Lebed O. Substantiation of assessment of ecological risk for inhabitants from the receipt of radon to the houses of the city of Rivne

The subject of research is the phenomenon of radon entry into homes and the formation of individual induced environmental risk for the population of Rivne. The subject of the study is indicators that characterize the effects of radon flow into homes and the quantitative and qualitative assessment of environmental risk for a city dweller. Scientific novelty of the obtained results. Based on the generalized data of radon content in the air of the buildings of the city: for the first time in the territory of the city zones of high environmental risk were established; a scale of quantitative and qualitative assessment of environmental risk for city dwellers to homes has been developed based on significant differences in radon concentration in ground air, in-house air and radon flux density from soil; methods for determining the concentration of radon in atmospheric air and water, the density of radon flux from soil have been improved; calculation of environmental risks (constant proportional, Jacobi, BEIR-IV and BEIR-VI in two variants (AID and AIC)) using exposure to radon OA and its decay products; the risk of morbidity and mortality of the city population for lung cancer, depending on the concentration of radon in the air of the premises and the method of calculation of individual radiation damage and potential radiation damage to the city population.proposed measures to reduce environmental risks for residents (for example, Rivne);The practical significance of the obtained results is: the allocation of environmental risk categories in the city and the area of ??radon concentration in homes. Areas recommended for the use of a map of territories with the definition of risk zones for the population. Developed recommendations and management decisions to improve the environmental status of the city.
