为摸清调查区水放射性环境现状,在重点煤炭开发区给资源开发利用与辐射污染防控决策提供基础参考数据,通过对区内河水、泉水、井水、煤矿坑道排水、水文地质长期观测孔内水等水源采样进行放射性核素含量分析,结合前人的调查成果,共发现地下水水铀异常点13个、水氡异常点10个,圈定地下水水铀异常晕8片、水氡异常晕5片.分析认为水放射性异常的形成多与附近发育的铀矿化有关,今后其附近地下水开发利用需开展进一步放射性环境评价.%In order to find out the water radioactive geological environment of the key coal development zone,and provide the basic reference data for the development and utilization of resources and the prevention and control of radiation pollution,after analyze the content of radionuclide on sample of the river water,spring water,well water,drainage of coal mine tunnel and water in the Long term observation hole in hydrogeology in investigation area,and combined with the previous research findings collected,We found 13 Uranium anomaly points of groundwater,10 Radon anomaly points of groundwater;and delineats 8 pieces of halo anomaly of groundwater water Uranium,5 Radon pieces of groundwater anomaly halo.We analyze that the formation of water radioactive anomalies is closely related to the uranium mineralization nearby,so it is necessary to carry out radioactive environment assessment for the development and utilization of groundwater nearby in the future.
