Transmission Factor (TF) Behavior of Bi2O3–TeO2–Na2O–TiO2–ZnO Glass System: A Monte Carlo Simulation Study

Abstract

The main objective of the present work was to assess the gamma radiation shielding competencies and gamma radiation transmission factors (TFs) for some tellurite glasses in the form of Bi2O3–TeO2–Na2O–TiO2–ZnO. MCNPX general-purpose Monte Carlo code (version 2.6.0) was utilized for the determination of TF values at various well-known radioisotope energies for different glass thicknesses from 0.5 cm to 3 cm. Moreover, some important gamma ray shielding properties were also determined in the 0.015–15 MeV energy range. The results show that glass densities were improved from 5.401 g/cm3 to 6.138 g·cm3 as a function of Bi2O3 increment in the glass composition. A S5 glass sample with the maximum Bi2O3 additive was reported with superior gamma ray shielding properties among the studied glasses. It can be concluded that Bi2O3 can be used as a functional tool in terms of improving glass density and, accordingly, gamma ray shielding attenuation properties of tellurite glasses, where the role Bi2O3 is also critical for other material properties, such as structural, optical, and mechanical.

Transmission factors, mechanical, and gamma ray attenuation properties of barium-phosphate-tungsten glasses: Incorporation impact of WO3

“…5 shows the linear attenuation coefficient's evolution with respect to various energy values. Depending on the photon's energy, a variety of interactions may take place when it comes into contact with matter [46][47][48][49]. The photoelectric effect (PE), for example, is the most common type interaction in the lower energy band.…”

Physical Features of High-Density Barium–Tungstate–Phosphate (BTP) Glasses: Elastic Moduli, and Gamma Transmission Factors

“…Recent investigations have stressed that glass shields [14][15][16][17][18][19][20] are one of the most ambitious materials that might be used as an alternative for conventional materials that are disadvantaged in certain ways. Researchers in the literature [21][22][23][24][25][26][27][28][29][30] are particularly interested in glass structures because of the high permeability they provide and the exceptional mechanical properties they possess. It has also been pushed to a position where it is emphasized and developed in daily radiation safety practice because of the non-toxic nature of glasses and the chemical compositions that may be synthesized at high densities.…”
