摘　　要：目的 对十堰市城区居民室内氡浓度进行监测,分析居民室内氡浓度水平及影响因素。方法 从2019年4月到7月,采用RSKS标准型探测器对十堰市城区共计125户居民室内氡浓度进行测量并分析。结果 2019年所监测的十堰城区居民室内氡浓度结果呈偏态分布,范围为13.8~145 Bq/m^(3),M(P_(25),P_(75))为38.3(29.0,62.0) Bq/m^(3),居民因吸入氡及其子体产生的年均有效剂量估算值为0.52~5.50 mSv,M(P_(25),P_(75))为1.45(1.10,2.36) mSv,与相关文献一致;不同建筑结构(H=14.10,P<0.001)、楼层(H=24.41,P<0.001)和地区(H=8.963,P<0.05)均是居民室内氡浓度水平的影响因素,且差异均有统计学意义。结论 十堰市城区居民室内氡浓度小于国家标准限值,但在日常生活中还是需要注意采取合适的方法,尽量降低家中氡浓度。Objective To monitor the indoor radon concentration of urban residents in Shiyan,China,and to analyze the related influencing factors.Methods From April to July,2019,RSKS standard detectors were used to measure the indoor radon concentration of 125 households in Shiyan,and the results were analyzed.Results The indoor radon concentration of residents in Shiyan showed a skewed distribution,ranging from 13.8 to 145 Bq/m^(3),and M (P_(25),P_(75)) was 38.3 (29.0,62.0) Bq/m^(3).The estimated annual effective dose of radon and radon daughters from inhalation was 0.52-5.50 mSv,and M(P_(25),P_(75)) was 1.45 (1.10,2.36) mSv,which was consistent with literature.Building structure (H=14.10,P0.001),floor(H=24.41,P0.001),and geographical region (H=8.963,P0.05) were influencing factors of indoor radon concentration,and the differences were significant.Conclusion The indoor radon concentration of urban residents in Shiyan is lower than the national standard limit.However,in daily life,it is still necessary to take appropriate measures to reduce the concentration of indoor radon as much as possible.
