Abstract: Dynamics of 137Cs accumulation by marketable fishes in different kinds of water bodies (cooling pond, water reservoir, lake) polluted by radionuclides after the Chernobyl accident has been studied. The highest concentration of 137Cs, reaching 500 kBq/kg w.w. (wet weight) was registered in fish inhabiting the cooling pond of ChNPP in 1986. During the last 15 years the level of radionuclides in fishes of all water bodies came down, but rates of lowering are different.
