为加强对新疆某县煤矿开采过程的放射性监管，通过对4家煤矿γ辐射剂量率、氡浓度及固体样品中放射性核素含量进行了调查与测量，估算了煤矿井下工作人员所受年有效剂量。监测结果表明：煤矿井上环境中γ辐射剂量率和氡浓度水平基本处于新疆及全国环境本底水平；煤矿井下环境中γ辐射剂量率和氡浓度水平偏高，数值波动范围较大，部分区域煤炭中存在放射性异常；煤矿工作人员所致年有效剂量分别为：A矿1．38 mSv，B矿0．69 mSv，C矿0．08 mSv，D矿0．61 mSv。评价结果表明：该区域4家煤矿煤炭中存在放射性问题，需加强对该矿区的辐射安全监管工作。

In order to strengthen the radioactivity supervision of coal mining process in a county in Xinjiang , 4 coal mines ’ γradiation dose rate , radon concentrations and naturally occurring radionuclides of solid samples were investigated and measured , the annual effective dose of the coal mine staff were estimated .The monitoring results showed that:theγradiation dose rate and radon concentration level of the coal mine ground environment were at the level of Xinjiang and the national environment background ;theγradiation dose rate and radon con-centration level of the coal mine underground environment were higher , the numerical fluctuation were great , and anomaly radioactivity existed in part of coal mines;the annual effective dose of the coal mine staff were:A mine 1.38mSv, B mine 0.69mSv, C mine 0.08mSv, D mine 0.61mSv.The evaluation results showed that the regional 4 coal mines had radioactive problems , and the radiation safety supervision work of the mines should be strengthened .
