摘要: 为了了解西安地铁一号线和地铁二号线车站空气中氡浓度水平现状,采用Model 1027连续测氡仪对西安市两条地铁线路车站内氡浓度进行了监测,按照联合国原子辐射效应科学委员会推荐的评价方法估算了车站内氡及其子体所致地铁工作人员人均年有效剂量。监测结果表明,西安市地铁一号线全线氡浓度平均值为60.27 Bq/m3,地铁二号线全线氡浓度平均值为32.54 Bq/m3。地铁一号线和二号线车站内工作人员由氡及其衰变子体所致人均年有效剂量分别为0.63 mSv/a和0.34 mSv/a,低于国家标准规定的工作人员年有效剂量限值。

Abstract: In order to understand the current level of air radon concentration in Xi'an subway stations, radon concentration levels in the Xi'an subway stations of Line 1 and Line 2 were monitored using Model 1027 continuous radon monitor, and radiation exposure to subway staff was assessed according to evaluation methods recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation. The monitoring results show that the average radon level at stations of Line 1 is 60.27 Bq/m3 and 32.54 Bq/m3 for Line 2. The annual effective dose of air radon to staff in Line 1 and Line 2 stations is 0.63 mSv/a and 0.34 mSv/a, respectively, which are lower than the recommended safe value.

Key words: subway, radon concentration, radiation exposure, Xi'an
