In the present study, radiation shielding properties of two glassy composite materials that are widely used in electronics, photovoltaic applications, and sensor technology, were investigated in the photon energy range from 15 keV to 15 MeV. The materials chosen were (ITO)/VO/BO and ZnO/VO/BO including various concentrations of BO. Radiation interaction was simulated and shielding parameters calculated by means of the MCNP and BXCOM codes. More specifically, buildup factors, effective electron density ([Formula: see text]) and effective atomic number ([Formula: see text]) were calculated with BXCOM, while mass attenuation coefficients ([Formula: see text]), half-value layer (HVL) and tenth-value layer (TVL) values were calculated with MCNP. The results were compared with those obtained with the WinXCOM code, for validation. Acceptable and preferable results were obtained for both composites as alternative to other glassy shielding materials. The composite including ITO showed better shielding properties than the composite including ZnO. In terms of radiation shielding, both composites turned out to be better than concrete and close to lead.
在本研究中，研究了两种广泛应用于电子、光伏应用和传感器技术的玻璃状复合材料在光子能量范围为 15keV 至 15MeV 时的屏蔽性能。所选择的材料是（ITO）/VO/BO 和 ZnO/VO/BO，其中包含不同浓度的 BO。通过 MCNP 和 BXCOM 代码模拟了辐射相互作用并计算了屏蔽参数。更具体地说，使用 BXCOM 计算了积累因子、有效电子密度 ([Formula: see text]) 和有效原子数 ([Formula: see text])，而使用 MCNP 计算了质量衰减系数 ([Formula: see text])、半价层 (HVL) 和十分之一层 (TVL) 值。将结果与使用 WinXCOM 代码获得的结果进行了比较，以进行验证。两种复合材料都作为其他玻璃状屏蔽材料的替代品获得了可接受和更优的结果。包含 ITO 的复合材料表现出比包含 ZnO 的复合材料更好的屏蔽性能。在辐射屏蔽方面，这两种复合材料都比混凝土好，接近铅。
