摘要
调查了长沙市某建筑住宅室内全天氡浓度变化情况,研究了室内温度、湿度对氡浓度的变化影响,结果显示住宅室内空气氡浓度均值为55.8 Bq/m3。室内氡浓度变化呈现夜间高白天低的规律,温度对室内氡浓度基本呈现负相关影响,湿度对室内氡浓度呈现正相关影响。估算了氡及其子体对室内居住人员的有效剂量,室内氡及其子体对居住人员产生的年有效剂量为1.57 mSv,提出氡的防治、监管措施与建议。
The indoor radon concentration of a building in Changsha was investigated.And the effect of indoor temperature and humidi-ty on the change of radon conce ntration was studied.The results showed that the average indoor radon concentration was 55.8 Bq/m3.The variation of indoor radon concentration is high at night and low dur ing the day.Temperature has a negative correlation with indoor radon concentration,and humidity has a positive correlation with indoor radon concentration.The effective dose of radon and its daughter in indoor residents is estimat-ed,and the annual effective dose of radon and its progeny on indoor residents is 1.57 mSv.The measures and suggestions of radon prevention and supervision are put forward.
