Accumulation of Radionuclides in the Marsh Frog Pelophylax ridibundus in the Zone of a Nuclear Plant

The accumulation of anthropogenic radionuclides 90 Sr and 134,137 Cs in the marsh frog at various stages of ontogenesis is studied in the Beloyarsk Reservoir (cooling pond of the Beloyarsk nuclear plant). The Verkhnetagilsk Reservoir serves as a control (reference site). The variability of individua...

Description
Summary:The accumulation of anthropogenic radionuclides 90 Sr and 134,137 Cs in the marsh frog at various stages of ontogenesis is studied in the Beloyarsk Reservoir (cooling pond of the Beloyarsk nuclear plant). The Verkhnetagilsk Reservoir serves as a control (reference site). The variability of individual morphological indicators and concentrations of radionuclides in adult amphibians of the studied waterbodies is noted. An abnormally high contamination of 134 Cs and 137 Cs is revealed in one frog from the industrial flood channel of the Beloyarsk Reservoir, which may be due to contact between the animal and a radioactive medium in the area of the nuclear plant. It has been revealed that, currently, at some observation points of the Beloyarsk Reservoir, the levels of 90 Sr and 137 Cs accumulation in the frogs are significantly higher than in the control reservoir. However, the concentration of radionuclides in frogs is much lower than the permissible level for amphibians.
