Abstract

Results of study of radionuclides transfer from soil to plants in the area for testing radiological warfare substances ("4a" site) are presented in the article. Accumulation factors for 241Am, 137Cs and 90Sr are given in the paper. Difference in the accumulation of 90Sr by some plants was observed. Accumulation factor for 137Cs and 90Sr characteristic for the area under study and internationally recognized data were compared.

Key words
Semipalatinsk Test Site (STS), radioecology, radiocontamination, 241Am, 137Cs, 90Sr, soil, plant, accumulation factors (AF).
