CONTAMINATION OF FUNGI WITH RADIONUCLIDES AFTER ACCIDENT ON CHERNOBYL NPP

Natalia Zarubina

Abstract


Impact of the accident on Chernobyl Nuclear Power Plant on pollution of fungi within the 30-km alienation zone and within the Kiev region has been studied. Fungi accumulate practically all radionuclides produced by the accident. Dynamics of the accumulation of 137Cs by fungi has two phases. Main factors that produce significant impact on the specific activity of 137Cs in fungi are: levels of soil contamination by this radionuclide, ecological group of the mushroom species and depth of mycelium in soil. Variations of 137Cs content during vegetation period have been observed.
