The disposal of industrial waste presents major logistical, financial and environmental issues. Technologies that can reduce the hazardous properties of wastes are urgently required. In the present work, a number of industrial wastes arising from the cement, metallurgical, paper, waste disposal and energy industries were treated with accelerated ...

The vast majority of radiation treatments for cancerous tumors are given using electron linacs that provide both electrons and photons at several energies. Design and construction of these linacs are based on mature technology that is rapidly becoming more and more standardized and sophisticated. The use of hadrons such as neutrons, protons, alphas, or ...

Heavy-ion therapy is one of the important methods for the cancer treatment. More than 3400 patients were treated between 1994 and 2007 at Heavy Ion Medical Accelerator in Chiba (HIMAC). For the promotion of carbon-ion therapy, a compact carbon-therapy facility was developed. The size of the new facility is three ...
Hadrontherapy with protons and carbon ions is a fast developing methodology in radiation oncology. The accelerators used and planned for this purpose are reviewed starting from the cyclotrons used in the thirties. As discussed in the first part of this paper, normal and superconducting cyclotrons are still employed, together with synchrotrons, for proton ...
Basic phenomena in irradiations of X-ray and particle beams and comparison among various radiations are described. Total doses and fractionations for several sites in case of carbon beam are shown in comparison with X-ray and proton beam. Typical results of carbon beam treatments are shown. Original facility was too large. Then, ...
The increasing volumes of municipal solid waste produced worldwide are encouraging the development of processes to reduce the environmental impact of this waste stream. Combustion technology can facilitate volume reduction of up to 90%, with the inorganic contaminants being captured in furnace bottom ash, and fly ash/APC residues. The disposal or reuse of these residues is however governed by the ...
S>An electron therapy technique is described for treating large field superficial lesions, particularly mycosis fungoides. An x-ray linear accelerator was modified to permit convenient, rapid, and routine conversion to this treatment modality with minimum interference to a large supervoltage therapy program. Information is presented on ...
Mineral carbonation provides a potential option for the long-term storage of carbon dioxide. Serpentine has been chosen as the feedstock mineral, due to its abundance and availability. However, the relatively low reactivity of serpentine has warranted research into physical and chemical treatments that have been shown to greatly ...
Carbon ion beams have superior dose distribution allowing selective irradiation to the tumor while minimizing irradiation to the surrounding normal tissues. Furthermore, carbon ions produce an increased density of local energy deposition with high-energy transfer (LET) components, resulting in radiobiological advantages. Stimulated by the favorable results ...
The present study focuses on the application of an aqueous phase accelerated carbonation treatment on air pollution control (APC) residues from municipal solid waste combustion, aimed at assessing its influence on the environmental behaviour of the residue under concern, as well as the potential of the process in terms of sequestration ...
Fabrication of carbon stripper foils and their performance in electrostatic accelerators are described. (GHT)
The Heidelberg Ion Therapy Facility (HIT) is the first dedicated proton and carbon therapy facility in Europe. It uses full three dimensional intensity controlled raster scanning as basic treatment technique. Commissioning of the accelerator with beam was successfully finished for three fixed beam places in April 2008. A library of ...
The Heavy Ion Medical Accelerator in Chiba (HIMAC) is the world's first heavy ion accelerator complex dedicated to medical use in a hospital environment. Heavy ions have superior depth-dose distribution and greater cell-killing ability. In June 1994, clinical research for the treatment of cancer was begun using ...
Different artificial ageing treatments were applied to fresh incinerator bottom ash with the aim of promoting/accelerating the natural reactions occurring over time on the mineral phases in the material. The weathering treatments included accelerated carbonation, treatment ...
The purpose of this study was to estimate the financial costs to start BNCT as a clinical treatment in a hospital. To evaluate more accurate data on the precise costs of BNCT, we analyzed the costs of conventional radiotherapy, carbon ion and proton therapy and compare them to BNCT. An aggregate cost calculation of accelerator, ...
The concomitant recycling of waste and carbon dioxide emissions is the subject of developing technology designed to close the industrial process loop and facilitate the bulk-re-use of waste in, for example, construction. The present work discusses a treatment step that employs accelerated carbonation to convert ...
