Abstract

In this paper

in order to label and identify nuclear materials and improve abilities of the security management of nuclear materials

the feature ofγ-ray characteristic spectrum of nuclear materials and the template matching algorithm are studied

and aγ-ray template-identifying method for nuclear materials is presented.An MC code is used to simulate theγ-ray characteristic for different categories of nuclear materials in different storage conditions

and theγ-ray template identification method has been validated by measurements with an HPGe system.
