This paper evaluated the radiation shielding features of different 19 alloy samples utilizing the EPICS2017 library for cross section interpolation. The alloys include the ternary Fe, Cr, and Ni based alloys, nickel silver alloys, ternary Cu, Zn, Pb based alloys, and four binary Ag/Cu, Ag/Cu, Pd/Cr and Pd/Cu based alloys. Comparative results were provided by the XCOM and several experimental and Monte Carlo based values in literature. All results described a decreasing trend of mass attenuation coefficient with increasing photon energy. A good agreement was obtained among EPICS2017, MCNPX and experiments. The strongest agreement was obtained between EPICS2017 and XCOM with relative differences between 0.00 and 0.36%. The obtained results highlight the capability of EPICS2017 as a new and accurate theoretical method for future radiation shielding research and development of alloys.

本文利用EPICS2017库进行截面插值评估了19种不同合金样品的辐射屏蔽特性。合金包括三元铁，铬和镍基合金，镍银合金，三元铜，锌，铅基合金，以及四种二元银/铜，银/铜，钯/铬和钯/铜基合金。XCOM提供了比较结果，并提供了一些基于实验和基于蒙特卡洛的值。所有结果都描述了质量衰减系数随光子能量的增加而下降的趋势。EPICS2017，MCNPX和实验之间获得了良好的协议。EPICS2017与XCOM之间获得了最强烈的协议，相对差异在0.00到0.36％之间。
