In this study, the radiation shielding effectiveness of iron phosphate glass (FeO–PO) doped with antimony (Sb) and tellurium (Te) is assessed in detail using advanced computational methods. The projected range, mass stopping power, and KERMA (Kinetic Energy Released per unit MAss) for fourteen different iron phosphate glass samples are calculated through the PAGEX and SRIM software. Mass attenuation coefficients, linear attenuation coefficients, mean free path, half value layers, tenth value layers, and effective atomic number are determined in 0.015–15 MeV energy range. The research reveals that doping iron phosphate glass with SbO significantly enhances its shielding capabilities when compared to the inclusion of TeO. Another important aspect is, the IPGSb50 sample exhibited the highest KERMA values, indicating its exceptional capacity for energy absorption from ionizing radiation. Additionally, the IPGSb50 sample exhibited the lowest projected range for alpha particles, also this sample demonstrated a similar prowess in limiting the penetration of proton particles. Our findings indicate that the incorporation of SbO and TeO into iron phosphate glass matrices results in a noticeable improvement in gamma radiation shielding effectiveness. These doped glasses could serve as potent alternatives to traditional lead-based shielding materials, offering a safer and potentially more effective barrier against a variety of radiation types.

KERMA，锑和碲增强磷酸铁玻璃的投影范围、质量阻止本领和伽马射线屏蔽性能

在这项研究中，使用先进的计算方法详细评估了掺杂锑（Sb）和碲（Te）的磷酸铁玻璃（FeO-PO）的辐射屏蔽效能。通过 PAGEX 和 SRIM 软件计算 14 种不同磷酸铁玻璃样品的预计射程、质量阻止本领和 KERMA（每单位 MAss 释放的动能）。质量衰减系数、线性衰减系数、平均自由程、半值层、十值层和有效原子序数在0.015-15 MeV能量范围内确定。研究表明，与掺有 TeO 相比，掺有 SbO 的磷酸铁玻璃可显着增强其屏蔽能力。另一个重要方面是，IPGSb50 样品表现出最高的 KERMA 值，表明其吸收电离辐射能量的卓越能力。此外，IPGSb50 样品表现出 α 粒子的最低预计射程，该样品在限制质子粒子穿透方面也表现出类似的能力。我们的研究结果表明，将 SbO 和 TeO 掺入磷酸铁玻璃基质中可显着提高伽马辐射屏蔽效果。这些掺杂玻璃可以作为传统铅基屏蔽材料的有效替代品，为各种辐射类型提供更安全且可能更有效的屏障。
