Comparative analysis of radon sources'contribution into total radon indoor levels for Altai and Tomsk regions of Russian Federation

摘要

The analysis of climatic, geological and architecture features of two regions was carried out from radon potential point of view. Altaiskii Krai and Tomsk Oblast are situated in the south of West Siberia. Therefore, the continental climate with a high dynamics of climatic and ecological parameters is typical for both regions. Architecture and building material types are alike in many aspects. However, geological features of these regions differ substantially. This may cause a difference in distributions of radon levels in buildings. Radon levels inside buildings of rural and urban types were measured using SSNTDs, charcoal canisters and radon-monitors Alpha-GUARD PQ2000 (confirmative measurements). Exposure periods were 1-3 months in different year seasons. The experimental results were statistically analyzed. The contributions of main radon sources into total level were revealed and the gradation of sources was made. The results of the comparative analysis and discussion are presented in the paper.
