Vertical migration of 137Cs and 90Sr in soils of abandoned land and their availability to plants

The research of the migration of 137Cs and 90Sr radionuclides in agricultural soils appears a serious scientific and practical problem. Parameters of vertical migration of radionuclides upon soil profile represent the base for forecasting of radiation accumulation in agricultural production. The mai...

Description
Summary:The research of the migration of 137Cs and 90Sr radionuclides in agricultural soils appears a serious scientific and practical problem. Parameters of vertical migration of radionuclides upon soil profile represent the base for forecasting of radiation accumulation in agricultural production. The main goal of the research, presented in the article, is investigation of the migration of 137Cs and 90Sr in the 'soil-plant' system for forecasting of self-purification of uncultivated lands upon generalization of observational information for the period since 1986 (the date of Chernobyl accident) up to our time. The article demonstrates the results of monitoring of 137Cs and 90Sr vertical migration in the profile of different soils that are not used after the Chernobyl accident. The quantitative composition, distribution of radionuclides in the layers of soils with different genesis, texture and moisture regime as well as radionuclide transfer into perennial grass stands are presented. Discussed is the use of the obtained data for prediction of self-purification of upper root-containing soil layers (0–10 cm) and availability of radionuclides to plants.
