对乌鲁木齐市具有代表性的民用住宅室内氡浓度进行了连续一年的监测调查，调查结果显示室内氡浓度平均值55.4 Bq／m3，低于国标的“200 Bq／m3”，并据此估算出其所致居民的年均有效剂量为1.400 mSv，以及所致居民支气管上皮组织、肺、性腺、骨髓及骨表面细胞等关键组织的年吸收剂量分别为1886．49，378.96，2.80，3.20，3.20μGy／a，大于UNSCEAR2000年报告的世界平均值1.008 mSv，结合室内氡的主要来源，提出了对建筑材料进行放射性监测、控制装修、工程竣工后开展室内环境监测、加强室内通风以及开展室内氡污染治理等措施控制室内氡浓度水平。

This study monitored the indoor radon concentration of typical residential areas in Urumqi for one year .The aver-age value for indoor radon concentration is 55.4 Bq/m3 , lower than the national standard 200 Bq/m3;and the estimated average annual effective dose is 1.400 mSv.It is calculated that the absorbed dose in bronchial epithelial tissue, lung, gonads, and bone marrow cells of local residents were 1 886.49 uGy/a,378.96 uGy/a,2.80 uGy/a,3.20 and 3.20 uGy/a, which is greater than the world average 1.008 mSv indoor radon level reported in UNSCEAR 2000 report.Combining with the main source of indoor ra-don, this paper proposed to run indoor environment test on radioactive materials and control decoration after completion of the pro-ject to enhance indoor ventilation and conduct indoor radon pollution control measures to control indoor radon pollution .
