摘要
采用活性炭吸附闪烁法测定了湛江市部分住房室内、外空气中的平衡当量氡浓度。结果表明 ,住房室内、外空气中平衡当量氡浓度平均值分别为 2 5 2 7Bq/m3 和 14 6 8Bq/m3 ,室内空气中平衡当量氡浓度显著高于室外 (P <0 0 1) ;不同装饰材料的住房室内空气中平衡当量氡浓度各有差异 ,其中以花岗岩为装饰材料的住房室内平衡当量氡浓度 (31 18Bq/m3 )为最高 ,水泥地板住房 (14 71Bq/m3 )
The indoor and outdoor radon concentration of some buildings in Zhanjiang city was measured with liquid scintillation by activated carbon accumulation method. The results showed that the averages of indoor and outdoor radon concentration were 25 27Bq/m 3 and 14 68Bq/m 3 respectively. The indoor radon concentration was significantly higher than that of outdoor(P<0 01). The indoor radon concentrations of buildings showed different result between different decorating materials. The indoor radon concentration of buildings which decorated with granite was the highest(31 18Bq/m 3), and it was the lowest that of cement floor buildings(14 71Bq/m 3).
