Accumulation of 137Cs in a pike perch (Lucioperca lucioperca L.)

Abstract

Long-term researches of specific activity of 137Cs at a pike perch (Lucioperca lucioperca L.) from Kanevskoe reservoir and cooling-pond of ChNPP are summed up. Distribution of 137Cs on organs and tissues of a pike perch occurred more slowly, than at the majority of other species of fishes. It is established that water temperature does not influence on specific activity of 137Cs at a pike perch. Increase of specific activity of 137Cs at a pike perch with increase in weight of the individual is registered. Dynamics of decrease of specific activity of 137Cs and dy-namics of factors of accumulation of 137Cs by a pike perch in different reservoirs can significantly differ.
