一、前言目前国内外利用氡的子体寻找铀矿的测量方法有α卡法,活性碳吸附测氡法和~(218)Po 法等。各种方法在找矿过程中都显示了它的效果,并取得了一定的成功经验。但是,前两种方法都要两次上山,埋杯和取杯;后一种方法虽然取样方便,但尚需进行化学处理过程,因此限制了上述各法的工作效率。为弥补其不足,在这里向大家介绍一种新的测氡方法——~(218)Po法测氡。该法是利用取样片通过吸附的方法得到~(218)po,然后用α辐射仪测量它的α活度,达到测氡的目的。
I. INTRODUCTION At present, there are α-calorimetry, activated carbon adsorption-radon method and ~ (218) Po method for the uranium prospecting of progeny of radon at home and abroad. Various methods have shown its effectiveness in the prospecting process and have gained some successful experience. However, the first two methods have to go up the mountain twice, and the cup and the cup are taken. The latter method, although convenient for sampling, still needs to be subjected to the chemical treatment process, thus limiting the work efficiency of the above methods. To make up for its deficiencies, here to introduce a new method of measuring radon - ~ (218) Po method of measuring radon. This method uses the sample to get ~ (218) po by adsorption method, and then measure the α activity with α radiometer to achieve the purpose of measuring radon.
