ABSTRAKT

The content of 137Cs in 20 species of fishes of the Kanev Reservoir belonging to different ecological groups was studied during 2007. In all the species of fishes, the content of 137Cs was significantly lower than its limiting permissible content according to the norms accepted in Ukraine. It did not exceed 35 Bq/kg. The highest content of 137Cs was observed in predatory fishes and in fishes with the mixed type of nutrition, whereas its lowest content was registered in benthos-, plankton-, and phytophagous species of fishes.
