摘　　要：提出了SF6示踪判定埋地放射性废水管道渗漏点方位的方法,并开展了初步工程验证试验。结果表明:SF6气体的横向扩散很少,绝大多数气体都在泄漏点的正上方释放,表明在废水管道上应用SF6示踪剂检漏并实现准确定位是可行的。The method of determining location of leakage of buried pipeline using SF6 tracing had been founded, and the engineering test for validation had been implemented. The research results showed that the majority of tracing gas had been released above the leakage point because of a little diffusing horizontally, which showed that locating the position of leakage point with SF6 tracing gas was feasible for the buried pipeline.
