The shielding of gamma radiation is of the utmost importance in industries, such as nuclear power plants, medical imaging, and space exploration. For the purpose of shielding objects in such an environment, it is essential to design materials with flexibility as well as high shielding capability. In order to enhance the radiation attenuation effectiveness of polymers, such as polyvinyl alcohol (PVA), glass has been blended with varying percentages. The fabricated composite has been subjected to gamma-ray interaction studies. The radiation shielding parameter, such as mass attenuation coefficient (μ/ρ), has been determined for various energies, such as 137Cs (661.6 keV) and 60Co (1173 and 1332 keV). It is observed that the PVA composite with glass exhibits improved gamma radiation shielding properties compared to PVA. Therefore, the present work paves the way for the utility of PVA polymer with glass, offering a cost-effective and sustainable approach to gamma radiation shielding in radiation environments.
伽马辐射屏蔽在核电厂、医学成像和太空探索等行业中至关重要。为了在这种环境中屏蔽物体,设计具有柔韧性和高屏蔽能力的材料至关重要。为了提高聚醋酸乙烯酯(PVA)等聚合物的辐射衰减效果,已经将玻璃以不同的比例混入其中。已经对所制造的复合材料进行了伽马射线相互作用研究。已经确定了各种能量(例如 137Cs(661.6keV)和 60Co(1173 和 1332keV))的辐射屏蔽参数,例如质量衰减系数(μ/ρ)。观察到与 PVA 相比,含有玻璃的 PVA 复合材料表现出了改进的伽马辐射屏蔽性能。因此,本工作为使用含有玻璃的 PVA 聚合物铺平了道路,为辐射环境中的伽马辐射屏蔽提供了一种具有成本效益和可持续性的方法。
