Assessment of radioactivity of the Sobirsoy reservoir and adjacent areas of the Nurabad district, Uzbekistan

Abstract Reservoirs and artificial channels are vital sources of water for irrigated areas in arid and semi-arid regions. As such, monitoring the radioecological state of these water bodies is crucial for public health and safety. In this study, we aimed to evaluate the radioecological condition of the Sobirsoy reservoir and surrounding areas. We used gamma-spectrometry to measure natural and anthropogenic radionuclides, and coal sorbents to measure radon flux density on the ground surface. Based on our findings, we conducted a radiological risk assessment and compiled an exposure dose map of the study area. The results showed that the degree of radioactive danger to people in populated areas is within safe limits. Overall, our study provides important information for policymakers and stakeholders to make informed decisions regarding the management and safety of the Sobirsoy reservoir and its surroundings.
