摘    要:本文给出采用被动式活性炭室内~(222)Rn 累积探测方法对北京市220个地下建筑室内平均~(222)Rn浓度的测量结果。除天然溶洞外,198个地下建筑物内~(222)Rn 浓度呈对数正态分布,其算术平均值为1.10pci/1,几何均值和几何标准差分别为0.79pCi/1和2.3。在该地下建筑物中生活的居民及工作人员由于吸入~(222)Rn 及其短寿命子体所致年有效剂量当量分别为1.39mSv 和1.20mSv,比地面建筑物内相应人群分别高31%和13%。

关 键 词:地下建筑物  氡浓度  剂量

Abstract:The measurement results of the average Radon concentrationin 220 underground buildings in Beijing by the passive integrating activatedcharcoal method are given.Except nature cave,the indoor Radonconcentrations in 198 underground buildings appear a lognormal distribution.Geometric mean and geometric standard deviation are 0.79 pCi/L and 2.3respectively,arithmetic mean is 1.10 pCi/L.The annual effective doseequivalent of population and occupation in the underground buildings dueto exposure to Radon and its daughters are 1.39 mSv and 1.20 rosvrespectively,31% and 13% more than that of corresponding groups in thegorund buildings respectively.
Keywords:Underground Building  Radon Concentration  Dose
