the plant surroundings, the land owner needed advice for a future destination of the land. Therefore, the radium contamination was accurately mapped, and on the basis of its severity a practically feasible subdivision of the land into four plots was proposed. For all four plots, the radiological risk was evaluated for the current type of land use and for possible alternative types. Hence a clear and useable advice could be formulated to the authorities reconciling public health, economic and practical issues. PMID:15671056

Georgia Tech video-based MS program in health physics/radiological engineering  

SciTech Connect

For the past several years, the health physics/radiation protection field has experienced a significant shortage of qualified professionals. The shortage is expected to continue for foreseeable future given the continued demand by both nuclear and medical facilities and the expected growth in the areas of waste management and environmental remediation. In response to such a shortage, beginning in the fall of 1984, Georgia Institute of Technology (Georgia Tech) established a video-based instruction program that enables professionals in the nuclear field to earn a master of science degree in health physics/radiological engineering while working at a distant nuclear facility. The admission criteria and curricular requirements for the program are identical to those for the resident (on-campus) students (except that weekly attendance at departmental seminars is excused). The program is designed for students with undergraduate degrees in health physics, engineering, or appropriate sciences such as physics, chemistry, or biology. A total of 50 quarter credit hours is required, so that a student who takes one course per quarter can complete the program in four years.

Clinical and radiological assessment of effects of long-term corticosteroid therapy on oral health  

PubMed Central

Background: Corticosteroids (Cs) are used widely for their anti-inflammatory and immunosuppressive properties. They have the potential to cause dramatic improvement as well as produce equally dramatic adverse effects. The clinical misuse like over prescription of the drug should be avoided. Long-term administration may cause many adverse effects leading to impaired oral health. Oral health is usually not considered during management of patients on long-term corticosteroid therapy. The aim of this study was to assess the oral health status and radiological changes in the jaw bones of the patients under long-term corticosteroid therapy. Materials and Methods: Oral health of 100 patients under long-term corticosteroid therapy with a minimum of 3 months duration was compared with sex- and age-matched 100 healthy controls. The clinical examination included complete examination of the mouth and periodontal status. Radiographic evaluation of bone with the help of intra oral periapical radiograph and digital orthopantomograph and levels of serum calcium, alkaline phosphatase, and random blood sugar were assessed. ‘Chi-square test’, ‘Kolmogorov-Smirnov test’ and ‘Mann-Whitney U test’ were used for statistical analysis. P > 0.05 was considered significant. Results: Patients on steroids exhibited significantly higher levels of candidiasis and clinical attachment loss of the periodontal ligament, probing pocket depth. Bone density was significantly lower in the study group than that in the control group. Random blood glucose was significantly higher and significant lower levels of calcium were observed in patients on steroids. Conclusion: Long-term use of Cs may affect oral health adversely leading to candidiasis as well as impair bone metabolism leading to a considerable decrease in the mandibular bone mineral density.

Replacement of the Idaho National Engineering Laboratory Health Physics Instrumentation Laboratory  

SciTech Connect

The DOE-Idaho Operations Office (DOE-ID) has prepared an environmental assessment (EA) on the replacement of the Idaho National Engineering Laboratory Health Physics Instrumentation Laboratory at the Idaho National Engineering Laboratory (INEL). The purpose of this project is to replace the existing Health Physics Instrumentation Laboratory (HPIL) with a new facility to provide a safe environment for maintaining and calibrating radiation detection instruments used at the Idaho National Engineering Laboratory. The existing HPIL facility provides portable health physics monitoring instrumentation and direct reading dosimetry procurement, maintenance and calibration of radiation detection instruments, and research and development support-services to the INEL and others. However, the existing facility was not originally designed for laboratory activities and does not provide an adequate, safe environment for calibration activities. The EA examined the potential environmental impacts of the proposed action and evaluated reasonable alternatives, including the no action alternative in accordance with the Council on Environmental Quality (CEQ) Regulations (40 CFR Parts 1500-1508). Based on the environmental analysis in the attached EA, the proposed action will not have a significant effect on the human environment within the meaning of the National Environmental Policy Act (NEPA) and 40 CFR Parts 1508.18 and 1508.27. The selected action (the proposed alternative) is composed of the following elements, each described or evaluated in the attached EA on the pages referenced. The proposed action is expected to begin in 1997 and will be completed within three years: design and construction of a new facility at the Central Facility Area of the INEL; operation of the facility, including instrument receipt, inspections and repairs, precision testing and calibration, and storage and issuance. The selected action will result in no significant environmental impacts.

Assessment of entrance surface dose and health risk from common radiology examinations in Iran.  

PubMed

Medical X-ray exposures are the largest man-made source of population exposure to ionising radiation in many countries. Although information on medical exposure is already incorporated into national legislative documents, in Isfahan there is no data on the assessment of patient's entrance surface dose (ESD) and the health risk from conventional radiography in daily clinical practice. The aim of this study was to investigate ESDs and the consequent health risk for the patients undergoing routine X-ray procedures in hospitals  under the control of Isfahan University of Medical Sciences, Iran, in year 2011. The values of ESDs were measured for common radiographical examinations with the highest absorbed dose to the patient in seven hospitals (Alzahra, Ashrafi-Khomeini-shahr, Feyz, Isabne-Maryam, Kashani, Nour-Aliasghar and Seyed-Al Shohada) and six stationary X-ray machines (General Electric, USA; Phillips, The Netherlands; Siemens, Germany; Shimadzu, Japan; Toshiba, Japan and Varian, USA). The results of the ESD measurements as well as the calculated effective dose values between different X-ray examinations showed values significantly greater than those recorded in some other countries especially for the high tube potential technique (such as the skull) by factors of 2.5-5.0. Based on the fatality risk of 5 % per sievert, it was estimated that, for chest and skull examinations approximately two (40.18 person-Sv×5 % per sievert) and one (2.53 person-Sv×5 % per sievert) cases of health risk, respectively, may in the future be attributable to diagnostic X rays done in year 2011 in Isfahan. Efforts should be taken to further lower patient doses while securing image quality. The need to provide relevant education and training to staff in the radiology sections is of utmost importance.

Los Alamos National Laboratory's environmental surveillance and radiological emergency vehicle and the Co-60 incident  

SciTech Connect

A 4-wheel drive van has been outfitted at Los Alamos for environmental surveillance and radiological emergencies. The van's capabilities were described at this conference in 1982. The rapid gamma search and spectral analysis capabilities were utilized in conjunction with the cobalt-60 (/sup 60/Co) teletherapy source incident in Juarez, Mexico. Assistance was requested by the State of New Mexico (through DOE/Albuquerque Area Office) in January 1984 to perform initial in-situ isotopic identification of the contaminated steel that was first discovered in the United States by Los Alamos. The van's capabilities were again called upon in March 1984 to survey the New Mexico highways using the highly sensitive delta count rate monitoring system for /sup 60/Co pellets that may have been tracked into the state. This paper provides (1) setup and results of the surveys conducted with the van, (2) interactions with the press, and (3) an evaluation of the van's usefulness in such an emergency response. 2 references, 5 figures.

Radiological environmental monitoring report for Brookhaven National Laboratory 1967--1970  

SciTech Connect

Brookhaven National Laboratory (BNL) was established in 1947 on the former Army Camp Upton site located in central Long Island, New York. From the very beginning, BNL has monitored the environment on and around the Laboratory site to assess the effects of its operations on the environment. This document summarizes the environmental data collected for the years 1967, 1968, 1969, and 1970. Thus, it fills a gap in the series of BNL annual environmental reports beginning in 1962. The data in this document reflect measurements for those four years of concentrations and/or amounts of airborne radioactivity, radioactivity in streams and ground water, and external radiation levels in the vicinity of BNL. Also included are estimates, made at that time, of BNL`s contribution to radioactivity in the environment. Among the major scientific facilities operated at BNL are the High Flux Beam Reactor, Medical Research Reactor, Brookhaven Graphite Research Reactor, Alternating Gradient Synchrotron, and the 60-inch Cyclotron.

Factors that must be considered include not only the financial implications, but also questions of quality and academic interests such as teaching and training. Laboratories must provide a service that the purchaser wishes to buy and must be successful in overcoming competition from the private sector. Each component part of the overall service must be analyzed in order that the laboratory is efficiently structured to provide an optimum service. A good understanding of management issues and a flexible approach are paramount in the provision of efficient, cost-effective and quality service for the ultimate benefit of the patient.

RADIOLOGICAL EMISSIONS AND ENVIRONMENTAL MONITORING FOR BROOKHAV EN NATIONAL LABORATORY, 1947 - 1961.  

SciTech Connect

Brookhaven National Laboratory (BNL) has monitored its releases to the environment since its inception in 1947. From 1962 to 1966 and from 1971 to the present, annual reports,were published that recorded the emissions and releases to the environment from Laboratory operations. In 1998, a report was written to summarize the environmental data for the years 1967 to 1970. One of the purposes of the current report is to complete BNL's environmental history by covering the period from 1948 through 1961. The activities in 1947 were primarily organizational and there is no information on the use of radiation at the Laboratory before 1948. An additional objective of this report is to provide environmental data to the Agency for Toxic Substances and Disease Registry (ATSDR). The report does not provide an estimate of the doses associated with BNL operations. The report is comprised of two parts. The first part is a summary of emissions, releases, and environmental monitoring information including a discussion of the uncertainties in these data. Part two contains the detailed information on the approach taken to estimate the releases from the fuel cartridge failures at the Brookhaven Graphite Research Reactor (BGRR). A series of appendices present more detailed information on these events in tabular form. The approach in this report is to be reasonable, conservative, (pessimistic), and transparent in estimating releases from fuel cartridge ruptures. Clearly, reactor stack monitoring records and more extensive records would have greatly improved this effort, but in accordance with Atomic Energy Commission (AEC) Appendix 0230 Annex C-9, many of the detailed records from this time were not retained.

Mass violence and early mental health intervention: a proposed application of best practice guidelines to chemical, biological, and radiological attacks.  

PubMed

Based on past episodes, there will be psychological sequelae to chemical, biological, and radiological attacks. Some of the psychological morbidity should be able to be ameliorated through planning and appropriate early intervention. Key components of early intervention are illustrated following a hypothetical scenario of a bomb and anthrax threat near the Pentagon. Many of these components, such as monitoring clear, consistent messages about health risks, are provided by physicians or politicians, not mental health providers, but have a serious impact on the mental health of the population. We hope that this scenario and the principles of response will prove useful to planners of emergency preparedness and responders in the case of an actual attack. PMID:15379065

Amendments to the Center for Devices and Radiological Health federal performance standard for laser products.  

PubMed

Federal law requires that all laser products that are imported into or introduced into commerce in the United States comply with the performance standard published in the Code of Federal Regulations (CRF), Title 21, Parts 1040.10 and 1040.11, administered by the Center for Devices and Radiological Health (CDRH), US Food and Drug Administration. Although it contains somewhat different requirements for hazard classification, engineering controls and labeling, the ANSI Z136.1 standard defers to the CDRH standard. The CDRH standard became effective in August, 1976 and was amended, in 1978 and also in 1985. In the early 1990s, US experts met to formulate an approach to bring the requirements of the CDRH standard and those of the International Electrotechnical Commission (IEC) standard, IEC 825, into closer agreement in order to lower barriers to international trade and to remove any excessive compliance burdens on manufacturers. In 1993, the CDRH published, formally in the Federal Register and informally, a Notice of Intent to amend the CDRH standard. Responses to those notices have now been analyzed and informal draft amendments were distributed in 1996. This draft is now being prepared for formal issuance as a Notice of Proposed Rulemaking. Meanwhile, the IEC standard was amended in 1993 and republished as IEC 825-1; these amendments created considerable controversy since they resulted in over classification of the hazard of many products, especially light emitting diodes (LEDs) that have a large divergence and increased source dimensions. Additional amendments are now being developed to correct this problem. The CDRH has carefully monitored developments in the IEC and actively participated in its proceedings as a guide in developing its own proposal. This paper describes the major changes that are being proposed for the CDRH standard and presents some rationale for the major changes. The more significant changes include expansion of applicability to include LEDs, reduced emission durations for classification, revised measurement for hazard classification, reduced performance requirements for lower power visible radiation products, and revised requirements for medical products.

RISKIND: A computer program for calculating radiological consequences and health risks from transportation of spent nuclear fuel  

SciTech Connect

This report presents the technical details of RISIUND, a computer code designed to estimate potential radiological consequences and health risks to individuals and the collective population from exposures associated with the transportation of spent nuclear fuel. RISKIND is a user-friendly, semiinteractive program that can be run on an IBM or equivalent personal computer. The program language is FORTRAN-77. Several models are included in RISKIND that have been tailored to calculate the exposure to individuals under various incident-free and accident conditions. The incidentfree models assess exposures from both gamma and neutron radiation and can account for different cask designs. The accident models include accidental release, atmospheric transport, and the environmental pathways of radionuclides from spent fuels; these models also assess health risks to individuals and the collective population. The models are supported by databases that are specific to spent nuclear fuels and include a radionudide inventory and dose conversion factors.

RISKIND: A computer program for calculating radiological consequences and health risks from transportation of spent nuclear fuel  

SciTech Connect

This report presents the technical details of RISKIND, a computer code designed to estimate potential radiological consequences and health risks to individuals and the collective population from exposures associated with the transportation of spent nuclear fuel. RISKIND is a user-friendly, interactive program that can be run on an IBM or equivalent personal computer under the Windows{trademark} environment. Several models are included in RISKIND that have been tailored to calculate the exposure to individuals under various incident-free and accident conditions. The incident-free models assess exposures from both gamma and neutron radiation and can account for different cask designs. The accident models include accidental release, atmospheric transport, and the environmental pathways of radionuclides from spent fuels; these models also assess health risks to individuals and the collective population. The models are supported by databases that are specific to spent nuclear fuels and include a radionuclide inventory and dose conversion factors. In addition, the flexibility of the models allows them to be used for assessing any accidental release involving radioactive materials. The RISKIND code allows for user-specified accident scenarios as well as receptor locations under various exposure conditions, thereby facilitating the estimation of radiological consequences and health risks for individuals. Median (50% probability) and typical worst-case (less than 5% probability of being exceeded) doses and health consequences from potential accidental releases can be calculated by constructing a cumulative dose/probability distribution curve for a complete matrix of site joint-wind-frequency data. These consequence results, together with the estimated probability of the entire spectrum of potential accidents, form a comprehensive, probabilistic risk assessment of a spent nuclear fuel transportation accident.

The evolution of the international system of radiological protection: food for thought from the Nuclear Energy Agency Committee on Radiation Protection and Public Health.  

PubMed

From its inception, the Nuclear Energy Agency (NEA), which is part of the broader Organisation for Economic Co-operation and Development, has contributed to the development of international radiological protection norms and standards. This continues today, in the form of studies and workshops to assist radiological protection policy makers, regulators and practitioners to develop concepts and approaches to help the international system of radiological protection, as recommended by the International Commission on Radiological Protection (ICRP), to evolve to better serve societal needs. The NEA's Committee on Radiation Protection and Public Health (CRPPH), in providing this support, has collaborated closely with the ICRP and strongly supports the current ICRP recommendation development process. In particular, active dialogue with a broad range of stakeholders is contributing to the evolution of concepts towards consensus on new ICRP recommendations. The CRPPH, as a body of ICRP recommendation practitioners, feels that the public, workers and the environment are well protected by the current radiological protection system, but agrees that a new consolidation and clarification of ICRP recommendations would be of value. The intent of the CRPPH in collaborating with ICRP is to develop a system of radiological protection that is simplified, more coherent, firmly based upon science and more clearly presented than the current system. This paper summarises the more detailed views of the CRPPH on the evolution of the system of radiological protection. PMID:14582716

Environmental, safety, and health plan for the remedial investigation of Waste Area Grouping 10, Operable Unit 3, at Oak Ridge National Laboratory, Oak Ridge, Tennessee. Environmental Restoration Program  

SciTech Connect

This document outlines the environmental, safety, and health (ES&H) approach to be followed for the remedial investigation of Waste Area Grouping (WAG) 10 at Oak at Ridge National Laboratory. This ES&H Plan addresses hazards associated with upcoming Operable Unit 3 field work activities and provides the program elements required to maintain minimal personnel exposures and to reduce the potential for environmental impacts during field operations. The hazards evaluation for WAG 10 is presented in Sect. 3. This section includes the potential radiological, chemical, and physical hazards that may be encountered. Previous sampling results suggest that the primary contaminants of concern will be radiological (cobalt-60, europium-154, americium-241, strontium-90, plutonium-238, plutonium-239, cesium-134, cesium-137, and curium-244). External and internal exposures to radioactive materials will be minimized through engineering controls (e.g., ventilation, containment, isolation) and administrative controls (e.g., procedures, training, postings, protective clothing).

Carcinoma of unknown primary: key radiological issues from the recent National Institute for Health and Clinical Excellence guidelines  

PubMed Central

Carcinoma of unknown primary origin (CUP) accounts for 3–5% of cancer cases and is the fourth most common cause of cancer death in the UK. CUP management is challenging, partly owing to the heterogeneity of the condition and its presentation, but also owing to the lack of dedicated clinical services for these patients. The recent National Institute for Health and Clinical Excellence (NICE) guidelines on metastatic malignancy of unknown primary origin were developed to improve the co-ordination of diagnostic and clinical services at hospitals treating cancer patients in England and Wales, in particular by the setting up of CUP teams to manage these patients. Radiologists have a vital role in the diagnosis of these patients and should work closely with the CUP team to streamline the diagnostic pathway. This article summarises areas of the NICE guidelines relevant to radiology and discusses the radiological management of patients with CUP, including initial investigation, the importance of biopsy, the management of specific presentations, special investigations and organisational issues.

Voluntary electronic reporting of laboratory errors: an analysis of 37,532 laboratory event reports from 30 health care organizations.  

PubMed

Laboratory testing is essential for diagnosis, evaluation, and management. The objective was to describe the type of laboratory events reported in hospitals using a voluntary electronic error reporting system (e-ERS) via a cross-sectional analysis of reported laboratory events from 30 health organizations throughout the United States (January 1, 2000, to December 31, 2005). A total of 37,532 laboratory-related events were reported, accounting for 14.1% of all reported quality events. Preanalytic laboratory events were the most common (81.1%); the top 3 were specimen not labeled (18.7%), specimen mislabeled (16.3%), and improper collection (13.2%). A small number (0.08%) of laboratory events caused permanent harm or death; 8% caused temporary harm. Most laboratory events (55%) did not cause harm. Laboratory errors constitute 1 of 7 quality events. Laboratory errors often are caused by events that precede specimen arrival in the lab and should be preventable with a better labeling processes and education. Most laboratory errors do not lead to patient harm. PMID:21918013

Derivation of residual radioactive material guidelines for the Laboratory for Energy-Related Health Research site  

SciTech Connect

Residual radioactive material guidelines were derived for the Laboratory for Energy-Related Health Research (LEHR) Environmental Restoration (ER) site in Davis, California. The guideline derivation was based on a dose limit of 100 mrem/yr. The US Department of Energy (DOE) residual radioactive material guideline computer code was used in this evaluation. This code implements the methodology described in the DOE manual for implementing residual radioactive material guidelines. Three potential site utilization scenarios were considered with the assumption that following ER action, the site will be used without radiological restrictions. The defined scenarios vary with regard to use of the site, time spent at the site, and sources of food consumed. The results of the evaluation indicate that the basic dose limit of 100 mrem/yr will not be exceeded, provided that the soil concentrations of these radionuclides at the LEHR site do not exceed the scenario-specific values calculated by this study. Except for the extent of the contaminated zone (which is very conservative), assumptions used are as site-specific as possible, given available information. The derived guidelines are single- radionuclide guidelines and are linearly proportional to the dose limit used in the calculations. In setting the actual residual soil contamination guides for the LEHR site, DOE will apply the as low as reasonably achievable policy to the decision-making process, along with other factors such as whether a particular scenario is reasonable and appropriate, as well as using site-specific inputs to computer models based on data not yet fully determined.

Economic Analysis of Requests for Laboratory Tests in Primary Health Care Centers  

PubMed Central

Introduction: Operation of the Primary health care center and Medical-biochemical laboratories depends on the number of performed laboratory tests. The number of unnecessary tests significantly affect the operation of health institutions. Material and methods: We analyzed the 1000 requests for laboratory tests at the Primary Health Care Centre in Gracanica from primary care units. Based on the requests for laboratory diagnostics advisable diagnoses from primary health care unit in the Primary Health Care Center (PHC) we made an economic analysis of the total required laboratory tests in the requests for laboratory diagnosis. Incorporating the economic analysis of laboratory tests in requests for laboratory diagnosis by doctors in primary health care (PHC) and the economic analysis of laboratory tests by the disease in primary health care. Results: The economic value of 5333 laboratory tests was 84 312 points (1 point is 0.80 KM). Of the total value of the index score requirements of GPs are 44, 1%, the requirement of family doctors account for 40% and requirements of other specialists make up 15, 9%.. Discussion: In the requests of the PHC units for laboratory tests are required all levels of services: urine, CBC, SE, glucose, bilirubine, ALT, AST, AF, CK, cholesterol, HDL chol., triglicerdes, creatinine, urea, uric acid, CRP, fibrinogen, calcium and phosphorus. The following requests are the most common laboratory tests: urine, CBC, blood glucose, cholesterol, triglycerides, aminotransferases, creatinine, urea. The doctors in family practice most often requested: blood glucose, urine, CBC, SE, TGL. , Chol., ALT, AST, creatinine and urea. General practitioners were demanding more cholesterol and triglycerides, and family medicine doctors were demanding less cholesterol and triglycerides and more often CRP, fibrinogen, ALT, AST, what from the level of economic cost analysis rises the issue whether this was justified?

Needs analysis and project schedule for the Los Alamos National Laboratory (LANL) Health Physics Analysis Laboratory (HPAL) upgrade  

SciTech Connect

This report is a needs assessment and project schedule for the Health Physics Analysis Laboratory (HPAL) upgrade project at Los Alamos National Laboratory (LANL). After reviewing current and projected HPAL operations, two custom-developed laboratory information management systems (LIMS) for similar facilities were reviewed; four commercially available LIMS products were also evaluated. This project is motivated by new regulations for radiation protection and training and by increased emphasis on quality assurance (QA). HPAL data are used to: protect the health of radiation workers; document contamination levels for transportation of radioactive materials and for release of materials to the public for uncontrolled use; and verify compliance with environmental emission regulations. Phase 1 of the HPAL upgrade project concentrates on four types of counting instruments which support in excess of 90% of the sample workload at the existing central laboratories. Phase 2 is a refinement phase and also integrates summary-level databases on the central Health, Safety, and Environment (HSE) VAX. Phase 3 incorporates additional instrument types and integrates satellite laboratories into the HPAL LIMS. Phase 1 will be a multi-year, multimillion dollar project. The temptation to approach the upgrade of the HPAL program in a piece meal fashion should be avoided. This is a major project, with clearly-defined goals and priorities, and should be approached as such. Major programmatic and operational impacts will be felt throughout HSE as a result of this upgrade, so effective coordination with key customer contacts will be critical.

Post-remedial-action radiological survey of the Westinghouse Advanced Reactors Division Plutonium Fuel Laboratories, Cheswick, Pennsylvania, October 1-8, 1981  

SciTech Connect

The post-remedial-action radiological assessment conducted by the ANL Radiological Survey Group in October 1981, following decommissioning and decontamination efforts by Westinghouse personnel, indicated that except for the Advanced Fuels Laboratory exhaust ductwork and north wall, the interior surfaces of the Plutonium Laboratory and associated areas within Building 7 and the Advanced Fuels Laboratory within Building 8 were below both the ANSI Draft Standard N13.12 and NRC Guideline criteria for acceptable surface contamination levels. Hence, with the exceptions noted above, the interior surfaces of those areas within Buildings 7 and 8 that were included in the assessment are suitable for unrestricted use. Air samples collected at the involved areas within Buildings 7 and 8 indicated that the radon, thoron, and progeny concentrations within the air were well below the limits prescribed by the US Surgeon General, the Environmental Protection Agency, and the Department of Energy. The Building 7 drain lines are contaminated with uranium, plutonium, and americium. Radiochemical analysis of water and dirt/sludge samples collected from accessible Low-Bay, High-Bay, Shower Room, and Sodium laboratory drains revealed uranium, plutonium, and americium contaminants. The Building 7 drain lines hence are unsuitable for release for unrestricted use in their present condition. Low levels of enriched uranium, plutonium, and americium were detected in an environmental soil coring near Building 8, indicating release or spillage due to Advanced Reactors Division activities or Nuclear Fuel Division activities undr NRC licensure. /sup 60/Co contamination was detected within the Building 7 Shower Room and in soil corings from the environs of Building 7. All other radionuclide concentrations measured in soil corings and the storm sewer outfall sample collected from the environs about Buildings 7 and 8 were within the range of normally expected background concentrations.

Dose-Rate Dependence of High-Dose Health Effects in Humans from Photon Radiation with Application to Radiological Terrorism  

SciTech Connect

In 1981, as part of a symposium entitled ''The Control of Exposure of the Public to Ionizing Radiation in the Event of Accident or Attack,'' Lushbaugh, H?bner, and Fry published a paper examining ''radiation tolerance'' of various human health endpoints as a function of dose rate. This paper may not have received the notice it warrants. The health endpoints examined by Lushbaugh et al. were the lethal dose that will kill 50% of people within 60 days of exposure without medical care (LD50/60); severe bone marrow damage in healthy men; severe bone marrow damage in leukemia patients; temporary sterility (azoospermia); reduced male fertility; and late effects such as cancer. Their analysis was grounded in extensive clinical experience and anchored to a few selected data points, and based on the 1968 dose-rate dependence theory of J.L. Bateman. The Lushbaugh et al. paper did not give predictive equations for the relationships, although they were implied in the text, and the relationships were presented in a non-intuitive way. This work derives the parameters needed in Bateman's equation for each health endpoint, tabulates the results, and plots them in a more conventional manner on logarithmic scales. The results give a quantitative indication of how the human organism can tolerate more radiation dose when it is delivered at lower dose rates. For example, the LD50/60 increases from about 3 grays (300 rads) when given at very high dose rates to over 10 grays (1,000 rads) when given at much lower dose rates over periods of several months. The latter figure is borne out by the case of an individual who survived for at least 19 years after receiving doses in the range of 9 to 17 grays (900-1700 rads) over 106 days. The Lushbaugh et al. work shows the importance of sheltering when confronted with long-term exposure to radiological contamination such as would be expected from a radiological dispersion event, reactor accident, or ground-level nuclear explosion.

Health Canada Safety Code 35: awareness of the impacts for diagnostic radiology in Canada.  

PubMed

Health Canada Safety Code 35 brings Canada's diagnostic imaging radiation output and protection standards to an international level. This Safety Code is comprehensive and will have broad implications for most health care facilities. This Safety Code outlines quality control procedures that will ultimately reduce patient dose while providing the best quality diagnostic images, all within a safe working environment. However, the Safety Code has some important omissions and errors of which radiologists should be aware, especially if they act as radiation safety officers. We hope that highlighting these issues will be the beginning of an ongoing dialogue between Health Canada, radiologists, medical physicists, and technologists that will not only bring awareness of Safety Code 35 but will provide a basis for updating, correcting, and improving future revisions of the Safety Code.

The World Health Organization African region laboratory accreditation process: improving the quality of laboratory systems in the African region.  

PubMed

Few developing countries have established laboratory quality standards that are affordable and easy to implement and monitor. To address this challenge, the World Health Organization Regional Office for Africa (WHO AFRO) established a stepwise approach, using a 0- to 5-star scale, to the recognition of evolving fulfillment of the ISO 15189 standard rather than pass-fail grading. Laboratories that fail to achieve an assessment score of at least 55% will not be awarded a star ranking. Laboratories that achieve 95% or more will receive a 5-star rating. This stepwise approach acknowledges to laboratories where they stand, supports them with a series of evaluations to use to demonstrate improvement, and recognizes and rewards their progress. WHO AFRO's accreditation process is not intended to replace established ISO 15189 accreditation schemes, but rather to provide an interim pathway to the realization of international laboratory standards. Laboratories that demonstrate outstanding performance in the WHO-AFRO process will be strongly encouraged to enroll in an established ISO 15189 accreditation scheme. We believe that the WHO-AFRO approach for laboratory accreditation is affordable, sustainable, effective, and scalable. PMID:20716795

Initial laboratory studies into the chemical and radiological aging of organic materials in underground storage tanks at the Hanford Complex  

SciTech Connect

The underground storage tanks at the Hanford Complex contain wastes generated over many years from plutonium production and recovery processes, and mixed wastes from radiological degradation processes. The chemical changes of the organic materials used in the extraction processes have a direct bearing on several specific safety issues, including potential energy releases from these tanks. The major portion of organic materials that have been added to the tanks consists of tributyl phosphate, dibutyl phosphate, butyl alcohol, hexone (methyl isobutyl ketone), normal paraffin hydrocarbons (NPH), ethylenediaminetetraacetic acid (EDTA), hydroxyethylethylenediaminetriadetic acid (HEDTA), other complexants, and lesser quantities of ion exchange polymers and minor organic compounds. A study of how thermal and radiological processes that may have changed the composition of organic tanks constituents has been initiated after a review of the open literature revealed little information was available about the rates and products of these processes under basic pH conditions. This paper will detail the initial findings as they relate to gas generation, e.g. H{sub 2}, CO, NH{sub 3}, CH{sub 4}, and to changes in the composition of the organic and inorganic components brought about by ``Aging`` processes.

Effect of the Duration Time of a Nuclear Accident on Radiological Health Consequences  

PubMed Central

This study aimed to quantify the effect of duration time of a nuclear accident on the radiation dose of a densely populated area and the resulting acute health effects. In the case of nuclear accidents, the total emissions of radioactive materials can be classified into several categories. Therefore, the release information is very important for the assessment of risk to the public. We confirmed that when the duration time of the emissions are prolonged to 7 hours, the concentrations of radioactive substances in the ambient air are reduced by 50% compared to that when the duration time of emission is one hour. This means that the risk evaluation using only the first wind direction of an accident is very conservative, so it has to be used as a screening level for the risk assessment. Furthermore, it is judged that the proper control of the emission time of a nuclear accident can minimize the health effects on residents.

Surface radiological investigations of Trench 6 and low-level waste Line Leak Site 7. 4b at the Oak Ridge National Laboratory, Oak Ridge, Tennessee  

SciTech Connect

A surface radiological investigation of Trench 6 and low-level radioactive waste (LLW) Line Leak Site 7.4b was conducted in July and August 1989 and January 1990 by the Measurement Applications and Development Group, Oak Ridge National Laboratory. The purposes of this survey were (1) to determine the presence, nature, and extent of surface radiological contamination and (2) to recommend interim corrective action to limit human exposures to radioactivity and minimize the potential for contaminant dispersion. Highest surface gamma levels encountered during the survey (39 mR/h) were found just south of the asphalt covering LLW Line Leak Site 7.4b. Elevated surface gamma levels (measuring 28 to 560 {mu}R/h) extended from this area to a width of 100 ft, westward 250 ft, and beyond the survey boundary. Beta-gamma levels up to 17 mrad/h measured on contact with the trunks of trees growing in the area southwest of Trench 6 suggest that three roots are reaching contamination deep within the ground. Since no gamma activity is associated with the trees or their leaves, the elevated beta levels are probably due to the uptake of residual {sup 90}Sr originating from the documented seepage at the Trench 6/Leak Site 7.4b area. Beta activity present in the leaf litter and surface soil indicate that decaying leaves are depositing measurable contaminants on the ground surface. Recommendations for corrective actions are included. 7 refs., 20 figs., 3 tabs.

Results of the radiological and chemical characterization of surface impoundments 3539 and 3540 at Oak Ridge National Laboratory, Oak Ridge, Tennessee  

SciTech Connect

A radiological and chemical characterization survey of impoundments 3539 and 3540 at the Oak Ridge National Laboratory (ORNL) was conducted during December 1997. Impoundments 3539 and 3540 are located in the Surface Impoundments Operable Unit (SIOU) of Waste Area Group 1. The investigation was performed by the Measurement Applications and Development Group of the Life Sciences Division of ORNL at the request of the Department of Energy (DOE) Office of Environmental Restoration. Sampling was conducted in order to quantify the presence of polychlorinated biphenyls (PCBs), Resource Conservation and Recovery Act (RCRA) constituents, and other contaminants of interest in support of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) remediation for the SIOU> The survey included collection of sediment/clay samples, quality control blank water samples and equipment rinsate samples for chemical and radiological analysis. Results show the samples contain traces of various organic, inorganic, and radioactive materials. Of particular interest are PCB values which demonstrate the impoundments are not regulated under the Toxic Substances Control Act.

Capacity building of public health laboratories in Afghanistan: challenges and successes (2007-2011).  

PubMed

The continuing state of conflict and the resulting devastation of infrastructure have made Afghanistan exceptionally vulnerable to disease epidemics. The paper reports initiatives by the United States Naval Medical Research Unit No. 3 to promote capacity building in a number of key medical laboratories and enable the Afghans to detect emerging and re-emerging diseases of public health importance. Equipment, supplies and laboratory staff training were critical for disease diagnosis and fulfilment of obligations of the International Health Regulations 2005. Accordingly, many diseases outbreaks were recently identified, including avian and pandemic influenza, febrile illness, watery diarrhoea, jaundice and leishmaniasis. Clinical samples and disease vectors were collected for analysis, and microbial isolates were obtained for further characterization. The expanded range and enhanced accuracy of laboratory procedures have facilitated selected local laboratories to monitor, detect, identify, assess, contain and respond to public health threats. Nevertheless, policies of sustainability and infectious diseases control need continuous support and emphasis. PMID:24945560

Health Canada's approach to manage risks to populations at risk during a radiological emergency.  

PubMed

The approach that Health Canada uses to manage risks to individuals and to populations who might be exposed to ionising radiation is based upon the risk management paradigm. The paradigm differs little between an emergency and a non-emergency situations. In both events, technical experts assess the risk by determining the exposure to the source of radiation. They usually calculate the radiation dose and then assess the potential for any health effects. The initial technical assessments often use scoping calculations. The calculations for children recognise that they are smaller and have different metabolic rates and different behaviour from adults. However, most rigorous quantitative models for dosimetry do not differentiate between children and adults. The risk assessments that were conducted to evaluate the contamination of Canadians who were in London during the Litvenenko poisoning are a good example to illustrate this general approach. The scoping risk assessment concluded that the risks to children and adults were low. No Canadian children were exposed to polonium during this event and, to date, there have been no radiation emergencies in Canada where children have been exposed to a significant source of radiation. Therefore, the comparisons between theory and practice are very limited and conclusions are drawn from international experience and other incidents or sources of radiation exposure such as radon and medical exposures.

Laboratory systems and services are critical in global health: time to end the neglect?  

PubMed

The $63 billion comprehensive global health initiative (GHI) emphasizes health systems strengthening (HSS) to tackle challenges, including child and maternal health, HIV/AIDS, family planning, and neglected tropical diseases. GHI and other initiatives are critical to fighting emerging and reemerging diseases in resource-poor countries. HSS is also an increasing focus of the $49 billion program of the US President's Emergency Plan for AIDS Relief and the Global Fund to Fight AIDS, Tuberculosis and Malaria. Laboratory systems and services are often neglected in resource-poor settings, but the funding offers an opportunity to end the neglect. To sustainably strengthen national laboratory systems in resource-poor countries, the following approaches are needed: (1) developing integrative national laboratory strategic plans and policies and building systems to address multiple diseases; (2) establishing public-private partnerships; (3) ensuring effective leadership, commitment, and coordination by host governments of efforts of donors and partners; (4) establishing and/or strengthening centers of excellence and field epidemiology and laboratory training programs to meet short- and medium-term training and retention goals; and (5) establishing affordable, scalable, and effective laboratory accreditation schemes to ensure quality of laboratory tests and bridge the gap between clinicians and laboratory experts on the use of test results.

"Meaningful use" of electronic health records and its relevance to laboratories and pathologists  

PubMed Central

Electronic health records (EHRs) have emerged as a major topic in health care and are central to the federal government’s strategy for transforming healthcare delivery in the United States. Recent federal actions that aim to promote the use of EHRs promise to have significant implications for laboratories and for pathology practices. Under the HITECH (Health Information Technology Economic and Clinical Health) Act, an EHR incentive program has been established through which individual physicians and hospitals can qualify to receive incentive payments if they achieve “meaningful use” of “certified” EHR technology. The rule also establishes payment penalties in future years for eligible providers who have not met the requirements for meaningful use of EHRs. Meaningful use must be achieved using EHR technology that has been certified in accordance with functional and technical criteria that are set forth a regulation that parallels the meaningful use criteria in the incentive program. These actions and regulations are important to laboratories and pathologists for a number of reasons. Several of the criteria and requirements in the meaningful use rules and EHR certification criteria relate directly or indirectly to laboratory testing and laboratory information management, and future stage requirements are expected to impact the laboratory as well. Furthermore, as EHR uptake expands, there will be greater expectations for electronic interchange of laboratory information and laboratory information system (LIS)-EHR interfaces. Laboratories will need to be aware of the technical, operational, and business challenges that they may face as expectations for LIS-EHR increase. This paper reviews the important recent federal efforts aimed at accelerating EHR use, including the incentive program for EHR meaningful use, provider eligibility, and EHR certification criteria, from a perspective of their relevance for laboratories and pathology practices.

The evaluation of the clinical, laboratory and the radiological findings of the fifty-five cases diagnosed with tuberculous, Brucellar and pyogenic spondylodiscitis  

PubMed Central

Objective: In this study, the evaluation of the clinical, laboratory and radiological findings belonging to 55 cases that were hospitalized in our clinic to be followed-up and were diagnosed with tuberculous, brucellar and pyogenic spondylodiscitis (SD) was aimed. Materials and Methods: The cases with SD were evaluated retrospectively. Hematological, serological, biochemical laboratory tests and imaging technics were used for diagnosis. Results: Of 55 cases aged ranging between 25 to 79, 33 (59%) were female. The cases with tuberculous SD (TBSD), brucellar SD (BSD) and pyogenic SD (PSD) were found in 24 (43%), 12 (21%) and in 19 (34%) patients. Erytrocyte sedimentation rate, increased C-reactive protein, and leucocytosis were present in 51 (91%), 22 (39%) and 8 (14%) cases. The number of the cases with history of previous surgery or trauma was 14 (25%). Diagnosis of TBSD was established by acid fast bacilli positiveness and Löwenstein Jensen culture positiveness, in two and seven patients, respectively. While all 12 cases with BSD had positive standard tube aglutination test, only 3 (25%) had hemoculture positivity. In PSDs, diagnosis was confirmed with culture positivity in 9 of 19 cases.Of the cases in our study, 89% responded to medical treatment while three required surgery and three died (5.5% and 5.5%, respectively). Conclusion: SD may develop secondary to infections or following spinal surgical procedures and traumas. Also, the importance of endemicity should be kept in mind, beside the helpful diagnostic findings while treatment regulation.

Analyzing how radiologists recommend follow-up: toward development of an automated tracking and feedback system for clinical, laboratory, and radiologic studies  

NASA Astrophysics Data System (ADS)

Radiologists often recommend further imaging, laboratory or clinical follow-up as part of a study interpretation, but rarely receive feedback as to the results of these additional tests. In most cases, the radiologist has to actively pursue this information by searching through the multiple electronic medical records at our institution. In this work, we seek to determine if it would be possible to automate the feedback process by analyzing how radiologists phrase recommendations for clinical, laboratory or radiologic follow-up. We surveyed a dozen attending radiologists to create a set of phrases conventionally used to indicate the need for follow-up. Next, we mined dictated reports over a 1-year period to quantify the appearance of each of these phrases. We are able to isolate 5 phrases that appear in over 21,000 studies performed during the 1-year period, and classify them by modality. We also validated the query by evaluating one day's worth of reports for follow-up recommendations and assessing the comparative performance of the follow-up query. By automatically mining imaging reports for these key phrases and tracking these patients' electronic medical records for additional imaging or pathology, we can begin to provide radiologists with automated feedback regarding studies they have interpreted. Furthermore, we can analyze how often these recommendations lead to a definitive diagnosis and enable radiologists to adjust their practice and decision-making accordingly and ultimately improve patient care.

Estimating Increased Electronic Laboratory Reporting Volumes for Meaningful Use: ?Implications for the Public Health Workforce  

PubMed Central

Objective: To provide formulas for estimating notifiable disease reporting volume from ‘meaningful use’ electronic laboratory reporting (ELR). Methods: We analyzed two years of comprehensive ELR reporting data from 15 metropolitan hospitals and laboratories. Report volumes were divided by population counts to derive generalizable estimators. Results: Observed volume of notifiable disease reports in a metropolitan area were more than twice national averages. ELR volumes varied by institution type, bed count, and by the level of effort required of health department staff. Conclusions: Health departments may experience a significant increase in notifiable disease reporting following efforts to fulfill meaningful use requirements, resulting in increases in workload that may further strain public health resources. Volume estimators provide a method for predicting ELR transaction volumes, which may support administrative planning in health departments.

A novel influenza A (H1N1) virus detected in April 2009 rapidly spread around the world. North American provincial and state laboratories have well-defined roles and responsibilities, including providing accurate, timely test results for patients and information for regional public health and other decision makers. We used the multidisciplinary response and rapid implementation of process changes based on Lean methods at the provincial public health laboratory in British Columbia, Canada, to improve laboratory surge capacity in the 2009 influenza pandemic. Observed and computer simulating evaluation results from rapid processes changes showed that use of Lean tools successfully expanded surge capacity, which enabled response to the 10-fold increase in testing demands.

Development of a single ion hit facility at the Pierre Sue Laboratory: a collimated microbeam to study radiological effects on targeted living cells.  

PubMed

A single ion hit facility is being developed at the Pierre Süe Laboratory (LPS) since 2004. This set-up will be dedicated to the study of ionising radiation effects on living cells, which will complete current research conducted on uranium chemical toxicity on renal and osteoblastic cells. The study of the response to an exposure to alpha particles will allow us to distinguish radiological and chemical toxicities of uranium, with a special emphasis on the bystander effect at low doses. Designed and installed on the LPS Nuclear microprobe, up to now dedicated to ion beam microanalysis, this set-up will enable us to deliver an exact number of light ions accelerated by a 3.75 MV electrostatic accelerator. An 'in air' vertical beam permits the irradiation of cells in conditions compatible with cell culture techniques. Furthermore, cellular monolayer will be kept in controlled conditions of temperature and atmosphere in order to diminish stress. The beam is collimated with a fused silica capillary tubing to target pre-selected cells. Motorisation of the collimator with piezo-electric actuators should enable fast irradiation without moving the sample, thus avoiding mechanical stress. An automated epifluorescence microscope, mounted on an antivibration table, allows pre- and post-irradiation cell observation. An ultra thin silicon surface barrier detector has been developed and tested to be able to shoot a cell with a single alpha particle. PMID:17218368

Assessment of laboratory logistics management information system practice for HIV/AIDS and tuberculosis laboratory commodities in selected public health facilities in Addis Ababa, Ethiopia  

PubMed Central

Introduction Logistics management information system for health commodities remained poorly implemented in most of developing countries. To assess the status of laboratory logistics management information system for HIV/AIDS and tuberculosis laboratory commodities in public health facilities in Addis Ababa. Methods A cross-sectional descriptive study was conducted from September 2010-January 2011 at selected public health facilities. A stratified random sampling method was used to include a total of 43 facilities which, were investigated through quantitative methods using structured questionnaires interviews. Focus group discussion with the designated supply chain managers and key informant interviews were conducted for the qualitative method. Results There exists a well-designed logistics system for laboratory commodities with trained pharmacy personnel, distributed standard LMIS formats and established inventory control procedures. However, majority of laboratory professionals were not trained in LMIS. Majority of the facilities (60.5%) were stocked out for at least one ART monitoring and TB laboratory reagents and the highest stock out rate was for chemistry reagents. Expired ART monitoring laboratory commodities were found in 25 (73.5%) of facilities. Fifty percent (50%) of the assessed hospitals and 54% of health centers were currently using stock/bin cards for all HIV/AIDS and TB laboratory commodities in main pharmacy store, among these only 25% and 20.8% of them were updated with accurate information matching with the physical count done at the time of visit for hospitals and health centers respectively. Conclusion Even though there exists a well designed laboratory LMIS, keeping quality stock/bin cards and LMIS reports were very low. Key ART monitoring laboratory commodities were stock out at many facilities at the day of visit and during the past six months. Based on findings, training of laboratory personnel's managing laboratory commodities and keeping accurate inventory control procedures were recommended.

DOE operation of LEHR as a functioning research location ceased in 1989, after the completion of three decades of research on the health effects of low-level radiation exposure (primarily strontium-90 and radium-226), using beagles to simulate effects on human health. During 1996, the U.S. Department of Energy (DOE) conducted activities at the Site in support of Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) Environmental remediation and the decontamination and decommissioning (D&D) of Site buildings. Extensive environmental data were collected in 1996 to evaluate appropriate remedial actions for the Site.

[The role of reference laboratories in animal health programmes in South America].  

PubMed

The contribution of the Panamerican Foot and Mouth Disease (FMD) Centre (PANAFTOSA), as an OIE (World organisation for animal health) regional reference laboratory for the diagnosis of FMD and vesicular stomatitis, and for the control of the FMD vaccine, has been of fundamental importance to the development, implementation and harmonisation of modern laboratory procedures in South America. The significance of the work conducted by PANAFTOSA is particularly obvious when one considers the two pillars on which eradication programmes are based, namely: a well-structured regional laboratory network, and the creation of a system which allows technology and new developments to be transferred to Member Countries as quickly and efficiently as possible. Over the past decade, PANAFTOSA has kept pace with the changing epidemiological situation on the continent, and with developments in the international political and economical situation. This has involved the strengthening of quality policies, and the elaboration and implementation of diagnostic tools that make for more thorough epidemiological analyses. The integration of PANAFTOSA into the network of national laboratories and its cooperation with technical and scientific institutes, universities and the private sector means that local needs can be met, thanks to the design and rapid implementation of methodological tools which are validated using internationally accepted criteria. This collaboration, which ensures harmonisation of laboratory tests and enhances the quality of national Veterinary Services, serves to promote greater equity, a prerequisite for regional eradication strategies and this in turn, helps to increase competitiveness in the region.

Laboratories and the health care marketplace: the limits of state workforce policy.  

PubMed

Nearly every state has enacted its own effort to change both the composition and the practice patterns of America's medical workforce. At the same time, the health care marketplace is altering the nation's medical workforce, encouraging more medical students to enter primary care and fewer to become specialists. In this article, I consider various issues raised by these trends. Do the various state programs constitute an effective policy laboratory? Is the market solving problems government could not? Are the government initiatives now irrelevant? I conclude that the market is solving the problem of specialty maldistribution (too many specialists) but not the problem of geographic maldistribution (too many medically underserved communities). I also conclude that state workforce efforts have not constituted good policy laboratories and that only federal action can seriously address the geographic maldistribution problem. PMID:9185018

Educating Medical Laboratory Technologists: Revisiting Our Assumptions in the Current Economic and Health-Care Environment  

PubMed Central

Health care occupies a distinct niche in an economy struggling to recover from recession. Professions related to the care of patients are thought to be relatively resistant to downturns, and thus become attractive to students typically drawn to more lucrative pursuits. Currently, a higher profile for clinical laboratory technology among college students and those considering career change results in larger and better prepared applicant pools. However, after decades of contraction marked by closing of programs, prospective students encounter an educational system without the capacity or vigor to meet their needs. Here discussed are some principles and proposals to allow universities, partnering with health-care providers, government agencies, and other stake-holders to develop new programs, or reenergize existing ones to serve our students and patients. Principles include academic rigor in biomedical and clinical science, multiple points of entry for students, flexibility in format, cost effectiveness, career ladders and robust partnerships.

Methodological proposal for occupational health and safety actions in research laboratories with nanotechnologies activities.  

PubMed

Nanotechnologies is a multidisciplinary set of techniques to manipulate matter on nanoscale level, more precisely particles below 100 nm whose characteristic due to small size is essentially different from those found in macro form materials. Regarding to these new properties of the materials there are knowledge gaps about the effects of these particles on human organism and the environment. Although it still being considered emerging technology it is growing increasingly fast as well as the number of products using nanotechnologies in some production level and so the number of researchers involved with the subject. Given this scenario and based on literature related, a comprehensive methodology for health and safety at work for researching laboratories with activities in nanotechnologies was developed, based on ILO structure guidelines for safety and health at work system on which a number of nanospecific recommendations were added to. The work intends to offer food for thought on controlling risks associated to nanotechnologies. PMID:22317200

System for laboratory proficiency testing in bacteriology: organisation and impact on microbiology laboratories in health care facilities funded by the Ontario Government.  

PubMed Central

The Ministry of Health requires that all medical laboratories in the Province of Ontario participate in a laboratory proficiency testing program (LPTP). In bacteriology compliance has been excellent. Eighty-six laboratories, for various reasons over the period under review, have surrendered their licence or, because of poor performance on LPTP test surveys, have had their licence withdrawn by the Ministry. The highest percentage of withdrawals occurred in small hospitals in isolated areas. In April 1979 there were 249 participating laboratories. Participants' results are first analysed by computer, and, subsequently, approximately 20% of participants' reports are reviewed by the Committee. Various Committee actions ensue: correspondence with the laboratory director regarding errors; an offer of a visit; and possibly a report via a senior LPTP committee to the Ministry that a laboratory is non-proficient and, in LPTP's terms of reference, non-remediable. Subsequent Ministry action might be the withdrawal of a laboratory's licence. However, this last recourse only occurs when educational efforts have proved ineffectual. Overall, performance in LPTP bacteriology surveys has improved over the period 1975-8, with 68% of 263 laboratories achieving a score of 70% or higher and 26% of 263 laboratories scoring less than 60%.

Ten-year Investigation of Clinical, Laboratory and Radiologic Manifestations and Complications in Patients with Takayasu's Arteritis in Three University Hospitals  

PubMed Central

Background: Takayasu arteritis is a condition of unknown aetiology that affects the aorta and its primary branches. The disease has been primarily recognized and described in Asia. The aims of this study were to identify the main clinical, laboratory, and angiographic features of Takayasu arteritis in Iranian patients over a 10 year period from 2000 to 2010. Methods: Data were obtained from angiographic and medical records of patients treated at Shahid-Rajai, Taleghani, and Loghman Hospitals during the above-mentioned time period. The criteria for definitions and findings were those proposed by the American College of Rheumatology. Results: A total of 15 patients were identified. The median age at presentation was 36 years and 73.3% of patients were females. Fever was the most common presentation. According to “modified” National Institute of Health criteria, 44.7% of patients were in the acute phase of disease with systemic symptoms such as fever, weight loss, and elevated C-reactive protein (CRP) levels. Immunological markers such as antinuclear antibodies (ANA) and antineutrophil cytoplasmic antibodies (C-ANCA) were absent. The tuberculin test result was positive in 40% of the patients. Vascular bruit was present in 86.7% and hypertension was detected in 53.3% with 13.3% having associated renal artery stenosis. The angiographic manifestations were classified as; type I, cervicobrachial type (26.6%); type II, thoracoabdominal type (20.0%); type III, peripheral type (6.6%); and type IV, generalised type (46.7%). Coronary arteries were involved in three cases, pulmonary in two and renal in two. Conclusion: Based on our findings, the most common clinical, laboratory and angiographic findings were fever, increased erythrocyte sedimentation rate (ESR) and stenosis, respectively. Because of dangerous consequences of this disease, attention to fever and increased ESR, especially in young women may be helpful for physicians to prevent diagnosis delay.

Health centres' view of the services provided by a university hospital laboratory: Use of satisfaction surveys  

PubMed Central

Customer orientation has gained increasing attention in healthcare. A customer satisfaction survey is one way to raise areas and topics for quality improvement. However, it seems that customer satisfaction surveys have not resulted in quality improvement in healthcare. This article reports how the authors' university hospital laboratory has used customer satisfaction surveys targeted at the health centres in their hospital district. Closed-ended statements of the questionnaire were planned to cover the essential aspects of laboratory services. In addition, an open-ended question asked what was considered to be the most important problem in services. The questionnaires were sent to the medical directors of the health centres. The open-ended question proved to be very useful because the responses specified the main problems in service. Based on the responses, selected dissatisfied customers were contacted to specify their responses and possible corrective actions were taken. It is concluded that a satisfaction survey can be used as a screening tool to identify topics of dissatisfaction. In addition, further clarifications with selected customers are needed to specify the causes for their dissatisfaction and to undertake proper corrective actions.

RadBall™ Technology Testing in the Savannah River Site's Health Physics Instrument Calibration Laboratory  

PubMed Central

The United Kingdom’s National Nuclear Laboratory (NNL) has developed a radiation-mapping device that can locate and quantify radioactive hazards within contaminated areas of the nuclear industry. The device, known as RadBall™, consists of a colander-like outer collimator that houses a radiation-sensitive polymer sphere. The collimator has over two hundred small holes; thus, specific areas of the polymer sphere are exposed to radiation becoming increasingly more opaque in proportion to the absorbed dose. The polymer sphere is imaged in an optical-CT scanner that produces a high resolution 3D map of optical attenuation coefficients. Subsequent analysis of the optical attenuation data provides information on the spatial distribution of sources in a given area forming a 3D characterization of the area of interest. The RadBall™ technology has been deployed in a number of technology trials in nuclear waste reprocessing plants at Sellafield in the United Kingdom and facilities of the Savannah River National Laboratory (SRNL). This paper summarizes the tests completed at SRNL Health Physics Instrument Calibration Laboratory (HPICL).

Radiology's value chain.  

PubMed

A diagnostic radiology value chain is constructed to define its main components, all of which are vulnerable to change, because digitization has caused disaggregation of the chain. Some components afford opportunities to improve productivity, some add value, while some face outsourcing to lower labor cost and to information technology substitutes, raising commoditization risks. Digital image information, because it can be competitive at smaller economies of scale, allows faster, differential rates of technological innovation of components, initiating a centralization-to-decentralization technology trend. Digitization, having triggered disaggregation of radiology's professional service model, may soon usher in an information business model. This means moving from a mind-set of "reading images" to an orientation of creating and organizing information for greater accuracy, faster speed, and lower cost in medical decision making. Information businesses view value chain investments differently than do small professional services. In the former model, producing a better business product will extend image interpretation beyond a radiologist's personal fund of knowledge to encompass expanding external imaging databases. A follow-on expansion with integration of image and molecular information into a report will offer new value in medical decision making. Improved interpretation plus new integration will enrich and diversify radiology's key service products, the report and consultation. A more robust, information-rich report derived from a "systems" and "computational" radiology approach will be facilitated by a transition from a professional service to an information business. Under health care reform, radiology will transition its emphasis from volume to greater value. Radiology's future brightens with the adoption of a philosophy of offering information rather than "reads" for decision making. Staunchly defending the status quo via turf wars is unlikely to constitute a forward-looking, competitive strategy. PMID:22438447

Radioactive Waste Management Complex low-level waste radiological performance assessment  

SciTech Connect

This report documents the projected radiological dose impacts associated with the disposal of radioactive low-level waste at the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory. This radiological performance assessment was conducted to evaluate compliance with applicable radiological criteria of the US Department of Energy and the US Environmental Protection Agency for protection of the public and the environment. The calculations involved modeling the transport of radionuclides from buried waste, to surface soil and subsurface media, and eventually to members of the public via air, groundwater, and food chain pathways. Projections of doses were made for both offsite receptors and individuals inadvertently intruding onto the site after closure. In addition, uncertainty and sensitivity analyses were performed. The results of the analyses indicate compliance with established radiological criteria and provide reasonable assurance that public health and safety will be protected.

Radiological operational scenario for a permanent lunar base  

NASA Astrophysics Data System (ADS)

An operational scenario for a lunar base is postulated based on 30 lunar base personnel and 2 year tours of duty plus stipulated numbers of EVA's and sorties in the lunar rover vehicles. It is also postulated that the main shielding material for the lunar base units (habitats, laboratories, etc.) will be lunar regolith. Using the solar minimum period as the basis, total accumulated dose equivalents for the galactic cosmic radiation over the two year period are computed at various shielding depths. Depths of regolith of over 20 g/sq cm are sufficient to reduce the total dose equivalents to well under the present limits. The second arm of the radiological health strategy -- continuous and all-encompassing radiation dosimetry -- is also discussed in some detail. It is also emphasized that monitoring of the base personnel for genetic mutations and chromosomal aberrations must be part of the radiological health program in the lunar base.

The effect of for-profit laboratories on the accountability, integration, and cost of Canadian health care services  

PubMed Central

Abstract Canadian public health care systems pay for-profit corporations to provide essential medical laboratory services. This practice is a useful window on the effects of using for-profit corporations to provide publicly funded services. Because private corporations are substantially protected by law from the public disclosure of “confidential business information,” increased for-profit delivery has led to decreased transparency, thus impeding informed debate on how laboratory services are delivered. Using for-profit laboratories increases the cost of diagnostic testing and hinders the integration of health care services more generally. Two useful steps toward ending the for-profit provision of laboratory services would be to stop fee-for-service funding and to integrate all laboratory work within public administrative structures.

Analysis of containment performance and radiological consequences under severe accident conditions for the Advanced Neutron Source Reactor at the Oak Ridge National Laboratory  

SciTech Connect

A severe accident study was conducted to evaluate conservatively scoped source terms and radiological consequences to support the Advanced Neutron Source (ANS) Conceptual Safety Analysis Report (CSAR). Three different types of severe accident scenarios were postulated with a view of evaluating conservatively scoped source terms. The first scenario evaluates maximum possible steaming loads and associated radionuclide transport, whereas the next scenario is geared towards evaluating conservative containment loads from releases of radionuclide vapors and aerosols with associated generation of combustible gases. The third scenario follows the prescriptions given by the 10 CFR 100 guidelines. It was included in the CSAR for demonstrating site-suitability characteristics of the ANS. Various containment configurations are considered for the study of thermal-hydraulic and radiological behaviors of the ANS containment. Severe accident mitigative design features such as the use of rupture disks were accounted for. This report describes the postulated severe accident scenarios, methodology for analysis, modeling assumptions, modeling of several severe accident phenomena, and evaluation of the resulting source term and radiological consequences.

Nest Building as an Indicator of Health and Welfare in Laboratory Mice  

PubMed Central

The minimization and alleviation of suffering has moral and scientific implications. In order to mitigate this negative experience one must be able to identify when an animal is actually in distress. Pain, illness, or distress cannot be managed if unrecognized. Evaluation of pain or illness typically involves the measurement of physiologic and behavioral indicators which are either invasive or not suitable for large scale assessment. The observation of nesting behavior shows promise as the basis of a species appropriate cage-side assessment tool for recognizing distress in mice. Here we demonstrate the utility of nest building behavior in laboratory mice as an ethologically relevant indicator of welfare. The methods presented can be successfully used to identify thermal stressors, aggressive cages, sickness, and pain. Observation of nest building behavior in mouse colonies provides a refinement to health and well-being assessment on a day to day basis.

A study of enteropathogenic organisms isolated in the public health laboratory, Lusaka.  

PubMed

A total of 328 specimens of stools were examined in the Public Health Laboratory during January and February 1973. Enteropathogens were isolated from 117 of these specimens. Besides these, 12 strains of Salmonellae were isolated from blood and 8 from urine. An occasional Salmonella was isolated from the pleural fluid (S. paratyphi A) pus from the knee (S. enteritidis) and from the C.S.F. of an infant (S. paratyphi C.). Salmonella typhi and Salmonella paratyphi A are the predominant Salmonella species. No Salmonella paratyphi B has been isolated. Shigella, was isolated with slightly less frequency than Salmonella, and Shigella flexneriis was the predominant species. E. coli 0112/K66 is the most common enteropathogenic E. coli. The majority of the Shigella and Salmonella species are sensitive to the common antibiotics used. The E. coli organisms show multiple resistance to a number of antibiotics. PMID:328771

Human-health effects of radium: an epidemiolgic perspective of research at Argonne National Laboratory  

SciTech Connect

The topic of health effects of radium has recently been considerably broadened by the identification of multiple myeloma as a specific outcome of bone-seeking radionuclides, and by evidence that the incidence of breast cancer may be significantly increased by radium exposure. All soft-tissue tumors are now suspect, especially leukemias. Concepts of dose-response need to be broadened to include the concept of risk factors, or, if one prefers, of susceptible subgroups. Biological factors relating to radium uptake and retention require study, as do risk factors modifying risk of both the clasical tumors, osteosarcoma and nasal sinus/mastoid, and the more recently suspect soft-tissue tumors. The history, organization, and current research activities in epidemiology at Argonne National Laboratory are described, and findings of the last decade and a half reviewed. Plans for future research are briefly discussed.

PubMed

Medical laboratory services are an essential, yet often neglected, component of health systems in developing countries. Their central role in public health, disease control and surveillance, and patient management is often poorly recognized by governments and donors. However, medical laboratory services in developing countries can be strengthened by leveraging funding from other sources of HIV/AIDS prevention, care, surveillance, and treatment programs. Strengthening these services will require coordinated efforts by national governments and partners and can be achieved by establishing and implementing national laboratory strategic plans and policies that integrate laboratory systems to combat major infectious diseases. These plans should take into account policy, legal, and regulatory frameworks; the administrative and technical management structure of the laboratories; human resources and retention strategies; laboratory quality management systems; monitoring and evaluation systems; procurement and maintenance of equipment; and laboratory infrastructure enhancement. Several countries have developed or are in the process of developing their laboratory plans, and others, such as Ethiopia, have implemented and evaluated their plan. PMID:19461093

Data mining in radiology  

PubMed Central

Data mining facilitates the study of radiology data in various dimensions. It converts large patient image and text datasets into useful information that helps in improving patient care and provides informative reports. Data mining technology analyzes data within the Radiology Information System and Hospital Information System using specialized software which assesses relationships and agreement in available information. By using similar data analysis tools, radiologists can make informed decisions and predict the future outcome of a particular imaging finding. Data, information and knowledge are the components of data mining. Classes, Clusters, Associations, Sequential patterns, Classification, Prediction and Decision tree are the various types of data mining. Data mining has the potential to make delivery of health care affordable and ensure that the best imaging practices are followed. It is a tool for academic research. Data mining is considered to be ethically neutral, however concerns regarding privacy and legality exists which need to be addressed to ensure success of data mining.

Surface radiological investigations at environmental research area 11, [sup 137]Cs- and [sup 60]Co-contaminated plots at Oak Ridge National Laboratory, Oak Ridge, Tennessee  

SciTech Connect

A surface radiological investigation at the [sup 137]Cs- and [sup 6O]Co-contaminated forest area (Chestnut Ridge east and west plots) was conducted from January 1992 through August 1992. Results of the survey revealed numerous spots and small areas of surface contamination that followed the original placement of feeders used for [sup 6O]Co- and [sup 137]Cs-labeled seeds in a 1969--1970 study. Surface gamma exposure rates reached 380 [mu]R/h at the east plot and 400 [mu]R/h at the west plot, but approximately one-half and one- third, respectively, of the identified anomalies did not exceed 39 [mu]R/h. Results of soil sample analyses demonstrated that [sup 137]Cs and [sup 6O]Co were responsible for the elevated radiation levels. Radionuclides were found below the surface at soil sample locations, in some cases at depths below 18 in. The same pattern of subsurface contamination may be present at other elevated surface spots at both plots. These survey results show that current radiological conditions at the site remain an environmental problem. Recommendations for corrective actions are included.

Chemical health risk assessment for hazardous and mixed waste management units at Lawrence Livermore National Laboratory  

SciTech Connect

The Lawrence Livermore National Laboratory (LLNL) operates three Hazardous Waste Management Facilities with 24 associated waste management units for the treatment and storage of hazardous and mixed wastes. These wastes are generated by research programs and support operations. The storage and treatment units are presently operated under interim status in accordance with the requirements of the US Envirorunental Protection Agency (US EPA) and the Department of Toxic Substances Control (DTSC), a division of the California Envirorunental Protection Agency (Cal/EPA). As required by the California Hazardous Waste Control Act and the Resource Conservation and Recovery Act (RCRA), LLNL ha s applied for a Part B permit to continue operating the storage and waste treatment facilities. As part of this permitting process, LLNL is required to conduct a health risk assessment (HRA) to examine the potential health impacts to the surrounding community from continued storage and treatment of hazardous and mixed wastes. analysis document presents the results of this risk assessment. An analysis of maximum credible chemical accidents is also included in Section 7.0. This HRA was prepared in accordance with procedures set forth by the California Air Pollution Control Officers Association (CAPCOA) Air Toxics Assessment Manual,'' CAPCOA guidelines for preparing risk assessments under the Air Toxic Hot Spots'' Act (AB 2588) and requirements of the US EPA. By following these procedures, this risk assessment presents a conservative analysis of a hypothetical Maximally Exposed Individual (MEI) using many worst-case assumptions that will not apply to an actual individual. As such, the risk estimates presented should be regarded as a worst-case estimate of any actual risk that may be present.

Hospital management of mass radiological casualties: reassessing exposures from contaminated victims of an exploded radiological dispersal device.  

PubMed

One of the key issues in the aftermath of an exploded radiological dispersal device from a terrorist event is that of the contaminated victim and the concern among healthcare providers for the harmful exposures they may receive in treating patients, especially if the patient has not been thoroughly decontaminated. This is critically important in the event of mass casualties from a nuclear or radiological incident because of the essential rapidity of acute medical decisions and that those who have life- or limb-threatening injuries may have treatment unduly delayed by a decontamination process that may be unnecessary for protecting the health and safety of the patient or the healthcare provider. To estimate potential contamination of those exposed in a radiological dispersal device event, results were used from explosive aerosolization tests of surrogate radionuclides detonated with high explosives at the Sandia National Laboratories. Computer modeling was also used to assess radiation dose rates to surgical personnel treating patients with blast injuries who are contaminated with any of a variety of common radionuclides. It is demonstrated that exceptional but plausible cases may require special precautions by the healthcare provider, even while managing life-threatening injuries of a contaminated victim from a radiological dispersal device event.

Battlefield radiology  

PubMed Central

With the increasing tempo of military conflicts in the last decade, much has been learnt about imaging battlefield casualties in the acute setting. Ultrasound in the form of focused abdominal sonography in trauma (FAST) has proven invaluable in emergency triage of patients for immediate surgery. Multidetector CT allows accurate determination of battlefield trauma injuries. It permits the surgeons and anaesthetists to plan their interventions more thoroughly and to be made aware of clinically occult injuries. There are common injury patterns associated with blast injury, gunshot wounds and blunt trauma. While this body of knowledge is most applicable to the battlefield, there are parallels with peacetime radiology, particularly in terrorist attacks and industrial accidents. This pictorial review is based on the experiences of a UK radiologist deployed in Afghanistan in 2010.

The power of hyphenated chromatography/time-of-flight mass spectrometry in public health laboratories.  

PubMed

Laboratories devoted to the public health field have to face the analysis of a large number of organic contaminants/residues in many different types of samples. Analytical techniques applied in this field are normally focused on quantification of a limited number of analytes. At present, most of these techniques are based on gas chromatography (GC) or liquid chromatography (LC) coupled to tandem mass spectrometry (MS/MS). Using these techniques only analyte-specific information is acquired, and many other compounds that might be present in the samples would be ignored. In this paper, we explore the potential of time-of-flight (TOF) MS hyphenated to GC or LC to provide additional information, highly useful in this field. Thus, all positives reported by standard reference targeted LC-MS/MS methods were unequivocally confirmed by LC-QTOF MS. Only 61% of positives reported by targeted GC-MS/MS could be confirmed by GC-TOF MS, which was due to its lower sensitivity as nonconfirmations corresponded to analytes that were present at very low concentrations. In addition, the use of TOF MS allowed searching for additional compounds in large-scope screening methodologies. In this way, different contaminants/residues not included in either LC or GC tandem MS analyses were detected. This was the case of the insecticide thiacloprid, the plant growth regulator paclobutrazol, the fungicide prochloraz, or the UV filter benzophenone, among others. Finally, elucidation of unknowns was another of the possibilities offered by TOF MS thanks to the accurate-mass full-acquisition data available when using this technique. PMID:22578112

[Revolution of the health care delivery system and its impacts on laboratory testing in the United States].  

PubMed

Failure to slow the exponential growth of total health care expenditures in the United States through the government policies resulted in a rapid and progressive penetration of managed care organizations(MCOs) in the early 1990s. Diagnostic testing is viewed as a "commodity" rather than a medical service under the managed care environment. Traditional hospital-based laboratories are placed in a downward spiral with the advent of managed care era. A massive reduction of in-house testing resulted from shorter lengths of patients' hospital stay and a marked decrease in admission under the dominance of managed care urges them to develop strategies for restoring tests deprived by the managed care-associated new businesses: consolidation and networking, participation in the outreach-testing market, and point-of-care/satellite laboratory testing in non-traditional, ambulatory settings are major strategies for survival of hospital laboratories. A number of physicians' office laboratories(POLs) have been closed owing to regulatory restrictions imposed by the Clinical Laboratory Improvement Amendments of 1988(CLIA '88), and to the expanded penetration of MCOs which limit reimbursement to a very few in-house procedures. It seems likely that POLs and hospital laboratories continue to reduce test volumes, while commercial reference laboratories(CRLs) gain more tests through contracting with MCOs. In the current stream of managed care dominance in the United States, clinical laboratories are changing their basic operation focus and mission in response to the aggressively changing landscape. Traditional laboratories which are unwilling to adapt themselves to the new environment will not survive in this country. PMID:10804811

Derivation of strontium-90 and cesium-137 residual radioactive material guidelines for the Laboratory for Energy-Related Health Research, University of California, Davis  

SciTech Connect

Residual radioactive material guidelines for strontium-90 and cesium-137 were derived for the Laboratory for Energy-Related Health Research (LEHR) site in Davis, California. The guideline derivation was based on a dose limit of 100 mrem/yr. The US Department of Energy (DOE) residual radioactive material guideline computer code, RESRAD, was used in this evaluation; this code implements the methodology described in the DOE manual for implementing residual radioactive material guidelines. Three potential site utilization scenarios were considered with the assumption that, for a period of 1,000 years following remedial action, the site will be utilized without radiological restrictions. The defined scenarios vary with regard to use of the site, time spent at the site, and sources of food consumed. The results of the evaluation indicate that the basic dose limit of 100 mrem/yr will not be exceeded within 1,000 years for either strontium-90 or cesium-137, provided that the soil concentrations of these radionuclides at the LEHR site do not exceed the following levels: 71,000 pCi/g for strontium-90 and 91 pCi/g for cesium-137 for Scenario A (researcher: the expected scenario); 160,000 pCi/g for strontium-90 and 220 pCi/g for cesium-137 for Scenario B (recreationist: a plausible scenario); and 37 pCi/g for strontium-90 and 32 pCi/g for cesium-137 for Scenario C (resident farmer ingesting food produced in the contaminated area: a plausible scenario). The derived guidelines are single-radionuclide guidelines and are linearly proportional to the dose limit used in the calculations. In setting the actual strontium-90 and cesium-137 guidelines for the LEHR site, DOE will apply the as low as reasonably achievable (ALARA) policy to the decision-making process, along with other factors such as whether a particular scenario is reasonable and appropriate.

Implementation of a Radiological Safety Coach program  

SciTech Connect

The Safe Sites of Colorado Radiological Safety program has implemented a Safety Coach position, responsible for mentoring workers and line management by providing effective on-the-job radiological skills training and explanation of the rational for radiological safety requirements. This position is significantly different from a traditional classroom instructor or a facility health physicist, and provides workers with a level of radiological safety guidance not routinely provided by typical training programs. Implementation of this position presents a challenge in providing effective instruction, requiring rapport with the radiological worker not typically developed in the routine radiological training environment. The value of this unique training is discussed in perspective with cost-savings through better radiological control. Measures of success were developed to quantify program performance and providing a realistic picture of the benefits of providing one-on-one or small group training. This paper provides a description of the unique features of the program, measures of success for the program, a formula for implementing this program at other facilities, and a strong argument for the success (or failure) of the program in a time of increased radiological safety emphasis and reduced radiological safety budgets.

Worker Safety and Health Issues Associated with the DOE Environmental Cleanup Program: Insights From the DOE Laboratory Directors' Environmental and Occupational/Public health Standards Steering Group  

SciTech Connect

The U.S. Department of Energy (DOE) Laboratory Directors' Environmental and Occupational/Public Health Standards Steering Group (or ''SSG'') was formed in 1990. It was felt then that ''risk'' could be an organizing principle for environmental cleanup and that risk-based cleanup standards could rationalize clean up work. The environmental remediation process puts workers engaged in cleanup activities at risk from hazardous materials and from the more usual hazards associated with construction activities. In a real sense, the site remediation process involves the transfer of a hypothetical risk to the environment and the public from isolated contamination into real risks to the workers engaged in the remediation activities. Late in its existence the SSG, primarily motivated by its LANL representative, Dr. Harry Ettinger, actively investigated issues associated with worker health and safety during environmental remediation activities. This paper summarizes the insights noted by the SSG. Most continue to be pertinent today.

Radiological assistance program: Region I. Part I  

SciTech Connect

The purpose of the Radiological Assistance Program (RAP) is to make DOE resources available and provide emergency assistance to state and local agencies in order to control radiological hazards, protect the public health and safety, and minimize the loss of property. This plan is an integral part of a nationwide program of radiological assistance established by the US DOE, and is implemented on a regional basis. The Brookhaven Area Office (BHO) Radiological Assistance Program is applicable to DOE Region I, which consists of the New England States, New York, New Jersey, Pennsylvania, Delaware, Maryland and the District of Columbia. The BHO RAP-1 has been developed to: (a) ensure the availability of an effective radiological assistance capability to ensure the protection of persons and property; (b) provide guidelines to RAP-1 Team personnel for the evaluation of radiological incidents and implementation of corrective actions; (c) maintain liaison with other DOE installations, Federal, State and local organizations which may become involved in radiological assistance operations in Region I; and (d) encourage development of a local capability to cope with radiological incidents.

Potential health hazards for students exposed to formaldehyde in the gross anatomy laboratory.  

PubMed

Formaldehyde, which has been a well-established preservative for cadavers in the anatomy laboratory for years, has an odor that many anatomy students find unpleasant. Anatomy faculty and students, embalmers in funeral homes, histopathology laboratory workers, and other biological researchers are continually exposed to the toxic vapors of formaldehyde. The immediate effects of that agent are nausea, headache, and ocular irritation that causes tear overflow and a burning sensation in the throat. Long-term exposure to formaldehyde can cause contact dermatitis, congenital defects, and cancer. This article discusses the adverse effects of continual exposure to formaldehyde and formalin and suggests various measures that can eliminate or minimize that danger to staff and students in gross anatomy laboratories.

Health hazard evaluation report HETA 84-419-1697, USGS Laboratory, Doraville, Georgia. [Benzene, methylene chloride, hexane, and acetone  

SciTech Connect

The U.S. Geological Survey National Water Quality Laboratory, Doraville, Georgia requested an evaluation of physical complaints reported by employees to determine possible work related causes. Laboratory workers, in general, complained of physical symptoms which were irritative (rash, sore throat, nose or sinus irritation), neurological (numbness, muscle weakness) and nonspecific (dizziness, headache, emotional swings, insomnia, muscle aching, fatigue). Reported exposure to solvents such as benzene, methylene chloride, hexane and acetone were positively related with light headedness or dizziness, numbness, unexplained muscle weakness and muscle aching. Air sampling did not reveal any remarkable exposure to chemical contaminants. The authors conclude that no relationship could be established between chemical exposures and antinuclear antibody positivity. Exposure to chemicals measured by air sampling were below occupational health exposure limits.

International Data on Radiological Sources  

SciTech Connect

ABSTRACT The mission of radiological dispersal device (RDD) nuclear forensics is to identify the provenance of nuclear and radiological materials used in RDDs and to aid law enforcement in tracking nuclear materials and routes. The application of databases to radiological forensics is to match RDD source material to a source model in the database, provide guidance regarding a possible second device, and aid the FBI by providing a short list of manufacturers and distributors, and ultimately to the last legal owner of the source. The Argonne/Idaho National Laboratory RDD attribution database is a powerful technical tool in radiological forensics. The database (1267 unique vendors) includes all sealed sources and a device registered in the U.S., is complemented by data from the IAEA Catalogue, and is supported by rigorous in-lab characterization of selected sealed sources regarding physical form, radiochemical composition, and age-dating profiles. Close working relationships with global partners in the commercial sealed sources industry provide invaluable technical information and expertise in the development of signature profiles. These profiles are critical to the down-selection of potential candidates in either pre- or post- event RDD attribution. The down-selection process includes a match between an interdicted (or detonated) source and a model in the database linked to one or more manufacturers and distributors.

Human health issues for plutonium inhalation: Perspectives from laboratory animal studies  

SciTech Connect

Since the first production of plutonium in the 1940s, potential health effects from plutonium have been a concern for humans. The few people exposed to plutonium and the relatively small intakes that have occurred, at least in the Western world, have resulted in very little direct information from human population studies. The Manhattan Project workers have been followed for decades, and few health effects have been observed. The situation is similar for the population of workers at the Rocky Flats facility. Some information is now being released from the former Soviet Union on selected worker populations who show biological effects, primarily pulmonary fibrosis and some increase in lung cancers.

Using a medical simulation center as an electronic health record usability laboratory.  

PubMed

Usability testing is increasingly being recognized as a way to increase the usability and safety of health information technology (HIT). Medical simulation centers can serve as testing environments for HIT usability studies. We integrated the quality assurance version of our emergency department (ED) electronic health record (EHR) into our medical simulation center and piloted a clinical care scenario in which emergency medicine resident physicians evaluated a simulated ED patient and documented electronically using the ED EHR. Meticulous planning and close collaboration with expert simulation staff was important for designing test scenarios, pilot testing, and running the sessions. Similarly, working with information systems teams was important for integration of the EHR. Electronic tools are needed to facilitate entry of fictitious clinical results while the simulation scenario is unfolding. EHRs can be successfully integrated into existing simulation centers, which may provide realistic environments for usability testing, training, and evaluation of human-computer interactions.

Medical surveillance can best be defined as conducting specific, targeted medical examinations at pre-determined intervals for the purpose of assessing whether individuals have suffered work-related illness or injury. The objectives of the medical examinations are to determine if there is any evidence of illness or injury and to determine whether any illness or injury found is occupationally related. If illness or injury is found, the employee under medical surveillance can be referred for immediate treatment. Other employees in the same work group can be examined, and any hazardous defects in the workplace can be corrected. Additional objectives of these periodic examinations are to determine whether the employee`s health status and physical fitness continue to be compatible with the safe performance of his assigned job tasks; to contribute to employee health maintenance by providing the opportunity for early detection, treatment, and prevention of disease or injuries; and to provide a documented record status that can be used in analysis of the health of the work group as a whole.

The public health laboratory service (PHLS) and its role in the control of zoonotic disease.  

PubMed

The aetiology of zoonotic infections embraces organisms from every branch of the microbial world. In addition, zoonoses must be considered as a truly global problem, both in terms of their distribution and the measures required for their control. Within the UK, zoonotic disease is considered to be less frequent than in some less developed parts of the world. However, its contribution to overall morbidity and mortality within the UK population is not well established. In an attempt to define the impact of zoonotic infection more accurately, a multicentre prospective study of disease in farmers in England and Wales was initiated by the PHLS in 1992. The study involved the completion by participants of annual questionnaires dealing with their own health and the range and health of their livestock. Our results confirmed that some infections occur frequently in farmers. For example, ringworm and Q fever were associated with contact with cattle and orf with the handling of sheep. Some findings were unexpected; the incidence and prevalence of leptospirosis, for example, were far lower in the farmers than had been anticipated, whilst there was a higher than expected incidence and prevalence of hantavirus infection. The success of the project was largely due to the adoption of a multidisciplinary approach and the continuity of funding which enabled the study of the same cohort to continue for 7 years.

Improved clinical and laboratory skills after team-based, malaria case management training of health care professionals in Uganda  

PubMed Central

Background Deployment of highly effective artemisinin-based combination therapy for treating uncomplicated malaria calls for better targeting of malaria treatment to improve case management and minimize drug pressure for selecting resistant parasites. The Integrated Management of Malaria curriculum was developed to train multi-disciplinary teams of clinical, laboratory and health information assistants. Methods Evaluation of training was conducted in nine health facilities that were Uganda Malaria Surveillance Programme (UMSP) sites. From December 2006 to June 2007, 194 health professionals attended a six-day course. One-hundred and one of 118 (86%) clinicians were observed during patient encounters by expert clinicians at baseline and during three follow-up visits approximately six weeks, 12 weeks and one year after the course. Experts used a standardized tool for children less than five years of age and similar tool for patients five or more years of age. Seventeen of 30 laboratory professionals (57%) were assessed for preparation of malaria blood smears and ability to interpret smear results of 30 quality control slides. Results Percentage of patients at baseline and first follow-up, respectively, with proper history-taking was 21% and 43%, thorough physical examination 18% and 56%, correct diagnosis 51% and 98%, treatment in compliance with national policy 42% and 86%, and appropriate patient education 17% and 83%. In estimates that adjusted for individual effects and a matched sample, relative risks were 1.86 (95% CI: 1.20,2.88) for history-taking, 2.66 (95%CI: 1.60,4.41) for physical examination, 1.77 (95%CI: 1.41,2.23) for diagnosis, 1.96 (95%CI: 1.46,2.63) for treatment, and 4.47 (95%CI: 2.68,7.46) for patient education. Results were similar for subsequent follow-up and in sub-samples stratified by patient age. Quality of malaria blood smear preparation improved from 21.6% at baseline to 67.3% at first follow-up (p < 0.008); sensitivity of interpretation of quality control slides increased from 48.6% to 70.6% (p < 0.199) and specificity increased from 72.1% to 77.2% (p < 0.736). Results were similar for subsequent follow-up, with the exception of a significant increase in specificity (94.2%, p < 0.036) at one year. Conclusion A multi-disciplinary team training resulted in statistically significant improvements in clinical and laboratory skills. As a joint programme, the effects cannot be distinguished from UMSP activities, but lend support to long-term, on-going capacity-building and surveillance interventions.

Environmental health-risk assessment for tritium releases from the National Tritium Labeling Facility (NTLF) at Lawrence Berkeley Laboratory  

SciTech Connect

This report is a health risk assessment that addresses continuous releases of tritium to the environment from the National Tritium Labeling Facility (NTLF) at the Lawrence Berkeley Laboratory (LBL). The NTLF contributes approximately 95% of all tritium releases from LBL. Transport and transformation models were used to determine the movement of tritium releases from the NRLF to the air, surface water, soils, and plants and to determine the subsequent doses to humans. These models were calibrated against environmental measurements of tritium levels in the vicinity of the NTLF and in the surrounding community. Risk levels were determined for human populations in each of these zones. Risk levels to both individuals and populations were calculated. In this report population risks and individual risks were calculated for three types of diseases--cancer, heritable genetic effects, and developmental and reproductive effects.

Changes, disruption and innovation: An investigation of the introduction of new health information technology in a microbiology laboratory  

PubMed Central

Background: It is expected that health information technology (HIT) will deliver a safer, more efficient and effective health care system. The aim of this study was to undertake a qualitative and video-ethnographic examination of the impact of information technologies on work processes in the reception area of a Microbiology Department, to ascertain what changed, how it changed and the impact of the change. Materials and Methods: The setting for this study was the microbiology laboratory of a large tertiary hospital in Sydney. The study consisted of qualitative (interview and focus group) data and observation sessions for the period August 2005 to October 2006 along with video footage shot in three sessions covering the original system and the two stages of the Cerner implementation. Data analysis was assisted by NVivo software and process maps were produced from the video footage. Results: There were two laboratory information systems observed in the video footage with computerized provider order entry introduced four months later. Process maps highlighted the large number of pre data entry steps with the original system whilst the newer system incorporated many of these steps in to the data entry stage. However, any time saved with the new system was offset by the requirement to complete some data entry of patient information not previously required. Other changes noted included the change of responsibilities for the reception staff and the physical changes required to accommodate the increased activity around the data entry area. Conclusions: Implementing a new HIT is always an exciting time for any environment but ensuring that the implementation goes smoothly and with minimal trouble requires the administrator and their team to plan well in advance for staff training, physical layout and possible staff resource reallocation.

In this paper, we give a short introduction to machine learning and survey its applications in radiology. We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, and text analysis of radiology reports using natural language processing (NLP) and natural language understanding (NLU). This survey shows that machine learning plays a key role in many radiology applications. Machine learning identifies complex patterns automatically and helps radiologists make intelligent decisions on radiology data such as conventional radiographs, CT, MRI, and PET images and radiology reports. In many applications, the performance of machine learning-based automatic detection and diagnosis systems has shown to be comparable to that of a well-trained and experienced radiologist. Technology development in machine learning and radiology will benefit from each other in the long run. Key contributions and common characteristics of machine learning techniques in radiology are discussed.

Evaluation of individually ventilated cage systems for laboratory rodents: cage environment and animal health aspects.  

PubMed

The use of individually ventilated cage (IVC) systems has become an attractive housing regime of laboratory rodents. The benefits of IVC systems are, reportedly, a high degree of containment combined with relative ease of handling, and a high degree of protection from allergenes. In the present study we tested whether two IVC systems (BioZone VentiRack, IVC1 and Techniplast SealSafe, IVC2S), in which we held mature male NMRI mice, were constructed to maintain a constant differential pressure, positive or negative, during a prolonged period of time. We also measured ammonia (NH3) concentrations after about 2 weeks of use, and CO2 build-up during a 60 min simulated power failure situation. In addition, animal weight development and bite-wound frequency were recorded (Renström et al. 2000). From the present study it is concluded that the IVC1 air handling system provides a more uniform and balanced differential pressure than the IVC2S. Both systems effectively scavenge NH3 when bedding material is not soaked by urine. Although the IVCs are dependent on the continual function of the fans to work properly, it seems unlikely that CO2 concentrations increase to hazardous levels, as a result of a one hour power failure, with the type of cages used in this study. Differences in weight development and bite-wound occurrence were noted between the two IVC systems. Causes for these differences could not be established and need more investigation. PMID:11201288

This human health risk assessment has been prepared for the Environmental Restoration (ER) Program at the Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee. The objectives of this risk assessment are to evaluate the alternatives for interim closure of the Building 3001 Storage Canal and to identify the potential health risk from an existing leak in the canal. The Building 3001 Storage Canal connects Buildings 3001 and 3019. The volume of water in the canal is monitored and kept constant at about 62,000 gal. The primary contaminants of the canal water are the radionuclides {sup 137}Cs, {sup 60}Co, and {sup 90}Sr; a layer of sediment on the canal floor also contains radionuclides and metals. The prime medium of contaminant transport has been identified as groundwater. The primary route for occupational exposure at the canal is external exposure to gamma radiation from the canal water and the walls of the canal. Similarly, the primary exposure route at the 3042 sump is external exposure to gamma radiation from the groundwater and the walls of the sump. Based on the exposure rates in the radiation work permits (Appendix C) and assuming conservative occupational work periods, the annual radiation dose to workers is considerably less than the relevant dose limits. The potential risk to the public using the Clinch River was determined for three significant exposure pathways: ingestion of drinking water; ingestion of contaminated fish; and external exposure to contaminated sediments on the shoreline, the dominant exposure pathway.

Buprenorphine/Naloxone and Methadone Effects on Laboratory Indices of Liver Health: a Randomized Trial  

PubMed Central

BACKGROUND Buprenorphine/naloxone (BUP) and methadone (MET) are efficacious treatments for opioid dependence, although concerns about a link between BUP and drug-induced hepatitis have been raised. This study compares the effects of BUP and MET on liver health in opioid-dependent participants. METHODS This was a randomized controlled trial of 1269 opioid-dependent participants seeking treatment at 8 federally licensed opioid treatment programs and followed for up to 32 weeks between May 2006 and August 2010; 731 participants met “evaluable” criteria defined as completing 24 weeks of medication and providing at least 4 blood samples for transaminase testing. Participants were randomly assigned to receive BUP or MET for 24 weeks. Shift table analysis determined how many evaluable participants moved between categories of low and elevated transaminase levels. Predictors of moving from low to high transaminase levels were identified. RESULTS Changes in transaminase levels did not differ by medication condition. Baseline infection with hepatitis C or B was the only significant predictor of moving from low to elevated transaminase levels; 9 BUP and 15 MET participants showed extreme liver test elevations and were more likely than those without extreme elevations to have seroconverted to both hepatitis B and C during the study, or to use illicit drugs during the first 8 weeks of treatment. MET participants were retained longer in treatment than BUP participants. CONCLUSIONS This study demonstrated no evidence of liver damage during the initial 6 months of treatment in either condition. Physicians can prescribe either medication without major concern for liver injury.

Results of the Radiological Survey at Conviber, Inc., 644 Garfield Street, Springdale, Pennsylvania (CVP001)  

SciTech Connect

As part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), the US Department of Energy (DOE) is implementing a radiological survey program to determine the radiological conditions at sites that were used by the department`s predecessor agencies. During the mid-1940s, and possibly continuing until 1951, the Conviber site in Springdale, Pennsylvania, was used to machine extruded uranium in support of government efforts. In 1980 a radiological scanning survey of this site was conducted by DOE and Argonne National Laboratory (ANL) staffs. Their report noted one anomaly: elevated radiation levels over a small area inside the building where uranium had been machined. Because much of the floor was inaccessible, for surveying and because of the lack of definitive records documenting use of this site, a comprehensive radiological assessment was recommended. The radiological survey discussed in this report for the site of Conviber, Inc., Springdale, Pennsylvania, was conducted by members of the Measurement Applications and Development Group of Oak Ridge National Laboratory in June of 1989. The survey included a surface gamma scan, collection of concrete and soil samples, and measurement of direct and removable alpha and beta-gamma contamination. One indoor location with a gamma measurement of 20 {mu}R/h was found. In June of 1990 ORNL staff returned to investigate the location with elevated gamma. A hole was drilled through the concrete, gamma measurements were taken, and soil samples were obtained for analyses. In these eight indoor soil samples, concentrations of {sup 238}U ranged from 90 to 20,000 pCi/g. However, under current site use, residual uranium covered by concrete does not pose a health risk.

Accelerators in our past, present, and future: A challenge to radiological protection in the twenty-first century  

SciTech Connect

The foundations of many of the subdisciplines of radiological protection laid in accelerator laboratories began with the invention of accelerators. This paper suggests that the discipline of accelerator radiological protection has played and will continue play a more significant part in our lives than is generally recognized. A brief review of some existing uses of accelerators by society is given, and a few probable future uses are described. These future applications will result in the exposure of accelerator (or {open_quotes}mixed{close_quotes}) radiation fields to an increased population. Consequently, what are perceived to be the rather specialized concerns of today`s accelerator health physicists will -- by necessity -- become of general interest to all health physicists.

Chemical health risk assessment for hazardous and mixed waste management units at Lawrence Livermore National Laboratory. Volume 1  

SciTech Connect

The Lawrence Livermore National Laboratory (LLNL) operates three Hazardous Waste Management Facilities with 24 associated waste management units for the treatment and storage of hazardous and mixed wastes. These wastes are generated by research programs and support operations. The storage and treatment units are presently operated under interim status in accordance with the requirements of the US Envirorunental Protection Agency (US EPA) and the Department of Toxic Substances Control (DTSC), a division of the California Envirorunental Protection Agency (Cal/EPA). As required by the California Hazardous Waste Control Act and the Resource Conservation and Recovery Act (RCRA), LLNL ha s applied for a Part B permit to continue operating the storage and waste treatment facilities. As part of this permitting process, LLNL is required to conduct a health risk assessment (HRA) to examine the potential health impacts to the surrounding community from continued storage and treatment of hazardous and mixed wastes. analysis document presents the results of this risk assessment. An analysis of maximum credible chemical accidents is also included in Section 7.0. This HRA was prepared in accordance with procedures set forth by the California Air Pollution Control Officers Association (CAPCOA) ``Air Toxics Assessment Manual,`` CAPCOA guidelines for preparing risk assessments under the Air Toxic ``Hot Spots`` Act (AB 2588) and requirements of the US EPA. By following these procedures, this risk assessment presents a conservative analysis of a hypothetical Maximally Exposed Individual (MEI) using many worst-case assumptions that will not apply to an actual individual. As such, the risk estimates presented should be regarded as a worst-case estimate of any actual risk that may be present.

Comparison of the radiological and chemical toxicity of lead  

SciTech Connect

This report estimates the worst-case radiological dose to an individual from ingested lead containing picocurie levels of radionuclides and then compares the calculated radiological health effects to the chemical toxic effects from that same lead. This comparison provides an estimate of the consequences of inadvertently recycling, in the commercial market, lead containing nominally undetectable concentrations of radionuclides. Quantitative expressions for the radiological and chemical toxicities of lead are based on concentrations of lead in the blood stream. The result shows that the chemical toxicity of lead is a greater health hazard, by orders of magnitude, than any probable companion radiation dose.

[Distribution of intestinal parasites detected in the Tokat public health laboratory during the period from January 2007 - December 2009].  

PubMed

In this study, the results of 1868 stool samples and 215 cellophane tapes examined in the Tokat Public Health Laboratory between January 2007-December 2009 and the distribution of these parasites were evaluated retrospectively. A total of 1868 stool specimens from 1146 (61.3%) males and 722 (38.7%) females were examined for intestinal parasites using direct examination and the formol-ethyl acetate concentration methods. Intestinal parasites were found in 40 (2.1%) females and 85 (4.6%) males. A total of 215 cellophane tape specimens from 86 (40%) females and 129 (60%) males were examined. Parasites were detected in 6 (2.8%) female and 11 (5.1%) male patients. The distribution of intestinal parasites detected in stool specimens was as follows: 52 (2.8%) Giardia intestinalis, 15 (0.8%) Entamoeba histolytica/dispar, 46 (2.5%) Entamoeba coli, 2 (0.1%) Hymenolepis nana, 16 (0.9%) Taenia saginata, 3 (0.2%) Ascaris lumbricoides, and 1 (0.05%) Trichuris trichiura. Parasites detected in cellophane tape specimens included 17 (7.9%) Enterobius vermicularis and 3 (1.4%) Taenia saginata. Despite being labor-intensive, parasitological examination of stool samples with necessary staining methods by experienced staff will surely help to determine both the diagnosis and exact prevalence of intestinal parasitic infections in Turkey.

Emergency Response Planning for Radiological Releases  

SciTech Connect

The emergency management planning tool RISK-RDD was developed to aid emergency response planners and decision makers at all levels of government to better understand and prepare for potential problems related to a radiological release, especially those in urban areas. Radioactive release scenarios were studied by using the RISK-RDD radiological emergency management program. The scenarios were selected to investigate the key aspects of radiological risk management not always considered in emergency planning as a whole. These aspects include the evaluation of both aerosolized and non-aerosolized components of an atmospheric release, methods of release, acute and chronic human health risks, and the concomitant economic impacts as a function of the risk-based cleanup level.

Antimicrobial resistance and antimicrobial use associated with laboratory-confirmed cases of Campylobacter infection in two health units in Ontario  

PubMed Central

AIM: A population-based study was conducted over a two-year period in the Perth District (PD) and Wellington-Dufferin-Guelph (WDG) health units in Ontario to document antimicrobial resistance and antimicrobial use associated with clinical cases of laboratory-confirmed campylobacteriosis. METHODS: Etest (bioMérieux SA, France) was used to determine the minimum inhibitory concentration of amoxicillin/clavulanic acid, ampicillin, chloramphenicol, ciprofloxacin (CIP), clindamycin, erythromycin (ERY), gentamicin, nalidixic acid and tetracycline. Data regarding antimicrobial use were collected from 250 cases. RESULTS: Of the 250 cases, 165 (65.7%) reported staying home or being hospitalized due to campylobacteriosis. Fifty-four per cent of cases (135 of 249) reported taking antimicrobials to treat campylobacteriosis. In 115 cases (51.1%), fecal culture results were not used for treatment decisions because they were not available before the initiation of antimicrobial treatment and/or they were not available before the cessation of symptoms. Of the 250 cases, 124 (49.6%) had available Campylobacter isolates, of which 66 (53.2%) were resistant to at least one of the antimicrobials tested. No resistance to ampicillin, chloramphenicol or gentamicin was found in these isolates. Six isolates (4.8%) were resistant to CIP. Two isolates (1.6%) were resistant to ERY; however, no isolates were resistant to both CIP and ERY. CONCLUSION: Prudent use practices should be promoted among physicians to reduce the use of antimicrobials for the treatment of gastroenteritis in general and campylobacteriosis in particular, as well as to minimize the future development of resistance to these antimicrobials in Campylobacter species.

Towards filmless and distance radiology.  

PubMed

To many people radiology is synonymous with films. For 20 years or so, however, it has been possible to capture digitally data traditionally displayed on film, and that was true from the beginning of computed tomography and magnetic resonance imaging too. There is more to picture archiving and communication systems (PACS) than the economies of filmlessness and the ability to modify images. To realise the full potential of PACS requires huge and expensively equipped networks linking the radiology department, hospital wards, outpatient clinics, laboratories, family doctors' clinics, and so on, permitting simultaneous consultations on different sites and almost instant reporting from specialist radiologists at a distance. The data sets that need to be transferred are huge but some of the technical obstacles are now being overcome and the past few years have seen some hospitals move to a filmless state. The more common pattern, though, will be a piecemeal approach. PACS and teleradiology certainly provide a quicker imaging service. How soon a total PACS will save money for a hospital operating budget is less clear. PMID:9288061

Radiation dose assessments to support evaluations of radiological control levels for recycling or reuse of materials and equipment  

SciTech Connect

Pacific Northwest Laboratory is providing Environmental Protection Support and Assistance to the USDOE, Office of Environmental Guidance. Air, Water, and Radiation Division. As part of this effort, PNL is collecting data and conducting technical evaluations to support DOE analyses of the feasibility of developing radiological control levels for recycling or reuse of metals, concrete, or equipment containing residual radioactive contamination from DOE operations. The radiological control levels will be risk-based, as developed through a radiation exposure scenario and pathway analysis. The analysis will include evaluation of relevant radionuclides, potential mechanisms of exposure, and both health and non-health-related impacts. The main objective of this report is to develop a methodology for establishing radiological control levels for recycle or reuse. This report provides the results of the radiation exposure scenario and pathway analyses for 42 key radionuclides generated during DOE operations that may be contained in metals or equipment considered for either recycling or reuse. The scenarios and information developed by the IAEA. Application of Exemption Principles to the Recycle and Reuse of Materials from Nuclear Facilities, are used as the initial basis for this study. The analyses were performed for both selected worker populations at metal smelters and for the public downwind of a smelter facility. Doses to the public downwind were estimated using the US (EPA) CAP88-PC computer code with generic data on atmospheric dispersion and population density. Potential non-health-related effects of residual activity on electronics and on film were also analyzed.

The RAP is designed to make DOE resources available to other DOE facilities, state, tribal, local, private businesses, and individuals for the explicit purpose of assisting during radiological incidents. The DOE has an obligation, through the Atomic Energy Act of 1954, as amended, to provide resources through the Federal Radiological Emergency Response Plan (FRERP, Nov. 1985) in the event of a radiological incident. Toward this end, the RAP program is implemented on a regional basis, and has planned for an incremental response capability with regional coordination between states and DOE response elements. This regional coordination is intended to foster a working relationship between DOE radiological assistance elements and those state, tribal, and local agencies responsible for first response to protect public health and safety.

Ames Laboratory annual site environmental report, calendar year 1996  

SciTech Connect

This report summarizes the environmental status of Ames Laboratory for calendar year 1996. It includes descriptions of the Laboratory site, its mission, the status of its compliance with applicable environmental regulations, its planning and activities to maintain compliance, and a comprehensive review of its environmental protection, surveillance and monitoring programs. Ames Laboratory is located on the campus of Iowa State University (ISU) and occupies twelve buildings owned by the Department of Energy (DOE). The Laboratory also leases space in ISU owned buildings. Laboratory activities involve less than ten percent of the total chemical use and approximately one percent of the radioisotope use on the ISU campus. In 1996, the Office of Assurance and Assessment merged with the Environment, Safety and Health Group forming the Environment, Safety, Health and Assurance (ESH and A) office. In 1996, the Laboratory accumulated and disposed of wastes under US Environmental Protection Agency (EPA) issued generator numbers. Ames Laboratory submitted a Proposed Site Treatment Plan to EPA in December 1995. This plan complied with the Federal Facilities Compliance Act (FFCA). It was approved by EPA in January 1996. The consent agreement/consent order was issued in February 1996. Pollution awareness, waste minimization and recycling programs, implemented in 1990 and updated in 1994, continued through 1996. Included in these efforts were a waste white paper and green computer paper recycling program. Ames Laboratory also continued to recycle salvageable metal and used oil, and it recovered freon for recycling. All of the chemical and nearly all of the radiological legacy wastes were properly disposed by the end of 1996. Additional radiological legacy waste will be properly disposed during 1997.

A TWO-STAGE MODEL OF RADIOLOGICAL INSPECTION: SPENDING TIME  

SciTech Connect

The paper describes a model that visually portrays radiological survey performance as basic parameters (surveyor efficiency and criteria, duration of pause, and probe speed) are varied; field and laboratory tests provided typical parameter values. The model is used to illustrate how practical constraints on the time allotted to the task can affect radiological inspection performance. Similar analyses are applicable to a variety of other tasks (airport baggage inspection, and certain types of non-destructive testing) with similar characteristics and constraints.

Organizational decentralization in radiology.  

PubMed

At present, most hospitals have a department of radiology where images are captured and interpreted. Decentralization is the opposite of centralization and means 'away from the centre'. With a Picture Archiving and Communication System (PACS) and broadband communications, transmitting radiology images between sites will be far easier than before. Qualitative interviews of 26 resource persons were performed in Norway. There was a response rate of 90%. Decentralization of radiology interpretations seems less relevant than centralization, but several forms of decentralization have a role to play. The respondents mentioned several advantages, including exploitation of capacity and competence. They also mentioned several disadvantages, including splitting professional communities and reduced contact between radiologists and clinicians. With the new technology decentralization and centralization of image interpretation are important possibilities in organizational change. This will be important for the future of teleradiology.

Radiological Dispersion Devices and Basic Radiation Science  

NASA Astrophysics Data System (ADS)

Introductory physics courses present the basic concepts of radioactivity and an overview of nuclear physics that emphasizes the basic decay relationship and the various types of emitted radiation. Although this presentation provides insight into radiological science, it often fails to interest students to explore these concepts in a more rigorous manner. One reason for limited student interest is the failure to link the discussion to topics of current interest. The author has found that presenting this material with a link to radiological dispersion devices (RDDs), or dirty bombs, and their associated health effects provides added motivation for students. The events of Sept. 11, 2001, and periodic media focus on RDDs heighten student interest from both a scientific curiosity as well as a personal protection perspective. This article presents a framework for a more interesting discussion of the basics of radiation science and their associated health effects. The presentation can be integrated with existing radioactivity lectures or added as a supplementary or enrichment activity.

Surface radiological investigations at environmental research area 11, {sup 137}Cs- and {sup 60}Co-contaminated plots at Oak Ridge National Laboratory, Oak Ridge, Tennessee. Environmental Restoration Program  

SciTech Connect

A surface radiological investigation at the {sup 137}Cs- and {sup 6O}Co-contaminated forest area (Chestnut Ridge east and west plots) was conducted from January 1992 through August 1992. Results of the survey revealed numerous spots and small areas of surface contamination that followed the original placement of feeders used for {sup 6O}Co- and {sup 137}Cs-labeled seeds in a 1969--1970 study. Surface gamma exposure rates reached 380 {mu}R/h at the east plot and 400 {mu}R/h at the west plot, but approximately one-half and one- third, respectively, of the identified anomalies did not exceed 39 {mu}R/h. Results of soil sample analyses demonstrated that {sup 137}Cs and {sup 6O}Co were responsible for the elevated radiation levels. Radionuclides were found below the surface at soil sample locations, in some cases at depths below 18 in. The same pattern of subsurface contamination may be present at other elevated surface spots at both plots. These survey results show that current radiological conditions at the site remain an environmental problem. Recommendations for corrective actions are included.

Airborne radiological sampling of Mount St. Helens plumes  

SciTech Connect

Particulate and gaseous samples for radiologial analyses were collected from the plumes created by eruptions of Mount St. Helens. The sampling aircraft and equipment used are routinely employed in aerial radiological surveillance at the Nevada Test Site by the Environmental Protection Agency's Environmental Monitoring Systems Laboratory in Las Vegas, Nevada. An initial sample set was collected on April 4, 1980, during the period of recurring minor eruptions. Samples were collected again on May 19 and 20 following the major eruption of May 18. The Environmental Protection Agency's Office of Radiation Programs analyzed the samples for uranium and thorium isotopes, radium-226, lead-210, polonium-210, and radon-222. Other laboratories analyzed samples to determine particle size distribution and elemental composition. The only samples containing radioactivity above normal ambient levels were collected on May 20. Polonium-210 concentrations in the plume, determined from a sample collected between 5 and 30 km from the crater, were approximately an order of magnitude above background. Radon-222 concentrations in samples collected from the plume centerline at a distance of 15 km averaged approximately four times the average surface concentrations. The small increases in radioactivity would cause no observable adverse health effects.

Public health consequences among first responders to emergency events associated with illicit methamphetamine laboratories--selected states, 1996-1999.  

PubMed

Methamphetamine, a central nervous system stimulant, is manufactured in illicit laboratories using over-the-counter ingredients. Many of these ingredients are hazardous substances that when released from active or abandoned methamphetamine laboratories can place first responders at risk for serious injuries and death. In 16 states, the Agency for Toxic Substances and Disease Registry maintains the Hazardous Substances Emergency Events Surveillance (HSEES) system to collect and analyze data about the morbidity and mortality associated with hazardous substance-release events. Based on events reported to HSEES during 1996-1999, this report describes examples of events associated with illicit methamphetamine laboratories that resulted in injuries to first responders in three states, summarizes methamphetamine-laboratory events involving injured first responders, and suggests injury prevention methods to protect first responders.

Impact of the London 2012 Olympic and Paralympic Games on demand for microbiology gastrointestinal diagnostic services at the Public Health Laboratory London.  

PubMed

Planning for the London 2012 Olympic and Paralympic Games at the Public Health Laboratory London was based on the requirement to meet potential increased demand with scalable capacity. The aim of this study was to determine the impact on demand for microbiology gastrointestinal diagnostic services during the Games period. Retrospective cross-sectional time-series data analysis was used to assess the number of gastrointestinal specimens received in the laboratory and the number of positive results. There was no increase in the number of gastrointestinal specimens received during the Games period, thus the Games had no impact on demand for microbiology gastrointestinal diagnostic services at the laboratory. There was a decrease in the number of public health specimens received for culture [incidence rate ratio?=?0.34, 95?% confidence interval (CI)?=?0.13-0.86, P?=?0.02] and a decrease in the number of culture positive community specimens (odds ratio?=?0.59, 95?% CI?=?0.40-0.85, P?=?0.005), suggesting a decrease in gastrointestinal illness during the Games period. As previous planning assumptions were not based on actual specimen activity, the results of this study may modify the extent of additional planning for microbiological services required for mass gatherings.

Medical treatment of radiological casualties: current concepts.  

PubMed

The threat of radiologic or nuclear terrorism is increasing, yet many physicians are unfamiliar with basic treatment principles for radiologic casualties. Patients may present for care after a covert radiation exposure, requiring an elevated level of suspicion by the physician. Traditional medical and surgical triage criteria should always take precedence over radiation exposure management or decontamination. External contamination from a radioactive cloud is easily evaluated using a simple Geiger-Muller counter and decontamination accomplished by prompt removal of clothing and traditional showering. Management of surgical conditions in the presence of persistent radioactive contamination should be dealt with in a conventional manner with health physics guidance. To be most effective in the medical management of a terrorist event involving high-level radiation, physicians should understand basic manifestations of the acute radiation syndrome, the available medical countermeasures, and the psychosocial implications of radiation incidents. Health policy considerations include stockpiling strategies, effective use of risk communications, and decisionmaking for shelter-in-place versus evacuation after a radiologic incident.

A Low-Cost, Real-Time Network for Radiological Monitoring Around Nuclear Facilities  

SciTech Connect

A low-cost, real-time radiological sensor network for emergency response has been developed and deployed at the Lawrence Livermore National Laboratory (LLNL). The Real-Time Radiological Area Monitoring (RTRAM) network is comprised of 16 Geiger-Mueller (GM) sensors positioned on the site perimeter to continuously monitor radiological conditions as part of LLNL's comprehensive environment/safety/health protection program. The RTRAM network sensor locations coincide with wind sector directions to provide thorough coverage of the one square mile site. These low-power sensors transmit measurement data back to a central command center (CCC) computer through the LLNL telecommunications infrastructure. Alarm conditions are identified by comparing current data to predetermined threshold parameters and are validated by comparison with plausible dispersion modeling scenarios and prevailing meteorological conditions. Emergency response personnel are notified of alarm conditions by automatic radio- and computer- based notifications. A secure intranet provides emergency response personnel with current condition assessment data that enable them to direct field response efforts remotely. This system provides a low-cost real-time radiation monitoring solution that is easily converted to incorporate both a hard-wired interior perimeter with strategically positioned wireless secondary and tertiary concentric remote locations. These wireless stations would be configured with solar voltaic panels that provide current to recharge batteries and power the sensors and radio transceivers. These platforms would supply data transmission at a range of up to 95 km from a single transceiver location. As necessary, using radio transceivers in repeater mode can extend the transmission range. The RTRAM network as it is presently configured at LLNL has proven to be a reliable system since initial deployment in August 2001 and maintains stability during inclement weather conditions. With the proposed reconfiguration to a combined hard-wired and wireless network, which incorporates a robust server and modeling software, the system would be a durable and economical radiological monitoring system for nuclear power plants around the world.

Demystifying radiology information systems.  

PubMed

Selecting the right radiology information system (RIS) can be a difficult and tedious task for radiology managers. Sometimes the information systems department ends up selecting the RIS. As a radiology manager, you can help yourself and your department greatly by becoming more educated concerning the technology and terminology of radiology information systems. You can then participate in one of the most important decisions that will ever be made regarding your department. There is much confusion about the meanings of the terms interfaced and integrated. Two applications are generally considered integrated if they freely access and update each other's databases. Two applications are generally considered interfaced if they pass data to each other but don't directly access nor update the other's databases. Two more terms are centralized and decentralized. Centralized is the concept of "putting all of your eggs in one basket." Decentralization means you spread your resources out. The main difference between centralized and decentralized is that all components of a centralized system share the same fate (good or bad), while decentralized components operate independently and aren't affected directly by failures in another system. Another significant term relevant to RIS systems is HL7, which is a standardized data format that allows one application to pass data to another application in a format that the receiving application understands. RIS vendors generally fall in three categories: single-source vendors, multiproduct vendors and single-product vendors. Single-product vendors include best-of-breed vendors. No one approach is necessarily better than the others; which you choose will depend on your needs. When considering the purchase of an RIS system, there are important questions to ask yourself, the vendor and the vendors' customers as you gather information and prepare to make a decision.

Radiological assessment. A textbook on environmental dose analysis  

SciTech Connect

Radiological assessment is the quantitative process of estimating the consequences to humans resulting from the release of radionuclides to the biosphere. It is a multidisciplinary subject requiring the expertise of a number of individuals in order to predict source terms, describe environmental transport, calculate internal and external dose, and extrapolate dose to health effects. Up to this time there has been available no comprehensive book describing, on a uniform and comprehensive level, the techniques and models used in radiological assessment. Radiological Assessment is based on material presented at the 1980 Health Physics Society Summer School held in Seattle, Washington. The material has been expanded and edited to make it comprehensive in scope and useful as a text. Topics covered include (1) source terms for nuclear facilities and Medical and Industrial sites; (2) transport of radionuclides in the atmosphere; (3) transport of radionuclides in surface waters; (4) transport of radionuclides in groundwater; (5) terrestrial and aquatic food chain pathways; (6) reference man; a system for internal dose calculations; (7) internal dosimetry; (8) external dosimetry; (9) models for special-case radionuclides; (10) calculation of health effects in irradiated populations; (11) evaluation of uncertainties in environmental radiological assessment models; (12) regulatory standards for environmental releases of radionuclides; (13) development of computer codes for radiological assessment; and (14) assessment of accidental releases of radionuclides.

Accountable care organizations and radiology: threat or opportunity?  

PubMed

Although the anticipated rise of accountable care organizations brings certain potential threats to radiologists, including direct threats to revenue and indirect systemic changes jeopardizing the bargaining leverage of radiology groups, accountable care organizations, and other integrated health care delivery models may provide radiology with an important opportunity to reassert its leadership and assume a more central role within health care systems. Capitalizing on this potential opportunity, however, will require radiology groups to abandon the traditional "film reader" mentality and engage actively in the design and implementation of nontraditional systems service lines aimed at adding differentiated value to larger health care organizations. Important interlinked and mutually reinforcing components of systems service lines, derived from radiology's core competencies, may include utilization management and decision support, IT leadership, quality and safety assurance, and operational enhancements to meet organizational goals. Such systems-oriented service products, tailored to the needs of individual integrated care entities and supported by objective performance metrics, may provide market differentiation to shield radiology from commoditization and could become an important source of new nonclinical revenue.

For students and academics within the field of Medical Microbiology and Infectious Diseases, it is readily apparent what an enormous professional contribution Professor Hendrik Koornhof has made to this critically important specialty, not only in Africa, but worldwide. For those outside of the specialty, his contributions as a thoroughly decent person and role model are no less evident. What emerges in both spheres is his clear commitment to the welfare of others, as opposed to himself. His modesty and self-effacing nature have endeared Hendrik to many generations of students, peers and others who have indeed been privileged to have benefited from knowing him and working with him. In his 50 years with the South African Institute for Medical Research, and subsequently with the National Health Laboratory Service, Hendrik Koornhof has been the ideal academic, who is not as concerned about receiving financial rewards, recognition, etc. as about contributing to scientific knowledge. Many of his contributions have been in guiding others by his words and his deeds, and as a result he has been rewarded in seeing the accomplishments of his students, many of whom have gone on to achieve greatness in diverse fields, both locally and abroad. As we reflect in this festschrift on Hendrik's many achievements over 80 years, we thank him for more than just his research and teaching contributions over half a century with the South African Institute for Medical Research and the National Health Laboratory Service. We thank him for showing us what a privilege it is to work in the world of academia. Although we are not microbiologists, we thank him for having inspired us with the will to address problems of service delivery in the fight against microbiological diseases, which constitute the overwhelming bulk of the burden of disease in the developing world, both in Africa and further afield.

Small bowel radiology  

SciTech Connect

This book deals mainly with technique, experiences and results of the biphasic small bowel enema (enteroclysis) with barium and methyl cellulose. The method allows the evaluation of both morphology and function of the small bowel. The introduction describes the examination technique, basic patterns, interpretation and indications, while the atlas shows a broad spectrum of small bowel diseases (Crohn's disease, other inflammatory diseases, tumors, motility disorders, obstructions and malformations). The possibilities of small bowel radiology are demonstrated with reference to clinical findings and differential diagnoses.

Health Physics Instrumentation Museum Directory  

NSDL National Science Digital Library

This particular online collection from the Oak Ridge Associated Universities (a university consortium that oversees the Oak Ridge National Laboratory) contains over 1000 objects, many of which are on view at this site. The Health Physics Historical Instrumentation Museum Collection has been deemed the official repository for historical radiological instruments by the Health Physics Society, and at its essence, "chronicles the scientific and commercial history of radioactivity and radiation." This online collection is divided into sections that include atomic movie posters, radiation warning signs, radioluminescent items, ionization chambers, and electrometers. One of the more engaging sections details a number of items designed as radioactive quack cures, such as jars for adding radon to water, emanators for adding radon to water, and radium tablets and bath salts.

An evaluation of autoimmune antibody testing patterns in a Canadian health region and an evaluation of a laboratory algorithm aimed at reducing unnecessary testing.  

PubMed

Autoantibody tests are often ordered inappropriately. We aimed to evaluate the ordering patterns of these tests in our local health region and to develop a laboratory algorithm aimed at reducing unnecessary tests. Laboratory data including the number and sequence of tests, ordering physician specialties and results for antinuclear (ANA), extractable nuclear antigen (ENA) and anti-double stranded DNA (anti-dsDNA) antibody tests from 2007 to 2009 were evaluated. Based on this information and a clinical consensus meeting, an algorithm was developed and applied retrospectively to 1 year of inpatient laboratory data to simulate potential cost savings. We identified a large volume of these autoantibody tests performed, equating to testing costs of $862,706.72, where less than 17 % of each were positive. Repeated ANA tests were mostly ordered after a previously negative result, and 1 % of patients with negative results changed to ?1:160 on repeat testing. Close to half of all ENA and anti-dsDNA tests that were ordered were done so simultaneously with ANA, suggesting their use as screening tests. This was done more frequently in the inpatient setting. An algorithm was developed where ENA and anti-dsDNA tests would be cancelled if ANA was negative in the same sample. ANA repeated within 1 year would be cancelled and the prior result provided. Application of the algorithm retrospectively simulated a 30 % cost savings. Repeat testing and simultaneous ordering of multiple tests contributed to the excessive ordering of autoantibody tests in our health region. Our proposed algorithm would reduce testing costs and should be accompanied by appropriate educational information for physicians. PMID:23292519

Advances in pediatric interventional radiology.  

PubMed

The past year has seen important papers on the risk of acquired immunodeficiency syndrome in the invasive radiology laboratory with emphasis on awareness and prevention. Interventional catheterization techniques in congenital heart disease are reviewed. Valvoplasty of pulmonic stenosis has the greatest success and least complication rate. The majority of complications appear to be at the vascular access site and are more common in neonates and in procedures that are ultimately unsuccessful. Intrauterine valvoplasty of the aortic valve is reviewed as is angioplasty for a recurrent coarctation of the aorta. Closure of a persistent ductus arteriosus with a percutaneously introduced prosthesis and occlusion of congenital coronary artery arteriovenous fistulae with a variety of embolic agents is reviewed. The use of balloon-expandable stents in congenital heart disease is discussed. Traumatic rupture of the aorta, aortic and great vessel involvement in Takayasu's disease, and mucopolysaccharidosis are reviewed along with imaging of congenital anomalies of the aortic arch. The diagnosis of vascular complications of renal transplants is summarized. PMID:1385721

Public participation in radiological surveillance.  

PubMed

In 1989, Pacific Northwest National Laboratory developed a program, for the U.S. Department of Energy, to involve local citizens in environmental surveillance at the Hanford Site. The Community-Operated Environmental Surveillance Program was patterned after similar community-involvement efforts at the Nevada Test Site and the Three Mile Island nuclear facility. Its purpose is to increase the flow of information to the public, thereby enhancing the public's awareness and understanding of surveillance activities. The program consists of two components: radiological air monitoring at nine offsite locations and agricultural product sampling at selected locations near the site. At each air-monitoring station, two local school teachers collect air particulate samples and operate equipment to monitor ambient radiation levels. Atmospheric tritium samples (as water vapor) are also collected at some locations. Four of the air-monitoring stations include large, colorful informational displays for public viewing. These displays provide details on station equipment, sample types, and sampling purposes. Instruments in the displays also monitor, record, and show real-time ambient radiation readings (measured with a pressurized ionization chamber) and meteorological conditions. Agricultural products, grown primarily by middle-school-aged students, are obtained from areas downwind of the site. Following analysis of these samples, environmental surveillance staff visit the schools to discuss the results with the students and their teachers. The data collected by these air and agricultural sampling efforts are summarized with other routinely collected sitewide surveillance data and reported annually in the Hanford Site environmental report.

Public health assessment for Jet Propulsion Laboratory (NASA), Pasadena, Los Angeles County, California, Region 9: CERCLIS number CA9800013030. Final report  

SciTech Connect

The National Aeronautics and Space Administration (NASA) Jet Propulsion Laboratory (JPL) is located in Pasadena, California, northeast of Interstate 210. As a result of former site activities, chemicals, primarily volatile organic compounds (VOC) and perchlorate (a component of solid rocket fuel), used at JPL have been released to soil and groundwater. The Agency for Toxic Substances and Disease Registry (ATSDR) conducted site visits in 1997 to assess the potential for public health hazards. During these visits, ATSDR identified two pathways where people could potentially be exposed to site-related contaminants: (1) exposure to contaminated groundwater and (2) exposure to contaminated soil. ATSDR also identified the following primary community concerns: (1) future groundwater and drinking water quality and (2) increased incidence of Hodgkin`s disease. ATSDR determined that VOC-contaminated groundwater does not present a past, present, or future public health to JPL employees or nearby residents. ATSDR also determined that exposure, if any, to contaminated soils associated with the JPL site and in the Arroyo Secco near the JPL boundary is unlikely to cause either short-term or long-term adverse health effects to employees and the public.

HIV-associated Prospective Memory Impairment in the Laboratory Predicts Failures on a Semi-naturalistic Measure of Health Care Compliance  

PubMed Central

HIV-associated neurocognitive impairment, particularly in the domain of prospective memory (ProM), increases the risk of poor everyday functioning outcomes, including medication non-adherence. However, whether ProM plays a role in health care compliance outside of the realm of medication adherence remains to be determined. This study evaluated the hypothesis that ProM is an independent predictor of failure to comply with non-medication related instructions akin to those commonly given by health care providers. Participants were 139 HIV-infected adults who underwent medical, psychiatric, and neuropsychological assessments, including a laboratory-based measure of ProM. To assess real-world compliance, participants were instructed to call the examiner 24 hours after the evaluation and report how many hours they had slept. Individuals who failed to correctly comply with these instructions (n=104) demonstrated significantly lower performance on both time- and event-based ProM at baseline than the compliant group (n=35), an effect that was primarily driven by errors of omission. ProM remained a significant predictor of noncompliance after controlling for potential confounders, including demographics (e.g., education), traditional cognitive measures of retrospective memory and executive functions, and psychiatric factors (e.g., depression). Results support the hypothesis that ProM plays a unique role in compliance with health care instructions for HIV disease management and may inform interventions designed to improve treatment outcomes.

Results of the outdoor radiological survey at the Portsmouth Gaseous Diffusion Plant site, Piketon, Ohio  

SciTech Connect

The Portsmouth Gaseous Diffusion Plant (PORTS) is owned by the US Department of Energy (DOE) and managed by Martin Marietta Energy Systems, Inc. As shown in Fig. 1, the plant is located in sparsely populated, rural Pike County, Ohio. PORTS began in 1952 as part of the Atomic Energy Commission`s (AEC) proposed expansion of the gaseous diffusion program in order to increase the production of enriched uranium. The 3,708-acre site is about a half mile east of US Interstate 23 (Fig. 2) and approximately 1 mile east of the Scioto River Valley (Fig. 3). The current layout of the plant is shown on Fig. 4. The principal site process is the separation of uranium isotopes {sup 235}U and {sup 238}U through gaseous diffusion. This uranium enrichment process involves the more rapid diffusion of lighter molecules of UF{sub 6} (uranium hexaflouride) through the barrier walls of a porous tube. The end result is a UF{sub 6} stream that is slightly enriched in the {sup 235}U isotope. The separation process is repeated in a cascade arrangement until the desired concentration is reached. At the request of the PORTS Environmental Safety and Health Division, the Health and Safety Research Division (HASRD), Oak Ridge National Laboratory (ORNL), conducted a radiological survey of the outdoor surface environment of the PORTS site. The surveyed area covered approximately 150 acres of fenced ground consisting of dirt, asphalt, and concrete. The survey was performed between July 1990 and April 1991, and the results reported to PORTS, Health Physics Department. The survey purpose was to determine the extent of radiological contamination and to locate and prioritize areas of concern from both a worker health/safety and an environmental standpoint. Specifically, the objectives of the survey were to assess the areal radioactive status of the site and to analyze surface soil samples for the presence of selected radionuclides. The principal radionuclide of concern is uranium.

Federal Radiological Monitoring and Assessment Center Analytical Response  

SciTech Connect

The Federal Radiological Monitoring and Assessment Center (FRMAC) is authorized by the Federal Radiological Emergency Response Plan to coordinate all off-site radiological response assistance to state and local government s, in the event of a major radiological emergency in the United States. The FRMAC is established by the U.S. Department of Energy, National Nuclear Security Administration, to coordinate all Federal assets involved in conducting a comprehensive program of radiological environmental monitoring, sampling, radioanalysis, quality assurance, and dose assessment. During an emergency response, the initial analytical data is provided by portable field instrumentation. As incident responders scale up their response based on the seriousness of the incident, local analytical assets and mobile laboratories add additional capability and capacity. During the intermediate phase of the response, data quality objectives and measurement quality objectives are more rigorous. These higher objectives will require the use of larger laboratories, with greater capacity and enhanced capabilities. These labs may be geographically distant from the incident, which will increase sample management challenges. This paper addresses emergency radioanalytical capability and capacity and its utilization during FRMAC operations.

Environmental health-risk assessment for tritium releases at the National Tritium Labeling Facility at Lawrence Berkeley National Laboratory  

SciTech Connect

This risk assessment calculates the probability of experiencing health effects, including cancer incidence due to tritium exposure for three groups of people: (1) LBNL workers near the LBNL facility--Building 75--that uses tritium; (2) other workers at LBNL and nearby neighbors; and (3) people who use the UC Berkeley campus area, and some Berkeley residents. All of these groups share the same probability of health effects from the background radiation from natural sources in the Berkeley area environment, including an increased risk of developing a cancer of 11,000 chances per million. In calculating risk the authors assumed continuous operation in Building 75 for at least a human lifetime. Under this assumption, LBNL workers located near Building 75 have an additional risk of 60 chances out of one million to suffer a cancer; other workers at LBNL and people who live near LBNL have an additional risk of six chances out of one million over a lifetime of exposure; and users of the UC Berkeley campus area and other residents of Berkeley have an additional risk of less than once chance out of one million over a lifetime.

A Checklist to Improve Patient Safety in Interventional Radiology  

SciTech Connect

To develop a specific RADiological Patient Safety System (RADPASS) checklist for interventional radiology and to assess the effect of this checklist on health care processes of radiological interventions. On the basis of available literature and expert opinion, a prototype checklist was developed. The checklist was adapted on the basis of observation of daily practice in a tertiary referral centre and evaluation by users. To assess the effect of RADPASS, in a series of radiological interventions, all deviations from optimal care were registered before and after implementation of the checklist. In addition, the checklist and its use were evaluated by interviewing all users. The RADPASS checklist has two parts: A (Planning and Preparation) and B (Procedure). The latter part comprises checks just before starting a procedure (B1) and checks concerning the postprocedural care immediately after completion of the procedure (B2). Two cohorts of, respectively, 94 and 101 radiological interventions were observed; the mean percentage of deviations of the optimal process per intervention decreased from 24 % before implementation to 5 % after implementation (p < 0.001). Postponements and cancellations of interventions decreased from 10 % before implementation to 0 % after implementation. Most users agreed that the checklist was user-friendly and increased patient safety awareness and efficiency. The first validated patient safety checklist for interventional radiology was developed. The use of the RADPASS checklist reduced deviations from the optimal process by three quarters and was associated with less procedure postponements.

CKD surveillance using laboratory data from the population-based National Health and Nutrition Examination Survey (NHANES).  

PubMed

Surveillance for chronic kidney disease (CKD) using nationally representative samples of the US population is central in providing information about the magnitude and trends in CKD burden that will guide disease management and prevention planning for clinicians and public health authorities. We used a cross-sectional study design to estimate the change in prevalence of CKD over time by using National Health and Nutrition Examination Survey (NHANES) data. NHANES III (1988-1994) included 15,488 participants and NHANES rounds 1999-2004 included 13,233 participants older than 20 years with serum creatinine measurements who were examined in a mobile examination center. Early stages of CKD were defined by glomerular filtration rate (GFR) estimated by using the Modification of Diet in Renal Disease (MDRD) Study equation and urinary albumin-creatinine ratio following the classification system established by the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative. Moderately decreased GFR increased in prevalence from 5.4% to 7.7% (P < 0.001) and severely decreased GFR increased from 0.21% to 0.35% (P = 0.02) from 1988-1994 to 1999-2004. Within CKD stage 3, 18.6% +/- 1.6% (SE) of individuals should be referred to a nephrologist following a proposed set of criteria for referral; referral rates were highest for individuals with diabetes and lower in whites compared with other race-ethnicity groups. These survey data suggest that the prevalence of CKD has increased between 1988-1994 and 1999-2004. Surveillance for early stages of CKD (stages 1 to 4) should monitor these and other trends.

NLP-based Identification of Pneumonia Cases from Free-Text Radiological Reports  

PubMed Central

Radiological reports are a rich source of clinical data which can be mined to assist with biosurveillance of emerging infectious diseases. In addition to biosurveillance, radiological reports are an important source of clinical data for health service research. Pneumonias and other radiological findings on chest xray or chest computed tomography (CT) are one type of relevant finding to both biosurveillance and health services research. In this study we examined the ability of a Natural Language Processing system to accurately identify pneumonias and other lesions from within free-text radiological reports. The system encoded the reports in the SNOMED CT Ontology and then a set of SNOMED CT based rules were created in our Health Archetype Language aimed at the identification of these radiological findings and diagnoses. The encoded rule was executed against the SNOMED CT encodings of the radiological reports. The accuracy of the reports was compared with a Clinician review of the Radiological Reports. The accuracy of the system in the identification of pneumonias was high with a Sensitivity (recall) of 100%, a specificity of 98%, and a positive predictive value (precision) of 97%. We conclude that SNOMED CT based computable rules are accurate enough for the automated biosurveillance of pneumonias from radiological reports.

Use of a CO{sub 2} pellet non-destructive cleaning system to decontaminate radiological waste and equipment in shielded hot cells at the Bettis Atomic Power Laboratory  

SciTech Connect

This paper details how the Bettis Atomic Power Laboratory modified and utilized a commercially available, solid carbon dioxide (CO{sub 2}) pellet, non-destructive cleaning system to support the disposition and disposal of radioactive waste from shielded hot cells. Some waste materials and equipment accumulated in the shielded hot cells cannot be disposed directly because they are contaminated with transuranic materials (elements with atomic numbers greater than that of uranium) above waste disposal site regulatory limits. A commercially available CO{sub 2} pellet non-destructive cleaning system was extensively modified for remote operation inside a shielded hot cell to remove the transuranic contaminants from the waste and equipment without generating any secondary waste in the process. The removed transuranic contaminants are simultaneously captured, consolidated, and retained for later disposal at a transuranic waste facility.

Abdominal hernias: Radiological features  

PubMed Central

Abdominal wall hernias are common diseases of the abdomen with a global incidence approximately 4%-5%. They are distinguished in external, diaphragmatic and internal hernias on the basis of their localisation. Groin hernias are the most common with a prevalence of 75%, followed by femoral (15%) and umbilical (8%). There is a higher prevalence in males (M:F, 8:1). Diagnosis is usually made on physical examination. However, clinical diagnosis may be difficult, especially in patients with obesity, pain or abdominal wall scarring. In these cases, abdominal imaging may be the first clue to the correct diagnosis and to confirm suspected complications. Different imaging modalities are used: conventional radiographs or barium studies, ultrasonography and Computed Tomography. Imaging modalities can aid in the differential diagnosis of palpable abdominal wall masses and can help to define hernial contents such as fatty tissue, bowel, other organs or fluid. This work focuses on the main radiological findings of abdominal herniations.

Resident moonlighting in radiology.  

PubMed

The indebtedness of medical school graduates has increased dramatically, and this indebtedness, combined with a shortage of radiologists, may result in more moonlighting by radiology residents. Residents may choose to moonlight for an institution not affiliated with the residency program (external moonlighting) or within the same institution as the residency program (internal moonlighting). If residents choose to engage in external moonlighting, they must have a full medical license and separate malpractice insurance and should be aware of their liability. Internal moonlighting is permissible under a resident's limited license and the malpractice coverage provided by the residency but must be within the duty hour requirements of the residency program. Residents with J-1 visas may engage only in internal moonlighting duties that are specifically part of the training program. Internal moonlighting under the control of the residency program offers the most opportunity to supervise residents to make sure that the patient care they are providing is commensurate with their level of experience.

Standardized radiological dose evaluations  

SciTech Connect

Following the end of the Cold War, the mission of Rocky Flats Environmental Technology Site changed from production of nuclear weapons to cleanup. Authorization baseis documents for the facilities, primarily the Final Safety Analysis Reports, are being replaced with new ones in which accident scenarios are sorted into coarse bins of consequence and frequency, similar to the approach of DOE-STD-3011-94. Because this binning does not require high precision, a standardized approach for radiological dose evaluations is taken for all the facilities at the site. This is done through a standard calculation ``template`` for use by all safety analysts preparing the new documents. This report describes this template and its use.

Laboratory evaluation of a prototype photochemical chamber designed to investigate the health effects of fresh and aged vehicular exhaust emissions  

PubMed Central

Laboratory experiments simulating atmospheric aging of motor vehicle exhaust emissions were conducted using a single vehicle and a photochemical chamber. A compact automobile was used as a source of emissions. The vehicle exhaust was diluted with ambient air to achieve carbon monoxide (CO) concentrations similar to those observed in an urban highway tunnel. With the car engine idling, it is expected that the CO concentration is a reasonable surrogate for volatile organic compounds (VOCs) emissions. Varying the amount of dilution of the exhaust gas to produce different CO concentrations, allowed adjustment of the concentrations of VOCs in the chamber to optimize production of secondary organic aerosol (SOA) needed for animal toxicological exposures. Photochemical reactions in the chamber resulted in nitric oxide (NO) depletion, nitrogen dioxide (NO2) formation, ozone (O3) accumulation, and SOA formation. A stable SOA concentration of approximately 40 µg m?3 at a chamber mean residence time of 30 min was achieved. This relatively short mean residence time provided adequate chamber flow output for both particle characterization and animal exposures. The chamber was operated as a continuous flow reactor for animal toxicological tests. SOA mass generated from the car exhaust diluted with ambient air was almost entirely in the ultrafine mode. Chamber performance was improved by using different types of seed aerosol to provide a surface for condensation of semivolatile reaction products, thus increasing the yield of SOA. Toxicological studies using Sprague-Dawley rats found significant increases of in vivo chemiluminescence in lungs following exposure to SOA.

The Northern Marshall Islands radiological survey: A quality control program for radiochemical and gamma spectroscopy analysis  

SciTech Connect

From 1979 to 1989, approximately 25,000 Post Northern Marshall Islands Radiological Survey (PNMIRS) samples were collected, and over 71,400 radiochemical and gamma spectroscopy analyses were performed to establish the concentration of {sup 90}Sr, {sup 137}Cs, {sup 241}Am, and plutonium isotopes in soil, vegetation, fish, and animals in the Northern Marshall Islands. While the Low Level Gamma Counting Facility (B379) in the Health and Ecological Assessment (HEA) division accounted for over 80% of all gamma spectroscopy analyses, approximately 4889 radiochemical and 5437 gamma spectroscopy analyses were performed on 4784 samples of soil, vegetation, terrestrial animal, and marine organisms by outside laboratories. Four laboratories were used by Lawrence Livermore National Laboratory (LLNL) to perform the radiochemical analyses: Thermo Analytical Norcal, Richmond, California (TMA); Nuclear Energy Services, North Carolina State University (NCSU); Laboratory of Radiation Ecology, University of Washington (LRE); and Health and Ecological Assessment (HEA) division, LLNL, Livermore, California. Additionally, LRE and NCSU were used to perform gamma spectroscopy analyses. The analytical precision and accuracy were monitored by including blind duplicates and natural matrix standards in each group of samples analyzed. On the basis of reported analytical values for duplicates and standards, 88% of the gamma and 87% of the radiochemical analyses in this survey were accepted. By laboratory, 93% of the radiochemical analyses by TMA; 88% of the gamma-ray spectrometry and 100% of the radiochemistry analyses by NCSU; 89% of the gamma spectroscopy and 87% of the radiochemistry analyses by LRE; and 90% of the radiochemistry analyses performed by HEA`s radiochemistry department were accepted.

Risk assessment and optimization (ALARA) analysis for the environmental remediation of Brookhaven National Laboratory`s hazardous waste management facility  

SciTech Connect

The Department of Energy`s (DOE) Office of Environment, Safety, and Health (EH) sought examples of risk-based approaches to environmental restoration to include in their guidance for DOE nuclear facilities. Extensive measurements of radiological contamination in soil and ground water have been made at Brookhaven National Laboratory`s Hazardous Waste Management Facility (HWMF) as part of a Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) remediation process. This provided an ideal opportunity for a case study. This report provides a risk assessment and an {open_quotes}As Low as Reasonably Achievable{close_quotes} (ALARA) analysis for use at other DOE nuclear facilities as an example of a risk-based decision technique. This document contains the Appendices for the report.

Outbreak of Transient Conversions of the QuantiFERON-TB Gold In-Tube Test in Laboratory Health Care Worker Screenings  

PubMed Central

Gamma interferon release assays were recently introduced in health care worker (HCWs) screenings for tuberculosis surveillance. In longitudinal surveys, conversions and reversions are seen, and yet whether these changes are unspecific or are an expression of new infections and microbial clearance remains unclear. In order to further elucidate these changes, we analyzed an outbreak of 15 transient conversions in 53 HCWs who operate in the same laboratory and handle specimens potentially containing Mycobacterium tuberculosis who underwent screening by the QuantiFERON-TB Gold In-Tube (QFT-GIT) test between 11 May and 30 June 2010: 15/46 (33%) negative HCWs showed a conversion and then reverted after 7 to 107 days. To validate these results, an evaluation of methodological procedures and test reliability, as well as an analysis of results obtained during the same period and processed by the same laboratory, was carried out. For the latter purpose, QFT-GIT results determined for 78 ward HCWs who underwent screening during the same period and were employed in departments with at least 3 infectious tuberculosis patients per year or had cared for an infectious patient without airborne precautions were analyzed with the following results: 6/63 (9%) HCWs with negative results in 3 different departments showed transient conversion (P = 0.002; odds ratio, 4.60; 95% confidence interval, 1.62 to 13.04). A retrospective survey of in-house biosafety practices led to determination of a single exposure factor within the laboratory. These data emphasize the validity of the hypothesis that a transient conversion demonstrates the presence of a real tubercular infection and could be an important indicator for occupational biosafety concerns. They also confirm that subjects with recent conversion should be retested before chest radiography and chemotherapy is offered.

Regulating the unknown: Managing the occupational health risks of nanomedical technologies and nanopharmaceuticals in the research laboratory  

NASA Astrophysics Data System (ADS)

Novel technologies and their resultant products demand fresh ways of thinking about pre-market risk analysis and post-market surveillance. A regulatory framework that is responsive to emerging knowledge about the hazards of novel technologies offers repeatable and transparent processes and remains economically and socially feasible. Workers are an especially vulnerable population who are exposed to unknown hazards of novel technologies and serve often as unwitting sentinels of impending risks. This Grounded Theory-based case study identifies gaps in our current ability to regulate novel technologies so as to minimize occupational health risks and offers necessary modifications for an environment that is conducive to proper regulation. Nanopharmaceuticals and the nano-based technologies at their base are used by way of exemplar technologies that are currently taxing the ability of the regulatory system to provide adequate oversight. Ambiguities of definition, absence of a tracking system (of who is doing nanotechnology research), and the paucity of scientific evidence to support risk management efforts are among the findings of the study and need to be addressed as ameliorative steps toward an effective regulatory structure.

RADRELAY RADIOLOGICAL DATA LINK DEVICE  

SciTech Connect

The RadRelay effort developed small, field appropriate, portable prototype devices that allow radiological spectra to be downloaded from field radiological detectors, like the identiFINDER-U, and transmitted to land based experts. This communications capability was designed for the U. S. Coast Guard (USCG) but is also applicable to the Customs and Border Protection (CBP) personnel working in remote locations. USCG Level II personnel currently use the identiFINDER-U Hand-Held Radioisotope ID Devices (HHRIID) to detect radiological materials during specific boarding operations. These devices will detect not only radiological emissions but will also evaluate those emissions against a table of known radiological spectra. The RadRelay has been developed to significantly improve the functionality of HHRIID, by providing the capability to download radiological spectra and then transmit them using satellite or cell phone technology. This remote wireless data transfer reduces the current lengthy delay often encountered between the shipboard detection of unknown radiological material and the evaluation of that data by technical and command personnel. That delay is reduced from hours to minutes and allows the field located personnel to remain on station during the inspection and evaluation process.

[Radiological diagnostics of bronchioloalveolar carcinoma].  

PubMed

Bronchioloalveolar carcinoma is an exceptional morphological case of adenocarcinoma, compiling 3-9% of primary lung cancer. Its growth is characterized by spread of neoplastic cells in the peripheral air space without destroying underlying architecture. Carcinoma is spreading by blood vessels and alveoles. Bronchioloalveolar carcinoma distinguishes itself by variety of clinical and radiological symptoms. During the radiological researches separates consolidating infiltration and solitary types. They manifest by unequal density which can be in 30% incorrectly valuing as bronchopneumonia. The aim of our work is to analyze confirmed cases of bronchioloalveolar carcinoma and to summarize definite characteristic radiological signs, which can help to diagnose bronchioloalveolar carcinoma.

Anti-malarial prescription practices among outpatients with laboratory-confirmed malaria in the setting of a health facility-based sentinel site surveillance system in Uganda  

PubMed Central

Background Most African countries have adopted artemisinin-based combination therapy (ACT) as the first-line treatment for uncomplicated malaria. The World Health Organization now recommends limiting anti-malarial treatment to those with a positive malaria test result. Limited data exist on how these policies have affected ACT prescription practices. Methods Data were collected from all outpatients presenting to six public health facilities in Uganda as part of a sentinel site malaria surveillance programme. Training in case management, encouragement of laboratory-based diagnosis of malaria, and regular feedback were provided. Data for this report include patients with laboratory confirmed malaria who were prescribed anti-malarial therapy over a two-year period. Patient visits were analysed in two groups: those considered ACT candidates (defined as uncomplicated malaria with no referral for admission in patients???4 months of age and???5 kg in weight) and those who may not have been ACT candidates. Associations between variables of interest and failure to prescribe ACT to patients who were ACT candidates were estimated using multivariable logistic regression. Results A total of 51,355 patient visits were included in the analysis and 46,265 (90.1%) were classified as ACT candidates. In the ACT candidate group, 94.5% were correctly prescribed ACT. Artemether-lumefantrine made up 97.3% of ACT prescribed. There were significant differences across the sites in the proportion of patients for whom there was a failure to prescribe ACT, ranging from 3.0-9.3%. Young children and woman of childbearing age had higher odds of failure to receive an ACT prescription. Among patients who may not have been ACT candidates, the proportion prescribed quinine versus ACT differed based on if the patient had severe malaria or was referred for admission (93.4% vs 6.5%) or was below age or weight cutoffs for ACT (41.4% vs 57.2%). Conclusions High rates of compliance with recommended ACT use can be achieved in resource-limited settings. The unique health facility-based malaria surveillance system operating at these clinical sites may provide a framework for improving appropriate ACT use at other sites in sub-Saharan Africa.

An assessment of the external radiological impact in areas of Greece with elevated natural radioactivity.  

PubMed

In the present study, the radiological impact assessment in three selected areas of elevated natural radioactivity in Greece is attempted, based on measurements, theoretical relations, and simple model application. These areas are Milos--an island of volcanic origin in Cyclades Archipelago, Ikaria--an island in the Eastern Aegean Sea and Loutraki--a coastal area in mainland Greece. These areas are characterized by their geothermal springs and vents, which emit fluids into the littoral and sublittoral zones. The results include: (a) the exposure dose rates assessed by a car-borne scintillation spectrometry system; (b) laboratory measurements of the activity concentrations of the gamma-emitters of 238U and 232Th series and 40K in soil, spring water, seawater and sediments by gamma-spectrometry; (c) estimations of the effective dose rate equivalents and health risk assessment for humans and external dose rates for natural aquatic populations in relation to organism habitat; and (d) a radiological evaluation for the environmental quality, in terms of the discrete zones of impact of ionizing radiation.

Quarterly environmental radiological survey summary  

SciTech Connect

Routine radiological surveys are part of the near-facility environmental monitoring program which monitors and helps direct the reduction of the radiological areas at the Hanford Site. The routine radiological surveys are performed by the Southern Area Remediation Support Group and the Site Support Services Radiological Control Group as directed by Near- Field Monitoring. The surveys included in this program consist of inactive waste sites; outdoor radiological control areas; tank farm perimeters and associated diversion boxes, lift stations, and vent stations; perimeters of active or uncovered waste Bites such as burial grounds, retention basins, ponds, process trenches, and ditches; underground pipelines; and road and rail surfaces (Figures 1 through 10). This report provides a Bummary of the radiological surveys performed during the Third Quarter of 1996. The status of corrective actions required from current and past reports are also discussed. A waste site survey schedule, WHC-SP-0098-7, was developed by Near-Field Monitoring and reviewed by the Southern Area Remediation Support Group and the Site Support Services Radiological Control Group. Near-Field Monitoring reviews the radiological survey reports and files a copy for historical purposes and reference. Radiological conditions are tracked and trends noted. All sites are surveyed at least once each year. The survey frequencies for particular sites are based on site history, radiological conditions, and general maintenance. special surveys may be conducted at irregular frequencies if conditions warrant (e.g., growth of deep-rooted vegetation is noted at a waste site). Radiological surveys are conducted to detect surface contamination and document changes in vegetation growth, biological intrusion, erosion, and general site maintenance conditions. Survey data are compared with standards identified in WHC-CM-7-5, Environmental Comipliance, as well as previous surveys `to recognize possible trends, assess environmental impacts, and help determine where corrective actions are needed. Landlords of the sites found out of compliance may be issued a Radiological Problem Report (RPR) from the appropriate radiological Control Groups. Should the landlord, of a WHC-managed facility, fail to respond to the identified problem in a timely manner, or if the corrective action will require a long-term commitment, Near-Field Monitoring will issue a Compliance Assessment Report (CAR). The Compliance Assessment Report, formerly called Surveillance Compliance Inspection Report (SCIR), is tracked to completion by Near-Field Monitoring. Open SCIRs and CARs are listed in Table I of this report. The surveys scheduled for this program consist of inactive waste sites; outdoor radiological areas; tank farm perimeters and associated diversion boxes, lift Btations, and vent stations; perimeters of active or uncovered waste sites such as burial grounds, retention basins, ponds, process trenches, and ditches; underground pipelines; and road and rail surfaces.. Surveillance of the active nuclear facilities an0484d inside the tank farras is the responsibility of the facility. These radiological surveys are to determine surface radiological conditions and do not constitute a release survey. Therefore, surveys that detect no contamination in radiological areas do not release the site from control but may result in a posting status change.

Introduction to radiological performance assessment  

SciTech Connect

A radiological performance assessment is conducted to provide reasonable assurance that performance objectives for low-level radioactive waste (LLW) disposal will be met. Beginning in the early stages of development, a radiological performance assessment continues through the operational phase, and is instrumental in the postclosure of the facility. Fundamental differences exist in the regulation of commercial and defense LLW, but the radiological performance assessment process is essentially the same for both. The purpose of this document is to describe that process in a concise and straightforward manner. This document focuses on radiological performance assessment as it pertains to commercial LLW disposal, but is applicable to US Department of Energy sites as well. Included are discussions on performance objectives, site characterization, and how a performance assessment is conducted. A case study is used to illustrate how the process works as a whole. A bibliography is provided to assist in locating additional information.

Computer applications in radiology.  

PubMed

Computer applications in radiology are evolving rapidly, tied to incremental improvements in hardware, software, and methods. In computer hardware, the emergence of dramatically improved graphic and computational performance for engineering workstations enables their use for visualization. Major changes in networking, storage, and display technology play a major role in influencing applications. The use of three-dimensional digitizers to perform localization of real three-dimensional points in conjunction with images and the rendering of objects using rapid prototyping methods, such as stereolithography, were recently reported. Major software advances have taken place through the availability of applications packages that are operated with menu-driven or point-and-click user interfaces, data flow languages, or complete turnkey applications. Imaging methods including CT, MR imaging, digital radiography, biomagnetism, and optical range sensing, which take advantage of advanced computer technology, are new this year. Image processing for multimodality fusion or image registration, visualization, reconstruction, and quantification of images, have been reported at a wide variety of conferences and in key publications. New computer methods to fabricate custom orthopaedic implants, and to improve imaging technology assessment were introduced. PMID:2049275

Medical-legal issues in radiology: prevention and control.  

PubMed

Concerns about legal implications affect many decisions of the average radiologist, and physicians do not always appreciate the validity of these concerns. However, such concerns often influence radiologists' decisions more than is warranted. An improved understanding of the law and its ramifications may serve to prevent adverse legal effects found in the everyday practice of radiology. Legal issues influence radiology in many ways. Two important ways the law affects the practice of radiology relate to the business affairs of radiologists and to the radiologist's duty to perform to a standard of care. Legal issues relate to the business aspects of radiology through radiologists' relationship to their group practice and the radiology group's relation to the outside world. Radiology groups use legal services for issues such as employment contracts, hospital privileges, group relations, and bylaws. They make decisions with major legal implications when they establish their standard business practices. These decisions range from business procedures that ensure a timely delivery of service to the choice and implementation of quality assurance systems to how to ensure that patients are informed of the results of a radiologic examination. Legal matters affect many business decisions radiology groups make. Antitrust law is concerned about issues such as cost sharing, price sharing, mergers, acquisitions, and practice patterns. Laws limit the right to practice radiology. Billing practices, conflicts of interest, self-referral, right to refuse care, employment practices--all have substantial legal implications. These issues are a concern of every practicing radiologist. Changes in our health care system may cause new legal obligations. An appreciation of the relationship radiologists must have with payors and patients is increasingly important in preventing medical-legal problems. These additional duties and responsibilities occur when many physicians and the public at large seem to feel they are already overburdened with legal duties and responsibilities. A lack of familiarity with the legitimate relationship of the law to everyday life may greatly affect radiologists' job satisfaction. Many acts physicians perform in the practice of radiology have legal implications not often recognized by the practicing radiologist. This monograph seeks to enhance radiologists' understanding of some common and important legal issues related to their practice of medicine. We hope that this monograph will help radiologists appreciate the legal implications of their behavior. The opinions expressed in this monograph are those of the authors and should not be inferred to represent the official views of any government agency.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:7664570

Biological Treatment of Petroleum in Radiologically Contaminated Soil  

SciTech Connect

This chapter describes ex situ bioremediation of the petroleum portion of radiologically co-contaminated soils using microorganisms isolated from a waste site and innovative bioreactor technology. Microorganisms first isolated and screened in the laboratory for bioremediation of petroleum were eventually used to treat soils in a bioreactor. The bioreactor treated soils contaminated with over 20,000 mg/kg total petroleum hydrocarbon and reduced the levels to less than 100 mg/kg in 22 months. After treatment, the soils were permanently disposed as low-level radiological waste. The petroleum and radiologically contaminated soil (PRCS) bioreactor operated using bioventing to control the supply of oxygen (air) to the soil being treated. The system treated 3.67 tons of PCRS amended with weathered compost, ammonium nitrate, fertilizer, and water. In addition, a consortium of microbes (patent pending) isolated at the Savannah River National Laboratory from a petroleum-contaminated site was added to the PRCS system. During operation, degradation of petroleum waste was accounted for through monitoring of carbon dioxide levels in the system effluent. The project demonstrated that co-contaminated soils could be successfully treated through bioventing and bioaugmentation to remove petroleum contamination to levels below 100 mg/kg while protecting workers and the environment from radiological contamination.

2000 RSNA annual oration in diagnostic radiology: The future of interventional radiology.  

PubMed

Origins in imaging, procedural emphasis, and dependence on innovation characterize interventional radiology, which will continue as the field of image-guided minimally invasive therapies. A steady supply of innovators will be needed. Current workforce shortages demand that this problem be addressed and in an ongoing fashion. Interventional radiology's major identity problem will require multiple corrective measures, including a name change. Diagnostic radiologists must fully embrace the concept of the dedicated interventionalist. Interspecialty turf battles will continue, especially with cardiologists and vascular surgeons. To advance the discipline, interventional radiologists must remain involved in cutting-edge therapies such as endograft repair of aortic aneurysms and carotid stent placement. As the population ages, interventionalists will experience a shift toward a greater emphasis on cancer treatment. Political agendas and public pressure will improve access to care and result in managed health care reforms. Academic centers will continue to witness a decline in time and resources available to pursue academic missions. The public outcry for accountability will result in systems changes aimed at reducing errors and process changes in the way physicians are trained, certified, and monitored. Evidence-based medicine will be the watchword of this century. Interventional radiology will maintain its role through development of methods for delivery of genes, gene products, and drugs to specific target sites; control of angiogenesis and other biologic processes; and noninvasive image-guided delivery of various forms of energy for ablation.

Nuclear and Radiological Forensics and Attribution Overview  

SciTech Connect

The goal of the U.S. Department of Homeland Security (DHS) Nuclear and Radiological Forensics and Attribution Program is to develop the technical capability for the nation to rapidly, accurately, and credibly attribute the origins and pathways of interdicted or collected materials, intact nuclear devices, and radiological dispersal devices. A robust attribution capability contributes to threat assessment, prevention, and deterrence of nuclear terrorism; it also supports the Federal Bureau of Investigation (FBI) in its investigative mission to prevent and respond to nuclear terrorism. Development of the capability involves two major elements: (1) the ability to collect evidence and make forensic measurements, and (2) the ability to interpret the forensic data. The Program leverages the existing capability throughout the U.S. Department of Energy (DOE) national laboratory complex in a way that meets the requirements of the FBI and other government users. At the same time the capability is being developed, the Program also conducts investigations for a variety of sponsors using the current capability. The combination of operations and R&D in one program helps to ensure a strong linkage between the needs of the user community and the scientific development.

Human performance in radiological survey scanning  

SciTech Connect

The probability of detecting residual contamination in the field using portable radiological survey instruments depends not only on the sensitivity of the instrumentation used in scanning, but also on the surveyor`s performance. This report provides a basis for taking human performance into account in determining the minimum level of activity detectable by scanning. A theoretical framework was developed (based on signal detection theory) which allows influences on surveyors to be anticipated and understood, and supports a quantitative assessment of performance. The performance of surveyors under controlled yet realistic field conditions was examined to gain insight into the task and to develop means of quantifying performance. Then, their performance was assessed under laboratory conditions to quantify more precisely their ability to make the required discriminations. The information was used to characterize surveyors` performance in the scanning task and to provide a basis for predicting levels of radioactivity that are likely to be detectable under various conditions by surveyors using portable survey instruments.

The Radiological Manifestations of the Aberrant Air Surrounding the Pleura: In the Embryological View  

PubMed Central

The radiological manifestations of the aberrant air surrounding the pleura are varied because of the air outlining the organs in and out of the visceral space. The continuity of the visceral space from the neck, mediastinum to the retroperitoneum is originated from embryological development, which is compatible with the findings through laboratory experiments, cadaveric anatomy, and thoracic computer tomography image. We reviewed the embryo development to understand the anatomy of body cavity, which can determine the radiological findings of pneumomediastinum and pneumothorax.

Social radiology: Where to now?  

PubMed Central

Radiology is a relatively high-cost and high-maintenance aspect of medicine. Expertise is constantly required, from acquisition to its use and quality assurance programmes. However, it is an integral part of healthcare practice, from disease diagnosis, surveillance and prevention to treatment monitoring. It is alarming that two thirds of the world is deficient in or lacks even basic diagnostic imaging. Developing and underdeveloped countries need help in improving medical imaging. Help is coming from various organisations, which are extending hands-on teaching and imparting knowledge, as well as training trainers to increase the pool of skilled practitioners in the use of imaging equipment and other aspects of radiology services. The scene for social radiology is changing and set to positively impact the world in the (near) future.

Interventional Radiology in Liver Transplantation  

SciTech Connect

Radiology is a key specialty within a liver transplant program. Interventional techniques not only contribute to graft and recipient survival but also allow appropriate patient selection and ensure that recipients with severe liver decompensation, hepatocellular carcinoma or portal hypertension are transplanted with the best chance of prolonged survival. Equally inappropriate selection for these techniques may adversely affect survival. Liver transplantation is a dynamic field of innovative surgical techniques with a requirement for interventional radiology to parallel these developments. This paper reviews the current practice within a major European center for adult and pediatric transplantation.

Radiology failure mode and effect analysis: what is it?  

PubMed

Proactive prevention of medical errors is critical in medical practice. Root cause analysis (RCA) is a conventional method used to deal with errors that result in an adverse event. However, RCA has several limitations. An analytic method for health care risk management, health care failure mode and effect analysis (FMEA), has been introduced relatively recently. Health care FMEA combines several existing analytic approaches into one simple tool with which to analyze a particular health care process, determine the risks associated with it, and develop corrective actions and outcome measures. The authors provide a brief history of health care FMEA, describe its validation process, and relate their experience with its use in a radiology department. PMID:19703888

Human Health and Ecological Risk Assessment for the Operation of the Explosives Waste Treatment Facility at Site 300 of the Lawrence Livermore National Laboratory  

SciTech Connect

This document contains the human health and ecological risk assessment for the Resource Recovery and Conservation Act (RCRA) permit renewal for the Explosives Waste Treatment Facility (EWTF). Volume 1 is the text of the risk assessment, and Volume 2 (provided on a compact disc) is the supporting modeling data. The EWTF is operated by the Lawrence Livermore National Laboratory (LLNL) at Site 300, which is located in the foothills between the cities of Livermore and Tracy, approximately 17 miles east of Livermore and 8 miles southwest of Tracy. Figure 1 is a map of the San Francisco Bay Area, showing the location of Site 300 and other points of reference. One of the principal activities of Site 300 is to test what are known as 'high explosives' for nuclear weapons. These are the highly energetic materials that provide the force to drive fissionable material to criticality. LLNL scientists develop and test the explosives and the integrated non-nuclear components in support of the United States nuclear stockpile stewardship program as well as in support of conventional weapons and the aircraft, mining, oil exploration, and construction industries. Many Site 300 facilities are used in support of high explosives research. Some facilities are used in the chemical formulation of explosives; others are locations where explosive charges are mechanically pressed; others are locations where the materials are inspected radiographically for such defects as cracks and voids. Finally, some facilities are locations where the machined charges are assembled before they are sent to the onsite test firing facilities, and additional facilities are locations where materials are stored. Wastes generated from high-explosives research are treated by open burning (OB) and open detonation (OD). OB and OD treatments are necessary because they are the safest methods for treating explosives wastes generated at these facilities, and they eliminate the requirement for further handling and transportation that would be required if the wastes were treated off site.

Salmonella enterica is commonly acquired from contaminated food and is an important cause of illness worldwide. Interventions are needed to control Salmonella; subtyping Salmonella by serotyping is useful for targeting such interventions. We, therefore, analyzed the global distribution of the 15 most frequently identified serovars of Salmonella isolated from humans from 2001 to 2007 in laboratories from 37 countries that participated in World Health Organization Global Foodborne Infections Network and demonstrated serotyping proficiency in the Global Foodborne Infections Network External Quality Assurance System. In all regions throughout the study period, with the exception of the Oceania and North American regions, Salmonella serovars Enteritidis and Typhimurium ranked as the mos
