Calculation of LAC and HVL values of newly developed barium-borotellurite glass containing different heavy metal oxides using Phy-X/PSD.

This paper examined the radiation shielding characteristics as linear attenuation (LAC) and half-value layer (HVL) of barium-borotellurite glass (BBT), 20BaO-20B2O3-60TeO2, reinforced with 2.5 mol% of different heavy metal oxides (HMOs), X2O3 (X: Bi, Gd, La, Sm). For this purpose, five different glass systems (BBT: reference, BBTB: Bi2O3, BBTG: Gd2O3, BBTL: La2O3, and BBTS: Sm2O3) were explored by performing the newly developed Phy-X/PSD program for theoretical computations. The LAC and the HVL were found out in the photon energies of 0.015 to 15 MeV. Eventually, the findings were compared with some heavyweight concretes and commercial radiation shielding glasses to make a deeper sense. One can report that all HMOs addition contributed to increasing LAC while decreasing HVL thicknesses in our newly developed BBT system. In particular, the BBTB glass provided the best effectiveness in radiation shielding. Further, the BBTB glass system can compete with commercially available glasses, particularly, it could accomplish to overtake lead-oxide containing ones. This study revealed that BBT glasses with differing HMOs can effectively be used in radiation shielding applications. [ABSTRACT FROM AUTHOR]
