基于中子活化分析的129I嬗变率测量方法实验研究
Experimental Research of Measurement Method of 129 I Transmutation Ratio Based on Neutron Activation Analysis
摘要
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, transmutation ratio was measured correctly. The results show that the NAA method developed in this work is feasible and convenient, and could be used for determining the transmutation ratio of 129I.关键词
