| 摘 要： | 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。

Multiple Shielding Study of n-γ Mixed Field Based on MC Way |
| |
| Abstract: | 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 γ 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. |
