- 摘 要:为研制兼具质地轻、体积小、耐高温等特点的新型中子、γ混合辐射屏蔽材料，用遗传算法建立了屏蔽材料优化设计方法。对应用该方法设计出的3种材料进行MCNP软件检验，并与铁等材料进行比较。结果表明：在达到一定厚度后，这些材料对裂变中子、γ的总屏蔽效果均超过铁，且相同屏蔽效果下的铁质量当量显著下降。

Abstract : Optimized in lightweight , compact ness and high temperat ure sustaining t he
shielding material s for neut ron and gamma radiation were designed based on genetic
algorithms. Three kinds of material s studied by this met hod were designed and
simulated wit h MCNP code , and result s were compared wit h those f rom iron etc. The total shielding effect s of the materials with certain thickness for fission neutron and γ -rays are all much better than iron , and the equivalent masses are lower than iron at same shielding effect .
Key words : radiation shielding material ; genetic algorithms ; neutron ;γ 2ray ; MCNP code
