摘要
对广西资源地区大气中氡的调查结果显示 ,该区室内、外大气中平均氡浓度分别为 10 1.0Bq/m3 和 10 4 .6Bq/m3 ,是世界平均值的 10倍和 2 .5倍 ;计算了氡子体所致的年有效剂量 ,由氡子体照射对成人和儿童所致年均有效剂量分别为 6 .2mSv/a和 9.2mSv/a,是世界平均值的 5倍。
This paper reports the results of radon investigation in Zhiyuan, Guangxi. The indoor and outdoor radon concentrations are 101.0 and 104.6 Bq/m 3,respectively, 10 and 2.5 times the average corresponding values of the world. Annual effective doses caused by the daughters of radon are 6.2 and 9.2 mSv/a for adults and children, respectively, about 5 times their average values in the world.
