摘　　要：为标识和鉴别核材料,提高核材料的安全管理能力,研究建立了核材料自发辐射γ特征谱的特征信息及提取方法,以及模板匹配算法,提出了核材料γ辐射模板识别技术和方法。对不同贮存状态、不同类别核材料,运用MC方法模拟研究了其γ辐射特征,并结合相关实验,验证了γ辐射模板识别方法的有效性。In this paper, in order to label and identify nuclear materials and improve abilities of the security management of nuclear materials, the feature of γ-ray characteristic spectrum of nuclear materials and the template matching algorithm are studied, and a γ-ray template-identifying method for nuclear materials is presented. An MC code is used to simulate the γ-ray characteristic for different categories of nuclear materials in different storage conditions, and the γ-ray template identification method has been validated by measurements with an HPGe system.
