依靠一般地貌地质和电测法、地震法等物探手段,难以勘测呈不规则分布的脉状地下水。四川省原子核应用技术研究所在有关单位的大力支持和协助下,认真研究了有关天然放射性示踪技术应用机理和国内外成功、失败的经验,进行了大量科学实践,提出了具有我国特色的、能够在广大丘陵山区推广应用的γ找水法和γ找水仪的设计。γ找水仪是一般低能部分比较灵敏的γ射线探测仪器,成本低,重量轻,便于携带,可以单人徒步作业,使用方便。从钻成的600眼井的效果看,
Relying on geomorphologic geology and electrical geophysical methods, seismic methods and other geophysical methods, it is difficult to survey irregularly distributed vein-shaped groundwater. With the strong support and assistance of relevant units, Sichuan Institute of Nuclear Technology has seriously studied the application mechanism of natural radioactive tracing techniques and the successes and failures of domestic and foreign experiences, carried out a large amount of scientific practice, and put forward the proposal with characteristics of our country. In the vast hilly area to promote the application of γ find water law and γ water meter design. γ water detector is generally low-energy part of the more sensitive γ-ray detection equipment, low cost, light weight, easy to carry, you can single foot operation, easy to use. From drilling into the 600 wells look,
