Development of materials for radiation shielding application, which are lightweight, flexible, and robust increases in demand for nuclear radiation facilities including industrial or medical applications. In this paper, three metals (lead, gadolinium, bismuth) doped polymeric compounds (poly-acrylonitrile, polyethylene, and kevlar) were simulated by using theoretical and computational model. It was assumed that lead, gadolinium and bismuth were dispersed homogenously. Both theoretical and computational model were used to calculate the attenuation coefficients of these composite polymeric compounds. At first, theoretical calculations were performed and then computational models were used to simulate the irradiation of the polymeric compounds under various photon energy sources. For each compound, attenuation coefficients were calculated under different percentages and then compared with two computational programs. The work attains novelty as no work is ever reported on the metal/polymeric composites for radiation shielding applications by theoretical-computational technique. This approach was used for the material selection and estimating the possibility of error and to calculate attenuation coefficients under various radiation doses. The research opens new grounds for developing radiation-shielding materials by computational techniques.

辐射屏蔽理论计算模型的建立

开发用于辐射屏蔽应用的材料,该材料轻巧,灵活并且对包括工业或医疗应用在内的核辐射设施的需求不断增长。本文利用理论模型和计算模型对三种金属(铅,g,铋)掺杂的高分子化合物(聚丙烯腈,聚乙烯和凯夫拉尔)进行了模拟。假定铅,g和铋均匀分散。理论模型和计算模型均用于计算这些复合高分子化合物的衰减系数。首先,进行了理论计算,然后使用计算模型来模拟聚合物在各种光子能量源下的辐照。对于每种化合物,在不同的百分比下计算衰减系数,然后与两个计算程序进行比较。这项工作获得了新颖性,因为至今还没有通过理论计算技术报道过用于辐射屏蔽应用的金属/聚合物复合材料的工作。该方法用于材料选择和估计误差的可能性,并计算在各种辐射剂量下的衰减系数。该研究为通过计算技术开发辐射屏蔽材料开辟了新的领域。该方法用于材料选择和估计误差的可能性,并计算在各种辐射剂量下的衰减系数。该研究为通过计算技术开发辐射屏蔽材料开辟了新的领域。该方法用于材料选择和估计误差的可能性,并计算在各种辐射剂量下的衰减系数。该研究为通过计算技术开发辐射屏蔽材料开辟了新的领域。
