摘要
提出了在CR-39SSNTD受照面加一定厚度的吸收体甄别掉氡,从而实现直接被动积分测量水平的方法。这种甄别掉氡的方法会降低测灵敏度,但通过在采样小室加静电场的方法可以将测灵敏度大大提高。
A method of discriminating radon from thoron by using an absorber has beendeveloped. This discriminating method realizes direct passive and integrating thoronmonitoring, but reduces thoron measurement sensitivity. By means of usingelectrostatic collection inside the sampling chamber, the sentivity can be increasedlargely.
