| Abstract: | The dynamics of 137Cs uptake by crops and the influence of rehabilitation measures on the accumulation of this radionuclide in agricultural products have been estimated by the example of southwestern regions of Bryansk oblast. In 20 yr after the Chernobyl NPP accident, three stages of a decrease in the concentration of 137Cs in the crops can be distinguished. At present (in 15–20 yr after the accident), the rate of the decrease in the concentration of 137Cs in some crops corresponds to the half-decay period of this radionuclide. |
