近年来的一个特点是,人们应用射气法普查放射性原料的兴趣越来越浓。部分原因是,在普查工作中应用射气径迹法和电子α仪测量技术等“曝光”法测量氡浓度,由气体取样和壤中氡浓度随时间的变化给测量结果带来的误差,低于经典的爱曼仪射气测量的误差。应用前两种方法已经不止一次地发现了埋深数十米、乃至100—150米的铀矿体。射气法的这一探测深
One of the characteristics of recent years is that people are more and more interested in applying radiometry to census radiological raw materials. Part of the reason is that the radon concentration was measured by “exposure” method such as the gas track method and the electronic alpha meter measurement technique in the census work. The error caused by the sampling of the gas and the change of radon concentration in the soil with time was low Errors in the measurement of classic Aman instruments. The first two methods have been used to find uranium ore bodies buried in tens of meters and even 100-150 meters on more than one occasion. The gas law of this deep exploration
