Abstract

In this study, the absorption capability and the weight of various radiation-shielding materials were evaluated, for applications as alternatives to lead garments. Toxicity, atomic number, density, K-edge absorption energy and availability of elements that can serve as an alternative to lead, including tin, antimony, bismuth and tungsten, were considered. The attenuation coefficients of these elements were determined using the XCOM software package, and these metals were mixed with polymers at 50, 70, 80 and 85 % mass ratios. It can be concluded that all of the new shielding materials used in the study can be used for a diagnostic range of X-rays. However, they were compared with the commercial lead garments in terms of weight and attenuation coefficient; the 85 % samples were lighter than a 0.5-mm lead garment and provided superior radiation protection, which demonstrates its potential for commercial applications.

摘要

在本研究中，评估了各种辐射屏蔽材料的吸收能力和重量，以用作铅衣的替代品。考虑了毒性、原子序数、密度、K 边吸收能量以及可替代铅的元素（包括锡、锑、铋和钨）的可用性。使用 XCOM 软件包确定了这些元素的衰减系数，并将这些金属与聚合物按质量比 50%、70%、80%和 85%混合。可以得出结论，该研究中使用的所有新型屏蔽材料均可用于 X 射线诊断范围。然而，在重量和衰减系数方面将它们与商用铅衣进行了比较；85%的样品比 0.5 毫米厚的铅衣更轻，并提供了更好的辐射防护，这证明了其商业应用潜力。
