【 摘 要 】

Findings from radioactivity and phytotoxicity study are presented for soils from nine study-sites of the Klintsovsky Forestry located in the Bryansk region that were radioactively contaminated after the Chernobyl accident. According to the bioassay based on barley as test-species, stimulating effect of the soils analyzed is revealed for biological indexes of the length of barley roots and sprouts. From data on137Cs specific activities in soils and plant biomass, the migration potential of radionuclide in the «soil-plant» system is assessed as a transfer factor. With correlation analysis, an impact of137Cs in soil on the biological characteristics of barley is estimated.
