The successful synthesis of the novel composition glass system with the empirical formula (9CdO + 11SiO2 + 64B2O3 +(2-x) LiF +(14+x) MoO3 for x = 0, 0.5, 1, 1.5, and 2 mole %) has been fabricated. The density increased from 2.87 to 3.25 g/cm3 while the molar volume decreased from 29.04 to 26.37 m3/mol. The longitudinal ( V l ) increase from 4740 to 4855 m/s and shear ( V t ) velocity increase from 2635 to 2745 m/s. Elastic moduli of the glass sample also exhibit an increasing behavior with greater MoO3 concentration. Studies comparing experimental and theoretical elastic moduli reveal the same behavior. The Phy-X/PSD database was utilized to calculate the radiation protection values. With the substitution of MoO3 for LiF, the fundamental radiation shielding and significant parameters ( M A C , L A C , Z eff , and ∑ R ) increase as G 5> G 4 > G 3 > G 2 > G 1. According to the results, the G 5 sample had the lowest HVL, TVL, and MFP of all the glasses, which can be ascribed to the sample's high density due to its high MoO3 content. According to this investigation, the G5 sample has the best radiation properties when photon energy is increased. [ABSTRACT FROM AUTHOR] |
