In this research article, the radiation shielding properties of newly developed high Fe content amorphous alloys were reported. The chemical compositions of these alloys were Fe₈₃B₉C₃Si₄P₁, Fe₈₄B₁₀C₂Si₂P, Fe₈₅B₈C₃Si₃P₁, and Fe₈₆B₅C₈P₁. Monte Carlo simulation method was successfully used to study the problem of radiation propagation through theses alloys under suitable boundary conditions of vacuum. Our results indicate that MAC value decays as photon energy grows varying from 0.0997 to 0.0387, 0.0997–0.0387, 0.0998–0.0387, and 0.0998–0.0387 cm²/g for FBCSP1, FBCSP2, FBCSP3, and FBCSP4 respectively. However, gradual increase was observed in both parameters of mean free path (MFP) and half value layer (HVL) as energy increases. The maximum and minimum value of the effective atomic number (Z_eff) was 23.09 and 22.97, 23.29 and 23.17, 23.41 and 23.30, and 23.4 and 23.29 for FBCSP1– FBCSP4 respectively. FNRC (Fast Neutron Removal Cross-section) values were: 0.1538, 0.1538, 0.1536, and 0.1561cm-1 for FBCSP1– FBCSP4 respectively. Moreover, an extensive comparison was reported between the radiation shielding proficiency of the studied alloys and that of the traditional materials. It can be concluded that, FBCSP alloys can conveniently replace the traditional materials in photon shielding application especially when space is a constraint.

在这篇研究文章中，报道了新开发的高铁含量非晶合金的辐射屏蔽性能。这些合金的化学成分为Fe ₈₃ B ₉ C ₃ Si ₄ P ₁，Fe ₈₄ B ₁₀ C ₂ Si ₂ P，Fe ₈₅ B ₈ C ₃ Si ₃ P ₁和Fe ₈₆ B ₅ C ₈ P _1。。蒙特卡罗模拟方法已成功用于研究在合适的真空边界条件下通过这些合金的辐射传播问题。我们的结果表明，对于FBCSP1，FBCSP2，FBCSP3和FBCSP4 ，MAC值随着光子能量的增长而衰减，从0.0997到0.0387、0.0997-0.0387、0.0998-0.0387和0.0998-0.0387 cm ² / g。但是，随着能量的增加，在平均自由程（MFP）和半值层（HVL）的两个参数中都观察到了逐渐增加的趋势。有效原子序数的最大值和最小值（Z _eff）分别为FBCSP1-FBCSP4的23.09和22.97、23.29和23.17、23.41和23.30，以及23.4和23.29。FBCSP1-FBCSP4的FNRC（快速中子去除截面）值分别为：0.1538、0.1538、0.1536和0.1561cm-1。此外，据报道，在所研究的合金与传统材料的辐射屏蔽能力之间进行了广泛的比较。可以得出结论，FBCSP合金可以在光子屏蔽应用中方便地替代传统材料，特别是在空间受限的情况下。
