Resumo

The paper presents the data on the content of plutonium (239,240Pu) in the muscles of the Baikal grayling Thymallus baicalensis, inhabiting the middle reaches of the Yenisei River in the vicinity of the radioactive discharge point of the Mining and Chemical Combine, in 2011–2019. The content of 239,240Pu in grayling muscles varied within 7–32 mBq/kg dry weight. Highest value was recorded in 2019, a year after the increase in the volume of controlled plutonium discharges. The ratio of activity concentrations 239,240Pu/137Cs in grayling muscles compared to the similar ratio in other hydrobionts of the Yenisei indicates a lower bioavailability of plutonium for fish.
