Polarizability, Optical Basicity, and Photon Attenuation Properties of Ag2O–MoO3–V2O5–TeO2 Glasses: The Role of Silver Oxide

As radiation is an essential tool in various technological applications, searching for a suitable shield is an urgent demand to minimize its damaging effects on human beings. In this research article, we report on the radiation shielding properties of some commercially available polymers namely poly(N-isopropylacrylamide), polyethylene terephthalate, polystyrene, and polycarbonate (denoted by P1, P2, P3, and P4, respectively). The gamma ray attenuation parameters are calculated using the Geant4 simulation, PHITS code, and XCOM program. Half value layer (HVL), linear attenuation coefficient (LAC), gamma dose rate at different energy levels, mean free path (MFP), specific gamma ray constant, effective atomic number (Z eff ) and effective electron density (N eff ), removal cross section for fast neutron, and total cross section for thermal neutron are investigated at energies of 0.01, 0.03, 0.05, 0.07, and 0.1 MeV.The results indicate that the highest LAC values were observed for P2 polymer at 0.1 MeV, while the lowest LAC values were noted for P3 polymer at 0.01 MeV among the studied commercial polymers. The total cross sections of thermal neutrons for the investigated polymers change from 24.0717 to 31.8611 cm −1 . Moreover, the MFPs and HVLs of the investigated polymers were very close to those of ordinary concrete and RS-253-G18 commercial glass, especially at the low energies. This suggests the utility of using the present polymer samples for shielding applications against gamma and/or neutron radiations.

“…The atomic number correlates positively with MAC, causing the highest radiation shielding capability in the glass sample G 1. Even so, the G1 glass can be the most superior attenuation abilities to the other glasses [35][36][37][38][39][40][41][42].…”

Quaternary glasses with a 59B2O3-29SiO2-2LiF-(10 − ) ZnO-TiO2 composition using the melt-quench techniques were prepared. XRD examined the nature of prepared glasses. The FT-IR spectra was studied for the changes in the structure of these glasses. While the density is increased, the molar volume of the glass system is reduced. The velocities and elastic modulus of these glasses were experimentally and theoretically based on the Makishima-Mackenzie model evaluated. Besides, for the studied glasses, the radiation shielding efficiency was investigated by Phy-X/PSD and XCOM software. These glasses were found to have an abnormal attenuation, structural, and density relationship. The mass attenuation coefficient (μ/ρ), linear attenuation coefficient (LAC), half-value layer (HVL), tenth value layer (TVL), and effective atomic number (Zeff), of glasses, have been designed to simulate for gamma photon energies between 0.015 and 15 MeV. MAC values calculated using Phy-X/PSD and XCOM were compared and was observed in good agreement with the other.

“…Simulation is a method that saves researchers much time and effort by using a computer to form the required observations without having to obtain them experimentally and without biasing the obtained results or their accuracy. One of the most important and most common simulation methods in radio physics is the Monte Carlo method [24,25]. For example, Al-Hadeethi et al [26] used Geant4 to study the radiative attenuation factors of borate glasses containing WO 3 -ZnO-PbO.…”

We analyzed the mechanical properties and radiation-shielding performance of a lithium zinc bismuth silicate glass system. The composition of these glasses is 20ZnO-30Li2O-(50-x)SiO2-xBi2O3 (x varies between 10 and 40 mol%). The mechanical properties of the investigated glass system, such as Young’s modulus (E), bulk modulus (K), shear modulus (S), and longitudinal modulus (L), were determined using the Makishima–Mackenzie model. The elastic moduli gradually decreased with the addition of Bi2O3. E decreased from 46 to 31 GPa, K decreased from 27 to 14 GPa, S decreased from 19 to 14 GPa, and L decreased from 52 to 32 GPa as Bi2O3 was substituted for SiO2. The mass attenuation coefficient (MAC) was investigated at energies between 0.284 and 1.33 MeV to understand the radiation-shielding performance of the glasses. The MAC value increased when SiO2 was replaced by Bi2O3. We found that the effect of Bi2O3 on MAC values was noticeably stronger at energies of 0.284 and 0.347 MeV, while the effect of Bi2O3 on MAC values became weaker as energy increased. The linear attenuation coefficient (LAC) results demonstrated that if the samples were exposed to low-energy photons, the glass could prevent the penetration of photons, and thus, the glass samples were effective in radiation protection. The LAC values for the lowest- and highest-density samples changed from 0.998 to 1.976 cm−1 (at 0.284 MeV) and from 0.286 to 0.424 cm−1 (at 0.826 MeV). According to the radiation-shielding results, the thick, high-density glass sample has special and distinctive shielding properties.
