摘　　要：室内氡浓度会对人体健康造成重大影响,为全面了解银川市(三区两县)室内氡浓度水平及对公众辐射有效剂量,该研究使用RAD7测氡仪对银川市(三区两县)15处居室进行连续12个月的监测,并对监测数据进行统计分析和综合研究。监测结果显示银川市(三区两县)居室内氡浓度水平在3.04~144 Bq/m3之间,算数平均值为55.89 Bq/m3,高于世界平均水平,银川市室内氡所产生的居民年均有效剂量值为1.83 mSv,在公众年有效剂量安全范围内(5 mSv)。鉴于氡及其子体对人健康潜在危害大,建议应做好防氡措施。The indoor concentration has a significant impact on human health.In order to fully understand the level of indoor radon concentration and the effective dose of public radiation of Yinchuan(three districts and two counties).We use RAD7 to monitor the indoor radon concentration of 15 rooms in Yinchuan City(three districts and two counties)each month and analyze the data.The measurement results show that the indoor radon concentration of the Yinchuan(three districts and two counties)is between 3.04-144 Bq/m3 and the average calculation is 55.89 Bq/m3,which is higher than the world average.The effective dosage is 1.83 mSv,within the scope of effective dose safety of the public year(5 mSv).In view of the great potential harm to human health,preventive measures should be taken.
