摘要
In this paper,the fundamental principle,field working method and relative technology requirement of Radon measurement are introduced.The test in Tucheng mine gap area and application in Heyang by RaA emanometer of type FD-3017A are taken as examples,it shows the application of RaA emanometer has good effect in the determination of gap area.This method has strong adaptability for the testing field,won’t be affected by geo-electrify and geo-magnetism,has deep determined depth and the method is simple,so it has widely application prospect.
