| 摘 要： | 浙江西部山区石煤资源丰富，广泛地被应用于石煤制品的生产和用做部分电厂、山区农村的燃料。石煤中U、Th等放射性核素含量高，致使部分石煤及其制品中U、Th等放射性核素含量偏高。U、Th是Rn的母体元素，衰变后不断释放出氡气，导致石煤产区居室内氡浓度和居民年辐射剂量当量严重超标，危害人体健康。本文在分析该区部分石煤产区、石煤制品、石煤电厂以及居室中的放射性元素污染的基础上，提出了相应的防治措施。

| Abstract: | Western Zhejiang is very rich in boun (stone) coal resources. It is widely used in the manufacturing of boun coal products and as fuel in some power plants and in villages of mountainous areas. However, the contents of radioactive nuclides such as uranium, radium and thorium are high in some boun coal and its products. Uranium and thorium are parent elements of radon. They release radon gas unceasingly after decay, polluting the atmosphere and environment of dwelling rooms. The radon concentration in dwelling rooms and the annual radiation dose equivalent of the habitants in the mining areas greatly exceed the standards, to the detriment of the human health. On the basis of an analysis of the pollution of radioactive elements in boun coal mining areas, boun coal power stations, its products and dwelling rooms, this paper puts forward corresponding counter-measures. |
