中文摘要：

采用固体核径迹法，对成都市不同建筑类型、建筑结构、装修材料以及不同楼层的100间居室进行了室内氡浓度测量。调查结果表明：成都市居室环境中氡浓度的最高值为177．1Bq／m3,最低值为8．4Bq／m3,算术平均值为（39．4±22．9）Bq／m3；不同类型房屋室内氡浓度水平有显著差异；氡及其子体照射所致的人均年有效剂量为0．99mSv，低于世界平均水平。

英文摘要：

Solid state nuclear track method was used to measure indoor radon concentrations in 100 rooms of different construction structures, decoration materials and floors in Chengdu. The results showed that the highest level of indoor radon concentration in Chengdu is 177.1 Bq/m3, the lowest level is 8.4 Bq/m3, and the average level is （39.4 ±22.9） Bq/m3; Statistical analyses showed that the differences of indoor radon concentration among different types of building were significant; Radon and his daughter＇s annual effective dose to shine is 0.99 mSv, lower than world average.
