摘要
介绍了2005～2008年期间,用REM-III型氡析出率仪和DHZM-I型氡及其子体连续监测仪对某铀矿山的工作场所和居民区分别进行土壤(岩石)氡析出率和环境空气中氡浓度的测量,并应用适当的估算模式估算氡吸入所致公众年有效剂量。结果表明,随着对辐射环境治理工作的加强和人们环保意识的提高,在所监测的工作场所中,大部分监测点的氡浓度没有超过国家规定的限值;在居民区,也没有发现任何监测点的个人剂量超过核工业辐射环境质量评价规定的限值。
From 2005 to 2008, the environmental concentration of radon exhalation rate in soil (rocks) and radon density in air of a mine, including workplace and inhabited area respectively has been measured with REM-Ⅲ radon exhalation rate monitor and DHZM-I radon and its daughters continuous monitor. Suitable estimating pattern is used to estimate public annual effective dosage of radon. The surveyed data show that radon concentration at most monitoring points in the monitoring workplaces is lower than the limited ...
