【摘要】 阐述了采用主动法探测炸药的原理,综合分析屏蔽体、自然界本底和反应截面对炸药中1H、12C、16O和14N核素的测量影响。并利用252Cf中子源辐照模拟炸药半球,采用高纯锗γ探测器探测了由中子与1H、12C、16O和14N核素发生(n,γ)俘获反应产生的γ射线。通过实验研究了主动法探测炸药的可行性,分析了探测1H、12C、16O和14N四种核素的瞬发γ射线的优缺点。更多还原

【Abstract】 In this paper, the principal and techniques of activity interrogating the explosives have been illuminated. Some factors affecting the results have been analyzed. We adopted high pure germanium γ-detector to measure γ-ray from the simulated dynamite irradiated by 252Cf neutron source. The feasibility of the method was and analyzed and advantages and shortages of detecting 1H, 12C, 16O and 14N were discussed.更多还原
