T1 Mechanisms of Forming of Seasonal Variations of 90Sr and 137Cs Content in the Freshwater Fishes JF Hydrobiological Journal JO HYD YR 2013 FD 2013-10-02 VO 49 IS 5 SP 81 OP 89 K1 freshwater fishes K1 90Sr K1 137Cs K1 seasonal variations K1 mathematical modeling AB Mechanisms of seasonal changes of 90Sr and 137Cs content in body of the freshwater fishes were studied by the methods of mathematical modeling. The maximum range of the seasonal variations of 90Sr in fishes was found to be equal to 17% of the annual mean, 137Cs − 50%.
