Abstract: On the example of south-western districts of the Bryansk region, the article assess the dynamics of the coefficients of transfer of 137Cs in plants. Describes also the impact of protective measures on the accumulation of radionuclides in agricultural products. Distinguishes three periods decrease of 137Cs in the plant, during the 20 years after the Chernobyl accident. Shows the accumulation of the radionuclide-fallout, natural biogeochemical processes and protective measures to reduce the accumulation of 137Cs in agricultural plants for various periods after fallout. Describes forecast of maximum permissible levels of 137Cs contamination in agricultural land, on which it is possible to obtain crop products, meeting current standards, at different levels of protective measures in the contaminated areas. Estimates the period of time after the radioactive fallout, in which production of crops and forage production was provided, according to appropriate radiological standards.
