Radionuclides accumulation by berry bushes in forest ecosystems of Yenisei river basin

In work investigated accumulation of radionuclides in 5 kinds of berry bushes from flood plain forests of Yenisei river (Krasnoyarsk region). Have been defined specific activity of 60Co, 90Sr, 137Cs, 238U and tran-suranium elements in elevated bodies of bushes and their factors of accumulation (КН) are calculated. The analysis of calculated КН has shown that bushes in the greatest degree accumulate 90Sr (КН=0,25- 1,9). The maximum accumulation of 137Cs is characteristic for Ribes nigrum and Rubus idaeus berries and leaves. For these kinds the range of values КН of 137Cs (0,006-0,027) is crossed with range КН of 238U (0,004-0,018). Received range КН of transuranium radionuclides (0,01-0,056) for elevated bodies of Ribes nigrum is comparable or above КН of 238U and 137Cs.
