| 摘 要： | 基于中子活化分析（NAA），建立一种简便可靠的129I嬗变率测量方法。采用127I制作模拟靶件，利用1个参比靶件与两个嬗变模拟靶件同时照射，测量128I特征γ射线强度之比，并根据比值计算嬗变率。实验结果验证了方法的可行性，为129I的高注量率反应堆嬗变率测定提供了技术支持。

| Abstract: | Based on neutron activation analysis(NAA) technology,a reliable and convenient method was developed for 129I transmutation ratio measurement.Simulative targets of natural 127I were designed to examine the feasibility of the method.One reference target and two transmutation targets of 127I(simulating targets before and after transmutation,respectively) were irradiated together on a NAA device.According to the intensity ratio of gamma ray emitted by 128I in the transmutation targets and the reference,transmut... |
