RÉSUMÉ

137Cs specific activity in fishes differing in the type of their nutrition was studied in 1978−2013 in the cooling pond of the Chernobyl NPS. Long-term dynamics of the fluctuations in 137Cs specific activity in 13 species of fishes are given in the paper. The coefficient of inversion (Kinv) reflecting changes (inversions) in 137Cs specific activity over any period was calculated in assessing dynamics of 137Cs specific activity in fishes. The highest specific activity of 137Cs is registered in fishes of high trophic levels. From 1986−1987 until 2012−2013 the specific activity of 137Cs in fishes decreased almost by a factor of 100. The most intensive decrease in the specific activity of 137Cs is typical to fishes of low trophic levels. In 2011−2013 in the cooling pond of the Chernobyl NPS in the studied species of fishes, the specific activity of 137Cs ranged from 0.8 to 7.6 kBq/kg.
