Neutron Radiation from Medical Electron Accelerators*
Electron accelerators operating above about 10 MeV produce significant quantities of photoneutrons. This is not a new problem and was first reported by Laughlin1 in 1951 for a 23 MeV betatron. In recent years it has drawn considerable attention because of the increased use of higher-energy electron linear accelerators for radiation therapy and also because of the increased awareness of radiatio...
متن کاملUnexpected dose and the biological effect of neutron contamination in linear accelerators
Employing High-energy photons in medical linear accelerators can lead to neutron contamination. The relative biological effect of neutrons is 20 times higher than photons. Consequently, its damage to the biological tissue is much higher and unobtrusive. In this study, we calculated neutron equivalent dose in a medical linear accelerator by the FLUKA Monte Carlo code system. The results show tha...
متن کاملMedical Applications of Electron Linear Accelerators
The role of radiation therapy in cancer management is first defined: today among the cancer patients who are cured (≅ 45 %) about one half are cured by radiation therapy applied alone or in combination with surgery or chemotherapy. The experience accumulated in decades shows that, to be efficient, the radiation treatment must be delivered with a high physical selectivity. At present, electron l...
متن کاملOptimal Fast Neutron Sources Using Linear Electron Accelerators
Fast neutron sources are designed and experimentally tested, based on optimized conversion targets and linear accelerator as electron suppliers. Both gamma radiation and fast neutron emissions are studied, establishing the most effective characteristics of the targets in terms of material, spatial dimensions, relative position of target and source, incident electron energy. A numerical procedur...
متن کاملRadiation protection at high energy electron accelerators.
An overview is presented of radiation protection at high energy electron accelerator facilities. By 'high energy' is meant the energy domain beyond a few tens of MeV, where electromagnetic showers are the determining and dominant factor for beam interactions with matter. The basic components of electron accelerators are described and their potential impact on radiation safety. The paper then co...
