| 摘 要： | 2018—2019年，通过对深圳市室内布设的240个氡浓度监测点进行监测、数据统计、检验、分析比对后，得出深圳市室内氡浓度水平分布规律和变化趋势。根据《室内氡及其衰变产物测量规范》对各监测点位制定测量方案，采用连续测氡仪进行氡测量。分析研究得出，目前深圳市室内平均氡浓度值为（63±10） Bq/m3，其中平均氡浓度值最高为盐田区和光明新区（76±22） Bq/m3，最低为龙华新区（53±12） Bq/m3。目前深圳地区室内氡浓度比20世纪90年代升高了1.4倍，丰水期和枯水期室内氡浓度变化不显著，调查中全是已建建筑，没有发现室内氡浓度超过国标规定的氡浓度限值的建筑。

| Abstract: | Objective 2018—2019 year，through monitoring，data statistics，testing，analysis and comparison of 240 monitoring points of indoor radon concentration in Shenzhen City，the distribution law and change trend of indoor radon concentration level in Shenzhen were obtained.Methods according to "specifications for monitoring of indoor radon and its decay products" to formulate the measurement scheme for each monitoring point.Radon measurement was carried out by continuous radon meter.Results showed that，at present，the average indoor radon concentration value in Shenzhen is （63±10） Bq/m3，among which the highest value is （76±22） Bq/m3 in Yantian District and Guangming New District，and the lowest value is （53±12） Bq/m3 in Longhua New District.At present，the indoor radon concentration in Shenzhen has increased by 1.4 times compared with that in the 1990s.There is no significant change in the indoor radon concentration during the wet season and the dry season.All the existing buildings in the survey have not been found that the indoor radon concentration exceeds the limit set by the national standard. |
