摘要：
The focus of the current research is to see the effectiveness of some quaternary ChGs as shielding materials for incoming photon energy in the range of 0.015-15.0 MeV. The ChGs addressed in this investigation belong to a quaternary glass system of Se78-xTe20Sn2Znx (x = 0, 2, 4, 6). The online Phy-X/PSD program has been used to deduce several safety factors. The MAC values of the studied glass have the following sequential order: MAC(Zn-0) > MAC(Zn-2) > MAC(Zn-4) > MAC(Zn-6). The most intriguing results are that they have values that are better for shielding than some commercial and conventional glasses (e.g., at E = 1.0 MeV, LAC(RS-520) < LAC(RS-253-G18) < LAC(Zn-0) < LAC(Zn-2) < LAC(Zn-4) < LAC(Zn-6) < LAC(Zn-4) < LAC(Zn-6)). Further, we have determined various shielding parameters (e.g., 0.02 < Half-Value Layer < 4.083 cm(-1), 0.03 < mean free path <6.90) as well as the mechanical properties (e.g., 40.71 < bulk modulus < 50.55 GPa, 12.16 < shear modulus <15.91 GPa, 49.83 < longitudinal modulus <62.47 GPa, 0.358 < Poisson's ratio < 0.368, and 0.032 < micro-hardness <0.0349 GPa). It is also discussed how replacing Se atoms with zinc affects the shielding properties of the SeTeSn glass.
