摘要
介绍了2005～2007年用DHZM-I型氡及其子体连续监测仪对某矿山的工作场所和生活区分别进行环境氡及其子体浓度的测量。监测结果表明,所监测的工作场所中,大部分监测点的氡及其子体浓度都在国家规定的限值范围内;在居民区,扣除本底后,未发现任何监测点的个人有效剂量当量超过国家规定的限值。笔者还对该矿山的平衡因子进行了分析研究,并给出了研究结果。
From 2005 to 2007, the environmental concentration of radon and its daughters in a mine, including workplace and residential areas is measured respectively by using DHZM-Ⅰ radon and its daughters continuous monitor. The surveyed data show that radon and its daughters concentration in most monitoring points is lower than the limited safety value of the national regulation in the monitoring workplaces, no monitoring point in the residential area is discovered to have individual effective dose equivalent more than the safety limited value of national stipulation after deducting the background value. The authors also analyze the equilibrium factor of the mine and make discussion on the results.
