Abstract

This research, the photons shielding parameters such as mass attenuation coefficients (μm), effective atomic number (Zeff) and Kerma relative to air (Ka) for Bi2O3 based TeO2-B2O3-Bi2O3 glass system have been simulated by WinXCom software program at energies of 10-3-105 MeV. Also, buildup factors (BFs) have been estimated in wide energy ranging 15 keV-15 MeV for penetration depths (PD) until 40 mean free path (mfp). The results of the glass system in formula (70-x)TeO2-30B2O3-xBi2O3 at x = 10, 20, 30, 40 and 50 mol% exhibited that Bi2O3 partial replacement of TeO2 adjusts photons attenuation behaviors for get better. In addition, charged particles (proton: H+ and alpha particles: He2+) shielding parameters such as mass sopping power (MSP) and projected range (PR) were evaluated using SRIM software program at kinetic energy ranging 10 keV-10 MeV. The results found that the 20TeO2-30B2O3-50Bi2O3 glass sample which had the highest Bi2O3 content showed the largest μm, Zeff and BFs values, while the MSP and the PR were the lowest values. These results indicated that glass sample with high Bi2O3 content is superb for photons attenuation while low Bi2O3 content is excellent for H+ and He2+ shielding glass. The results of this research can be useful in enhancing the optimization of ionizing radiation shielding materials. [ABSTRACT FROM AUTHOR]
