Abstract :The aim of this research is to examine the radiation shielding properties of 5B2O3-40SiO2-insert ignore into journalissuearticles values(55-x);Al2O3-xBaO insert ignore into journalissuearticles values(BSABa-x); glass systems, which are containing barium and aluminum oxide added to borosilicate glasses, with varying from 25 to 34 weight fractions. Shielding parameters, such as linear attenuation coefficients insert ignore into journalissuearticles values(LAC);, mass attenuation coefficients insert ignore into journalissuearticles values(MAC);, mean free path insert ignore into journalissuearticles values(MFP);, effective atomic number insert ignore into journalissuearticles values(Zeff);, effective electron density insert ignore into journalissuearticles values(Neff);, half-value layer insert ignore into journalissuearticles values(HVL);, tenth-value layer insert ignore into journalissuearticles values(TVL);, effective atomic weight insert ignore into journalissuearticles values(Aeff);, exposure buildup factors insert ignore into journalissuearticles values(EBF); and energy absorption buildup factors insert ignore into journalissuearticles values(EABF); enable us to obtain information about the radiation shielding power of composite glass material groups. Therefore, the mass attenuation coefficients insert ignore into journalissuearticles values(MAC);, for the 0.015–15 MeV gamma-ray energies are obtained by using the Py-MLBUF online software to determine photon shielding parameters of BSABa-x glasses. The results are shown that the glass which contains higher BaO concentration has higher mass attenuation coefficients. BSABa-34 glass has the highest MACs, ranging from 0.111 cm2/g to 90.400 cm2/g, while BSABa-25 glass has the lowest values, ranging from 0.099 cm2/g to 69.000 cm2/g. The BSABa-34 glass with the highest BaO contribution has the thinnest MFP and HVL values. In addition, photon buildup is minimized by adding BaO to the BSABa-x glasses. Accordingly, we can conclude that adding BaO to aluminum borosilicate glasses at increasing rates, improves nuclear radiation resistance properties.
