Assessment of accumulation of technogenic radionuclides strontium-90 and caesium-137 by fish of the vilia river
Abstract
Studies have been conducted on the accumulation of technogenic radionuclides strontium-90 (Sr90) and caesium-137 (Cs137) in some fish species of the Vilia River, at sites of water intake and discharge sites of the Belarusian NPP. The activity of accumulation of Sr90 and Cs137 in the body of fish with different types of nutrition has been studied. An analysis of the results of radiological studies in 2023 showed that the content of radionuclides in the fish of the Vilia River does not exceed acceptable standards and as a food product it is safe for humans. This work represents an important stage in monitoring the environmental safety of reservoirs adjacent to nuclear power facilities. Taking into account the urgency of radiation protection and environmental control issues, special attention was paid to assessing the possible impact of the Belarusian NPP on aquatic organisms. The data obtained allow us to assess the degree of accumulation of radionuclides in the trophic levels of the ecosystem, and also give an idea of the effectiveness of natural mechanisms of self-purification of the aquatic environment. Additionally, the results of the study can be used in further environmental assessments and the development of recommendations for the sustainable use of water resources. Thus, the conducted analysis contributes to the formation of a holistic picture of the radiation background in the studied area and can serve as a basis for making managerial decisions in the field of environmental protection.
