Abstract

The accumulation of anthropogenic radionuclides ⁹⁰Sr and ^134,137Cs 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 ¹³⁴Cs and ¹³⁷Cs 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 ⁹⁰Sr and ¹³⁷Cs 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.

放射性核素在核植物区的沼泽蛙Pelophylax ridibundus中的积累

摘要

在Beloyarsk水库（Beloyarsk核电站的冷却池）中，研究了在不同发育阶段的沼泽蛙中⁹⁰ Sr和^134,137 Cs的人为放射性核素的积累。Verkhnetagilsk水库充当对照（参考地点）。记录了所研究水体的成年两栖动物的个体形态指标和放射性核素浓度的变异性。¹³⁴ Cs和¹³⁷的异常高污染在别洛雅尔斯克水库的工业洪水通道中的一只青蛙中发现了铯，这可能是由于动物与核电厂区域中的放射性介质之间的接触所致。据揭示，目前，在别洛雅尔斯克水库的某些观测点，青蛙中⁹⁰ Sr和¹³⁷ Cs的蓄积水平显着高于对照水库。但是，青蛙中放射性核素的浓度远低于两栖动物的允许水平。
