摘要
通过对核弹头部件中核材料自发衰变γ射线输运过程的分析，根据不同类型的核弹头有不同的出壳γ射线能谱形状，研究泄漏γ射线特征能谱作为核弹头指纹的可行性。还通过对高能和低能γ射线穿透谱的比较，分析球壳的厚度。
The γ ray transport process in some pits of warhead models has been studied.Since the penetrating γ ray spectra are different for different models,the feasibility of using the γ ray from fissile materials as the fingerprint of the warhead has been analyzed.By comparing the characteristics of γ ray′s intensities,the thickness of bare ball of Wg.Pu can be estimated if its thickness is less than 1 5 cm.
