摘要

用Monte Carlo粒子输运计算程序（M-C程序）对入射能量从0.025eV到20MeV的中子及入射厚度1–40cm的多种材料进行了中子透射性能计算。这些屏蔽材料有主体材料聚乙烯、水和混凝土、铁、铜

铅和聚乙烯-碳化硼复合材料

以及功能添加剂碳化硼和氧化钆。结果显示

随着材料厚度的增加

中子透射系数降低;同一种材料

随入射中子能量的降低透射系数降低的幅度呈增大趋势

但聚乙烯和水的透射系数较小且下降幅度与能量低于0.1MeV的中子基本相同

有些材料随厚度增加出现能量较高中子的透射系数低于能量较低中子透射系数的现象;不同材料的中子透射系数随厚度增加而降低的幅度在能量较低时差别明显

能量高时差别减小。主体材料与功能添加剂组合有利于提高材料的屏蔽能力。

Abstract

In this paper

the MCNP code is used to calculate neutron transmission through various materials of 1–40 cm thickness in energy range of 0.025 eV to 20 MeV.The materials are principal shielding materials of PE

water

concrete

Pb and PE/BC4composite

and the additives of B4C and Gd2O3.The following results were obtained:(1) the neutron transmission decreased with increasing thicknesses of a material;(2) for a certain material

with decreasing energy of the neutrons

the neutron transmission decreased faster

except PE and water

where the neutron transmision keeps almost the same in the entire energy range;and(3) for low energy neutrons

the differences of transmission decreasing trend with the increasing thicknesses for different materials were significant

whereas for high energy neutron

the decreasing trend was not distinct.A combination of a main material with an additives can achieve better shielding effect.
