α经迹找矿法七十年代初,国外在射气测量的基础上,进一步开展了α经迹找矿方法。这一方法和射气测量方法相比,灵敏度高,抗干扰能力强,勘探深度加大了几倍至十几倍。我国铀矿地质部门已广泛运用了α经迹找矿方法。在铀矿地质工作中,它大有取代氡射气测量方法的趋势。多年来的工作实践证实,找铀矿的大多数物化探方法,都可以用来找磷块 α Tracing Find Method In the early seventies, based on the radiometric measurement abroad, the method of ore deposit prospecting for α was further developed. Compared with the method of radiometric measurement, this method has high sensitivity and strong anti-interference ability, and the depth of exploration has increased several times to ten times. China’s uranium geology department has been widely used a deposit via prospecting methods. In uranium geological work, it has greatly replaced radon gas measurement methods. Work practice over the years has confirmed that the majority of geophysical and geochemical exploration methods for uranium can be used to find phosphorous
