RADON HAZARD IN UKRAINE IN THE CONDITIONS OF RECONSTRUCTION AND URBANIZATION
Abstract. The topic of the study was chosen due to the high relevance of the problem that arises during the reconstruction, restoration and additional construction of urban infrastructure, in particular underground bomb shelters and shelters. In the current security situation, the population of Ukraine is forced to stay in such premises for a long time, which creates an increased risk to health. Due to direct contact with soil layers and insufficient ventilation, radon concentrations in underground premises can significantly exceed recommended levels, which potentially increases the risk of developing respiratory diseases, primarily lung cancer. The experience of other countries shows that after the end of hostilities, the construction of additional underground shelters is planned as part of strategic measures to improve the safety of the population and rebuild cities. The purpose of this study is to analyze the main dangers associated with radon, as well as the mechanisms of its accumulation in residential and underground premises in the context of modern urbanization. The work included a review of scientific data on the properties of radon and its impact on human health, an analysis of current regulations and standards for controlling radon concentrations in premises in accordance with the legislation of Ukraine, identification of the main routes of radon penetration and effective methods of its prevention, as well as measurements of volumetric activity (OA) and calculation of equivalent equilibrium volumetric activity (EROA) of radon-222 decay products at 4 measurement points located on the territory of the Ukrainian Crystalline Shield. Particular attention was paid to assessing the relevance of the problem not only in current conditions, but also in the future, taking into account plans for further urbanization and infrastructure restoration, which includes the construction of new underground structures and shelters.
Keywords: radon, volumetric activity, equivalent equilibrium volumetric activity, measurements, radon concentration in the air, decay products.
