The concept of a dose-rate conversion factor for external exposure to photons and electrons and its application to the estimation of population dose following routine or accidental releases of radionuclides to the atmosphere were discussed. Dose-rate conv...
The dosimetric properties of some twenty textile fibers have been studied in order to develop a method for determining the dose received in the case of an accidental gamma irradiation. Three textile fibers having properties most closely satisfying our nee...
The damage to 13 workers following accidental exposures was assessed from lymphocyte chromosomal aberrations, and the results compared with those supplied by physical dosimetry and the clinical syndromes. (FR)

The application of lamp phosphors for accidental dosimetry is a new concept. Since the materials used in fluorescent lamps are good photo luminescent materials, if one can either use the inherent defects present in the phosphor or add suitable modifiers to induce thermoluminescence (TL) in these phosphors, then the device (fluorescent ...
The objective of this paper is to present a compilation of computer codes for the assessment of accidental or routine releases of radioactivity to the environment from nuclear power facilities. The capabilities of 83 computer codes in the areas of environmental transport and radiation dosimetry are summarized in tabular form. This preliminary analysis ...
Radiation-induced electron paramagnetic resonance (EPR) signals were first reported by Gordy et al. [Proc. Natl. Acad. Sci. USA 41 (1955) 983]. The application of EPR spectroscopy to ionizing radiation dosimetry was later proposed by Brady et al. [HealthPhys. 15 (1968) 43]. Since that time EPR dosimetry has been applied to accident and ...

The colorimetry and thermoluminescence properties of gamma irradiated glass were reported in as early as 1920. The utility of radio-photoluminescence (RPL) of silver activated metaphosphate glass for monitoring high doses of accidental and routine gamma radiation was reported in the 1960s. Since then considerable amount of research work has been carried out to study the ...
This work is a contribution to the study of stimulated exoelectronic emission, the goal of which is the development of a dosimetry available in case of accidental irradiation. The first part is devoted to a review of the various theoretical models suggest...
Among various biological dosimetry techniques, dicentric chromosome aberration method appears to be the method of choice in analysing accidental radiation exposure in most of the laboratories. The major advantage of this method is its sensitivity as the n...
This study has been developed to provide guidance to physicians on the handling of skin contaminations in some accidental circumstances. The first stage of diagnosis and consequently of the possible therapy in order to avoid or mitigate radiodermatitis is...
This is a comprehensive review and analysis of biokinetic and dosimetric information for those radionuclides most likely to be involved in accidental exposures to workers or members of the public or used in radiological terrorism.
In the scope of the IDEAS project to develop General Guidelines for the Assessment of Internal Dose from Monitoring data, two databases were compiled. The IDEAS Bibliography database contains references dealing with problems related to cases of internal contamination. The IDEAS Internal Contamination Database now contains more than 200 cases of internal contamination. In the near future, the IDEAS ...
There is a growing public awareness of the risk of accidental radiation exposure due to ageing nuclear power installations, illegal dumping of nuclear waste and terrorist activities, and of the consequential health risks to populations in addition to social and economic disturbance extending beyond national boundaries. In the event of catastrophic incidents where no direct ...
The CONRAD Project is a Coordinated Network for Radiation Dosimetry funded by the European Commission 6th Framework Programme. The activities developed within CONRAD Work Package 5 ('Coordination of Research on Internal Dosimetry') have contributed to improve the harmonisation and reliability in the assessment of internal doses. The tasks carried out ...
Decay data are presented for approximately 500 radionuclides including those occurring naturally in the environment, those of potential importance in routine or accidental releases from the nuclear fuel cycle, those of current interest in nuclear medicine and fusion reactor technology, and some of those of interest to Committee 2 of the International Commission on Radiological ...
Commercial glasses have been investigated for their application in accidental gamma dose measurement using Thermoluminescent (TL) techniques. Some of the glasses have been found to be sensitive enough that they can be used as TL dating material in radiological accident situation for gamma dosimetry with lower detection limit 1 Gy (the ...
In this text we give the dosimetry principle on irradiated materials such baffle screw, pressure vessel and control element cans. This measure, made by gammametry, is based on the steel activation and comparison with calculated measures by Actige code. 4 ...

Scoring of micronuclei in cytokinesis-blocked peripheral human lymphocytes, after an accidental overexposure, seems an easier and faster alternative for biological dosimetry than conventional cytogenetics (dicentric chromosomes). Several variations of the...
A new sort of thermoluminescent phosphor has been developed with the purpose of enlarging the range of linear dose-response. The thermoluminescence properties of CaSO(4):Tm,Cu, prepared according to our method, were studied in the dose range of 0.5 Gy-125.0 kGy. The results of the present work show that the CaSO(4):Tm,Cu is an excellent new dosimetric material due to its relatively simple glow ...
The analysis of luminescence of minerals extracted from pottery and bricks is a well-known tool in retrospective dosimetry. In the past, the detection limit of this method has been reported to lie in general in the order of magnitude of about 10 mGy. For most applications in accidental dosimetry, this is more than ...
