Краткое описание

The article presents chamber models of radionuclides 90Sr and 137Cs content dynamics in abiotic and biotic components of the Gluboke and Daleke lakes of the Chornobyl exclusion zone. The forecast was made for the transition of the considered radionuclides from the catching area to water and bottom sediments, their accumulation by the reed biomass over 20 years since 2000. Two periods of the radionuclides' redistribution were stated - period of intensive changes and period of dynamic equilibrium. It has been established that 137Cs is accumulated by the reed tissues more intensively than 90Sr. Over short period of the dynamic equilibrium almost half content of 90Sr and 137Cs is accumulated, which could transit to the reed biomass over 20 years.
