The Study of Buildup Factor in the Silicate Glass System Doped with Bismuth Oxide, Barium Oxide and Lead Oxide in Energy Range from 0.015 to 15 MeV using the Phy-X Program

Abstract

In this research, the mass attenuation coefficients and buildup factor had been investigated in the silicate glass system doped with bismuth oxide barium oxide and lead oxide in compositions of 20RmOn: 80SiO2 (where RmOn are Bi2O3, BaO, and PbO) were computed by the Phy-X program in the energy range 0.015 to 15 MeV. From calculated results, the mass attenuation coefficients value of glasses doped with bismuth oxide was higher than barium oxide and lead oxide. The buildup factor of all glasses shows the low value of EBF and EABF at the energy range 0.15 to 1 MeV and beyond 2 MeV, was found that the photoelectric effect and pair production is a major interaction. While, the EBF and EABF values were higher at energy range 0.1 to 2 MeV, due to the Compton scattering effect is a major interaction. As a result of comparing the interaction of the three types of glass, it was found that the glass with the most interaction was bismuth oxide-doped silicate glass. Followed by the lead oxide, and the lowest is barium oxide.
