本文介绍了哈尔滨、延安等城市应用CSR探测器对室内、外氡进行测量,并在主要测点上使用气球法进行氡及子体α潜能、平衡因子测量,并比较分析两种方法测定结果的差异。固体径迹探测器测定结果:哈尔滨市室内氡浓度范围为16—144Bq/m~3,均值为73Bq/m~3;延安市的范围为13—78Bq/m~3;均值为35Bq/m~3。与气球法测定结果进行了比较,两种方法测定结果偏差在40％以内相一致。 This paper introduces the application of CSR detectors in Harbin, Yan’an and other cities to measure indoor and outdoor radon, and uses the balloon method to measure the alpha potential and balance factor of radon and progeny at the main measuring points, and compares the results of the two methods difference. The results of solid track detector showed that the indoor radon concentration ranged from 16-144Bq / m ~ 3 in Harbin with an average value of 73Bq / m ~ 3, that in Yan’an ranged from 13-78Bq / m ~ 3, with an average of 35Bq / m ~ 3. Compared with the balloon method, the results of the two methods are within 40%.
