基于MC方法的n-γ混合场复合屏蔽研究

Multiple Shielding Study of n-γ Mixed Field Based on MC Way

利用MCNP程序,研究了n-γ混合场的自身特性及屏蔽层的排列方式对复合屏蔽的影响。结果表明,混合场中中子与γ的能量与注量比,以及屏蔽体结构,对复合屏蔽的效果有较大影响;在屏蔽体设计过程中予以充分的考虑,有利于屏蔽体的小型化与轻型化。

The impact on multiple shielding from Self - characteristics of n -γ mixed field and tactic way of shielding floor is studied by dint of the MCNP. The result shows that： the energy and flux ratio of neutron and together with the structure of shielding floor have a great impact on multiple shielding. It will be propitious to the miniaturization and light - weight trend of the shielding body, if those terms are fully considered.
