近年来,世界各地的恐怖活动极为频繁,给世界各国人民的生命财产造成极大的威胁。液体爆炸物由于其形态的多样性,包装容器不一定是金属,导致检查更加困难。液体爆炸物中含有的C、N、H、O等元素的含量和比例各不相同,不同于其他非爆炸物,这就为检测它们提供了依据。快中子法检测液体爆炸物的方法是通过测量14 MeV中子与各元素核反应中的非弹性散射(n,n’,γ)释放的特征γ射线区分是否为爆炸
In recent years, the terrorist activities around the world have been extremely frequent, posing a tremendous threat to the lives and property of the people of all countries in the world. Liquid explosives Due to their diversity of forms, the packaging container need not be metal, which makes inspection more difficult. Liquid explosives contain C, N, H, O and other elements of the content and the proportion of different, unlike other non-explosive, which provides a basis for testing them. Fast neutron detection of liquid explosives by measuring 14 MeV neutron and each element of the nuclear reaction of inelastic scattering (n, n ’, γ) release characteristics of gamma rays distinguish whether the explosion
