摘要
综述了核保障活动中通用的富集度仪原理分析法、多组铀分析法(MGAU)和多效固定能响应函数分析法(FRAM)等测量铀富集度的γ能谱法进行对比分析,确定三种方法的适用测量范围及样品富集度、均匀性、几何形状和容器等因素对三种方法测量性能的影响。
In this paper,the principle analysis of enrichment meter,multi group uranium analysis method and fixed energy,response function analysis with multiple,which are commonly used in nuclear support activities,are compared.The applicable measurement range of the three methods and the influence of sample enrichment,uniformity,shape and container on the measurement performance of the three methods are determined.
