The noted Design of a new and effective radiation shielding material is a growing demand to reduce the harmful effects of ionizing radiation in medical and nuclear applications. In this research article, three silver nitrate (AgNO₃) doped PVA polymers were reported to serve as potential shielding materials against gamma ray. These polymers were tested in terms of their polarizability, optical transmission, and metallization properties. Furthermore, the radiation shielding performance of the involved polymers was assessed by Geant4 simulations based on Monte Carlo approach over a large range of energies up to 15 MeV. The results indicate that the density of the present polymers increased from 1.19 g/cm³ for pure-PVA to 1.41 g/cm³ for 5% AgNO₃ doped PVA sample. At high energies, exceeding 150 keV, LAC values of all investigated samples become almost independent of their chemical composition. For Pure-PVA polymer, the LAC values start from its highest values of 1.358 cm⁻¹ at 15 keV then decrease with increasing energy to be 0.022 cm⁻¹ at 15 MeV. At all penetration depths and energies, EABF values were higher for Pure-PVA than those of other polymers. The AgNO₃ addition has a positive impact to improve the shielding performance of the polymer to be close to that of ordinary concrete (standard radiation shield).

一种新的有效辐射屏蔽材料的著名设计是减少医疗和核应用中电离辐射有害影响的日益增长的需求。在这篇研究文章中，报道了三种硝酸银 (AgNO ₃ ) 掺杂的 PVA 聚合物可作为潜在的伽马射线屏蔽材料。对这些聚合物的极化率、光传输和金属化性能进行了测试。此外，所涉及聚合物的辐射屏蔽性能通过基于蒙特卡罗方法的 Geant4 模拟在高达 15 MeV 的大范围能量下进行评估。结果表明，本发明的聚合物的密度1.19克/厘米增加³为纯PVA 1.41克/厘米³为5％的AgNO ₃掺杂的 PVA 样品。在超过 150 keV 的高能量下，所有研究样品的 LAC 值几乎与其化学成分无关。对于纯 PVA 聚合物，LAC 值在 15 keV 时从其最高值 1.358 cm ^{-1 开始}，然后随着能量的增加而降低，在 15 MeV 时降至 0.022 cm ^-1。在所有穿透深度和能量下，纯 PVA 的 EABF 值都高于其他聚合物。添加AgNO ₃对提高聚合物的屏蔽性能接近普通混凝土（标准辐射屏蔽）具有积极影响。
