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

Multilayer polymers have potential applications in various fields 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. [ABSTRACT FROM AUTHOR]
