摘　　要：采用γ能谱法和PC/FRAM软件分析检测铀样品中235U的富集度。实验结果表明,随机抽样的2个铀样品中,235U富集度测定值与标称值间相对偏差均在3%以内。该方法可用于铀样品中235U富集度的测量,并为今后核材料的测量提供一定的参考。235U enrichment in uranium samples were measured and verified using the γ-spectrometry and special PC/FRAM code.Different plots on two uranium targets were measured,which was selected randomly.The results show that the relative deviation between measured 235U enrichment and declared value is less than 3%,thus it can be concluded that γ-spectrometry is efficient in verifying 235U enrichment in uranium samples.This method could provide some references for measurement of nuclear material.
