【民德《同位素实践》1990年第1期第37页报道】为了考虑因不同类型中子相互作用而在介质中引起的次级辐射效应,对快中子通过某些介质的迁移进行研究是必要的。最重要的相互作用是产生γ辐射的相互作用:(n,γ),(n,n,γ),(n,p,γ),(n,α,γ)……。必须准确地确定次级γ辐射的产额和 1990, No. 1, p. 37]. In order to consider the secondary radiation effects caused by different types of neutrons in the medium, the study on the migration of fast neutrons through certain media necessary. The most important interaction is the generation of gamma radiation interactions: (n, γ), (n, n, γ), (n, p, γ), (n, α, γ) The output of secondary gamma radiation must be accurately determined
