摘要
受到地下煤矿防止爆炸等因素限制,不能将测量氡仪器带入矿井。利用氧气袋在现场取样后进行测量,考虑到氧气袋自吸收、氡气渗透及扩散、衰变等因素影响,通过实验得出取样后测量不同时间的校正系数。
The radon instrument is not carried into underground coal mines because of in case of explosion. Con- sidering kinds of influence factors such as radon penetration and diffusion, self - absorption of oxygen bag, de- cay and so on, we get modification coefficient of different hours after we adopted oxygen bags to sample on site.
