The current study explores the effect of BaO content on the shielding, optical, structural, and physical features of 10TiO2–10SiO2-(80-x)B2O3-xBaO (10 ≤ x ≤ 30) glass samples for their ability to be used as radiation shielding substances. X-ray diffraction spectra affirmed the amorphous state for all prepared samples. A series of physical parameters confirm the stability of the prepared glasses. The optical properties confirm the forming of non-bridging oxygens and these results are in line with the physical and structural properties and FTIR results. Regarding the shielding properties, the mass attenuation coefficient was measured experimentally and compared with the compatible values obtained from the XCOM program. Furthermore, other photon shielding properties, such as radiation protection efficiency, mean free path, exposure buildup factor, and energy absorption buildup factor, were calculated within the energy range of 15 keV-15 MeV. It was determined that this glass composition is suitable for photon radiation shielding applications.

一系列硼硅酸盐玻璃的辐射屏蔽,结构,物理和光学特性

目前的研究探讨了BaO含量的在屏蔽的效果,光学,结构和物理特征10TiO 2 -10SiO 2 - (80-x)B 2 ö 3 -xBaO(10≤  X ≤30)玻璃样品用作辐射屏蔽物质的能力。X射线衍射光谱确认了所有制备样品的非晶态。一系列物理参数证实了所制备玻璃的稳定性。光学性质证实了非桥连氧的形成,并且这些结果与物理和结构性质以及FTIR结果一致。关于屏蔽性能,通过实验测量质量衰减系数,并将其与从XCOM程序获得的兼容值进行比较。此外,在15 keV-15 MeV的能量范围内,还计算了其他光子屏蔽特性,例如辐射防护效率,平均自由程,曝光累积因子和能量吸收累积因子。
