全面禁止核试验条约的达成是防止核武器扩散的重要手段. 如何判断一次核试验的发生是一个关键课题. 研究了基于测量惰性气体氙同位素133mXe，133Xe，135Xe和131mXe来鉴别核试验和民用反应堆泄漏的方法. 通过分析这些处于复杂衰变链上核素的数量随时间的变化，寻找核试验与反应堆泄露事件的区别. 对两次朝鲜可疑的事件进行了测量和分析. 为了验证理论计算结果，设计了一次热中子辐照钚的模拟实验.

It is an important approach to preventing nuclear proliferation that comprehensive nuclear test ban treaty is reached. How to judge whether a nuclear test has happened is a key point. In this paper we investigate a method to distinguish between a nuclear test and leakage from civilian nuclear reactor by measuring inert gas xenon nuclides 133mXe, 133Xe, 135Xe, and 131mXe. The distinction between the nuclear test and the reactor leakage is found by analyzing the variation of nuclide quantity with time in a complex decay chain. Two suspicious events in North Korea are measured and analyzed. In order to verify the theoretical results, an experiment of imitating plutonium irradiated by thermal neutron is designed.-
