^(37)Ar用于视察地下核试验的尝试

Application of ^(37)Ar in the Verification of a Clandestine Nuclear Test

对地下核爆泄漏气体中放射性核素37Ar进行取样、提纯及测量 ,并研究了泄漏速率随时间和位置的变化规律。结果表明 :监测土壤中37Ar的含量可有效地核查地下核试验。

The techniques of collection, extraction and measurement of radionuclide 37 Ar in the gas venting from an underground nuclear explosion are described. The responses of venting rate as explosion time or distance are specifically studied. The research indicates that it is feasible to verify an underground nuclear test by monitoring 37 Ar sample from the underground soil.
