Abstract
The main ways of radiation risks assessment are considered: linear threshold-free model and practical threshold model. New approaches to selection of radiation risk assessment threshold based on comparison of man-made exposure doses with lifetime exposure doses from natural radiation sources are proposed. The threshold of risk assessment for exposure to radon daughter products equal to 30 Bq/m3 has been proposed. Using both threshold-free and threshold models the estimates of radiation risk for the population of Sverdlovsk region exposed to natural and anthropogenic sources were made. It is shown that the contribution of technogenic training is much lower than that of permanent radiation factors - radon and medical diagnostic irradiation.
