摘要：

The results of the assessment of levels of radionuclide contamination of fish during 2013 - 2019 in the reservoirs of the Chornobyl Exclusion Zone (lakes Azbuchyn, Vershyna, Hlyboke, Daleke, Yanivsky Backwater, Chornobyl NPP cooling pond) are presented. It was found that the concentration of Cs-137 in representatives of ichthyofauna of water bodies during the study period continued to decrease, while the concentration of Sr-90, with some exceptions, remained unchanged or increased. The concentration of radionuclides in fish of the studied reservoirs was about 60 - 5000 times for Sr-90 and in 3 - 200 times for Cs-137 higher than the permissible levels for fish products accepted in Ukraine.
