摘　　要：对乌鲁木齐某实验楼室内氡浓度的测量结果表明,该实验楼室内氡浓度在39~137 Bq/m^(3),平均76.1 Bq/m^(3),吸入氡及其子体对相关人员的年均有效剂量为0.51~0.68 mSV,平均值为0.57 mSV,高于乌鲁木齐平均水平,推测与研究区活动断层出露有关。分析数据显示,研究区地下土体扩散氡对一层室内氡浓度影响较大,导致一层室内氡浓度较高,且室内氡浓度在一定程度上受到房屋朝向影响。并结合影响因素,有针对性的提出了预防和降低室内氡浓度的措施。In this paper,the indoor radon concentration of an experimental building in Urumqi was observed.The observation results show that the indoor radon concentration of the experimental building is 39~137 Bq/m^(3),with an average of 76.1 Bq/m^(3).The annual effective dose of radon to human body is 0.51~0.68 mSv,with an average of 0.57 mSv,which is higher than the average level of Urumqi.It is supposed to be related to the exposure of active faults in the study area.The analysis data show that the radon diffusion in the underground soil has a great impact on the indoor radon concentration in the first floor,which leads to a higher indoor radon concentration in the first floor,and the indoor radon concentration is affected by the house orientation to a certain extent.Combined with the influencing factors,the measures to prevent and reduce indoor radon concentration are put forward.
