The regularities are studied of the decontamination of agricultural ecosystem components from 137Cs deposited after the Chernobyl accident in a number of regions of Russia with different soils and climatic conditions.
During the first 5-6 years after the deposition, it has been shown that the content of this radionuclide in vegetable and animal agricultural products decreased with the half-period 0.7 to 1.5 years.
Beginning from 1990-1991, no significant variation of 137Cs content in food products was found, and the values of the transfer factors for this radionuclide in the main components of the food of rural inhabitants (milk, potatoes) were close to the corresponding parameters obtained in the pre-accident period (1980-1985) for 137Cs of global origin.
