Ecological Systems and Devices Annotation << Back Specification of power range of applicability of the method of local fluence estimation for problem of carrying over of photon irradiation in the air Elokhin A.P., Zhilina M.V. We consider the range of applicability of the Method of Local Fluence Estimation (the Monte Carlo Method) that is used for evaluation of external irradiation dose rate from a point isotropic source of photon irradiation which appears in the premises of reactor block in case of radiation accidents at NPPs. Radial distributions of buildup factor BD(?d, E0) are received as a function of ?-irradiation energy (E0) and distances source-detector (?d). E-mail: elokhin@yandex.ru
