CSR探测器在我国部分城市氡气测量中的应用

Radon measurements of some cities with CSR detectors

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。

The indoor and outdoor radon measurements in Haerbin and Yanan have been made with CSR detectors. At main measuring sites the balloon method has been used to measure the latent energy of daughters and the equilibrium factor. The results by the two methods have been compared and analysed. The measurements with CSR detectors indicate that the indoor radon concentration ranges from 16 to 144 Bq/m3 with an average of 73Bq/m3 in Haerbin, while from 13 to 78 Bq/m3 with an average of 35 Bq/m3 in Yanan. The results are compared with those with the balloon method, showing that the two methods are consistent within an error of 40%.
