用于监测是否遵守核不扩散条约的核保障系统很大程度上依靠对环境样品的分析,未申报的核活动可通过检测周围环境样品中铀和钚的同位素丰度比来进行监测。在该应用中在总铀含量在ng量级的样品中铀的系列同位素(234U、235U、236U、238U)能被测量是有必要的。为满足这方面的应
The nuclear safeguards system used to monitor compliance with the NPT relies heavily on the analysis of environmental samples, and undeclared nuclear activity can be monitored by measuring the abundance ratio of isotopes of uranium and plutonium in ambient samples. It is necessary in this application to measure uranium isotopes (234U, 235U, 236U, 238U) in samples of total uranium content in the order of ng. To meet this should be
