This paper has been focused on the a detail study on non-ionizing and ionizing electromagnetic (EM) shielding features and build-up factors of reinforced with ferrochrome (FeCr) composites. The non-inozing electromagnetic shielding performance quantities of composites have been determined in the frequency range between 12.4 and 18.0 GHz. Also, the experimental mass attenuation coefficients (MAC) have been estimated using gamma spectrometer and various radioactive point, and compared to those of theoretical and simulation (MCNPX) results. With help of the obtained linear attenuation coefficients, several attenuation quantities, i.e., effective atomic number (Z_eff), half value layer (HVL), and mean free path (MFP) have been discussed. In addition, buildup factors (EBF and EABF) values have been estimated utilizing the G-P fitting method. The results showed that composite encoded FeCr(15%) is superior shielding attenuation properties among the investigated samples.

本文集中于对非电离和电离电磁（EM）屏蔽特性以及铬铁（FeCr）复合材料增强材料的堆积因子的详细研究。已在12.4至18.0 GHz的频率范围内确定了复合材料的非粘合电磁屏蔽性能量。此外，已使用伽马能谱仪和各种放射性点估算了实验质量衰减系数（MAC），并将其与理论和模拟结果（MCNPX）进行了比较。借助获得的线性衰减系数，可以得到几个衰减量，即有效原子序数（Z _eff），半值层（HVL）和平均自由路径（MFP）进行了讨论。此外，已经使用GP拟合方法估算了堆积因子（EBF和EABF）值。结果表明，复合编码的FeCr（15％）在研究样品中具有优异的屏蔽衰减性能。
