Investigation of Gamma Radiation Shielding Properties of High-Z-Doped Multilayer PVA Polymers

Abstract

Multilayer polymers have potential applications in various elds for radiation shielding. It is quite interesting to investigate the shielding properties of polymer composites in a combined manner. In the present investigations, the high-Z-doped PVA polymers such as PVA+50%Bi2O3 and PVA+50%Na2O4W were selected, and the multilayer buildup factors were calculated for various combinations of high-Z-doped multilayer PVA polymers using the Py-MLBUF software. The PVA+50%Bi2O3 and PVA+50%Na2O4W are coded, respectively, as A and B. The BA and BBA combinations have the potential to replace a single layer of high-Z-doped PVA polymers, and these combinations can be used as gamma-ray shields.
