采用固体径迹法对中国辐射防护研究院室内外氡水平进行了调查,并估算了室内外氡子体及外照射所致成年人有效剂量。结果表明,室内外氡浓度平均值分别为33.6Bq/m~(-3)及13.7Bqm~(-3),平衡因子F值分别为0.4及0.54,室内外氡子体照射所致成年人平均年有效剂量分别为0.93mSv及0.19mSv,γ外照射致年有效剂量分别为0.55及0.08mSv,总年有效剂量1.75mSv。
Solid trace method was used to investigate the indoor and outdoor radon levels of China Radiation Protection Research Institute and the effective doses of radon in vitro and in vivo caused by external radiation were estimated. The results showed that the average indoor and outdoor radon concentrations were 33.6Bq / m -3 and 13.7Bqm -3 respectively, and the equilibrium F values were 0.4 and 0.54 respectively. The average adult radon exposure to indoor and outdoor adults The annual effective doses were 0.93mSv and 0.19mSv, respectively, and the annual effective doses of γ external irradiation were 0.55 and 0.08mSv, respectively. The annual effective dose was 1.75mSv.
