α径迹蚀刻测量是核技术找水中的一种方法。α径迹,就是当α射线穿过胶片时留下的痕迹;蚀刻,就是用化学试剂除去胶片表面薄膜,显示径迹的化学处理过程。用α径迹蚀刻测量放射性强度差异,可以找出含水的断裂构造,达到间接寻找基岩裂隙水的目的。它是将一小片胶片用透明胶布固定 Alpha Track Etch measurements are a way for nuclear techniques to find water. The alpha track, which is the trace of alpha rays passing through the film, is the chemical treatment that removes the film on the surface of the film with a chemical reagent and shows the track. Using a-track etch to measure radioactive intensity differences, it is possible to find water-bearing fracture structures and to indirectly look for bedrock fissure water. It is a small piece of film with a transparent tape fixed
