利用γ射线法找水,是近年发展起来的一项新技术,各地在使用中出现了不少问题。本文针对存在的问题介绍了该方法在几种主要地层中的找水效果及能解决的地质问题。提出了在山高、坡陡、地下水位埋深较大的山丘地区找水,应以寻找低值异常为主的观点,并分析了形成低值异常的基本原因。 The use of gamma ray to find water, is a new technology developed in recent years, there have been many problems in use. In this paper, according to the existing problems, the water-seeking effect of the method in several major strata and the geological problems that can be solved are introduced. This paper puts forward the idea of ​​looking for water with low value anomaly in the hills with high mountain and steep slopes and deep groundwater table, and analyzes the basic reason for the formation of low anomaly.
