This work aims to prepare modified glassy barriers of the composition (70 − x) mol% B₂O₃ + 20 mol% Na₂O + 10 mol% BaO + x mol% La₂O₃ for use as radiation shielding materials. The cooling method has been considered for the sample’s preparation process. The structural properties were investigated using density and Infrared Spectroscopy. The hardness of the prepared glasses was studied. The optical transmittance and absorbance of the prepared glasses was measured using optical spectra measurements. The prepared samples were exposed to a parallel beam of gamma rays emitted from different radioactive sources. Moreover, the shielding properties were evaluated experimentally and theoretically. The resulting value of the proposed programs is largely in line with the experimental values. The results prove that the studied glass has a largely shielding behavior for gamma rays by increasing lanthanum and vice versa for neutrons. In addition, it has been observed that the absorbance of glass samples and hardness values increase with increasing lanthanum content.

这项工作的目的是制备组成为 (70 − x) mol% B ₂ O ₃ + 20 mol% Na ₂ O + 10 mol 的改性玻璃屏障% BaO + x mol% La ₂ O ₃ 用作辐射屏蔽材料。样品制备过程考虑了冷却方法。使用密度和红外光谱研究结构特性。研究了所制备的玻璃的硬度。使用光谱测量来测量所制备的玻璃的光学透射率和吸光度。将制备的样品暴露于从不同放射源发射的平行伽马射线束中。此外，还通过实验和理论评估了屏蔽性能。所提出的方案的结果值在很大程度上与实验值一致。结果证明，所研究的玻璃通过增加镧对伽马射线具有很大的屏蔽行为，反之亦然对中子具有屏蔽行为。此外，还观察到玻璃样品的吸光度和硬度值随着镧含量的增加而增加。
