“…For c-rays attenuation characteristic study for any material, mass attenuation coefficient (l/q) is an important physical parameter. Additionally, halfvalue layer (HVL), tenth-value layer (TVL), effective electron density (N eff ), effective atomic number (Z eff ), mean free path (MFP), exposure buildup factor (EBF), and energy absorption buildup factor (EABF) parameters are vital in understanding gamma radiation interaction through photoelectric absorption, Compton scattering, Rayleigh scattering, and pair production mechanisms with shielding material [6][7][8][9]. For the last few years, numerous research groups have been reported on gamma-ray shielding features of different glass systems using theoretical approaches and/or experimental methods.…”

Gamma-rays and fast and thermal neutron attenuation features of (Bi 2 O 3 ) x -(TeO 2 ) (100-x) (where x = 5, 8, 10, 12, and 15 mol%) and [(TeO 2 ) 0.7 -(B 2 O 3 ) 0.3 ] (1-x) -(Bi 2 O 3 ) x (where x = 0.05, 0.10, 0,15, 0.20, 0.25, and 0.3 mol%) glass systems have been explored and compared. For all samples, mass attenuation coefficients (l/ q) are estimated within 0.015-15 MeV photon energy range by MCNP5 simulation code and correlated with WinXCom results, which showed a satisfactory agreement between computed l/q values by these both methods. Additionally, effective atomic number (Z eff ), effective electron density (N eff ), half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), total atomic cross-section (r a ), and total electronic cross-section (r e ) are calculated by utilizing l/q values. The l/q, Z eff , and N eff are energy dependent and have higher values at the lowest energy and smaller values at higher energies. Moreover, using the G-P fitting method as a function of penetration depth (up to 40 mfp) and incident photon energy (0.015-15 MeV range), exposure buildup factors (EBFs)

“…On the other hand, the significant use of x-ray and gamma-ray in many fields requires hard efforts to search for new materials which are economic, environment friendly, and proper protective against x-ray and gamma-ray. In this regards, several authors reported different type of glasses as promising shielding materials [7][8][9][10][11]. Sayyed [7] proposed some HMO glasses such as PbO, MgO, Ag 2 O, Nb 2 O 5 , ZnO and BaO for gamma-ray applications.…”

This paper examines the gamma-ray shielding features of some selected tellurite-based glasses in the form of xMoO 3 (100−x)TeO 2 (20 x 50 mol%). Mass attenuation coefficients (μ m ) of these glasses have been calculated using Geant4 toolkit and XCOM program for photon energy range of 1 keV-1000 MeV. The correlation factor (R 2 ) between these two methods was found to be almost one. Shielding effectiveness for these glasses has been estimated by computing half value layer (HVL), effective atomic number (Z eff ), and mean free paths (MFP). It was noticed that the heavy metal oxide of TeO 2 plays an important role in improving the shielding effectiveness of the glasses. The Mo20Te80 glass has shown the promising properties to serve for gamma ray protection applications as compared with many conventional concretes and other newly developed glasses.

“…However, HgI has the lowest value as the quality of a photon's interaction is enhanced by a denser sample rather than a lower density one. Figure 3b shows HVL results for the studied samples compared with chromite, ferrite, magnetite, barite [38,39], RS-520, RS-360, and RS-253-G18 [38,42], the three commercial shielding glasses. As illustrated, all investigated samples have HVL values lower than the corresponding values of the other set of comparison samples.…”

This analysis aims to determine photon attenuation for five different ternary and binary iodide compounds using Phy-X/PSD software. For a broad range of photon energies between 0.015 and 15 MeV, the mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), half-value layer (HVL), tenth-value layer (TVL), and mean free path (MFP) for the samples of Cu2HgI4, Ag2HgI4, CuI, AgI, and HgI were calculated. For illustration, the following values of TVL apply at 1 MeV: S1: 6.062 cm, S2: 6.209 cm, S3: 6.929 cm, S4: 6.897 cm, and S5: 4.568 cm. Some important parameters, such as total atomic cross-sections (ACS), electronic cross-sections (ECS), the effective atomic numbers (Zeff), effective electron density (Neff), and effective conductivity (Ceff) of the samples were also calculated. Additionally, exposure buildup factors (EBF) and energy-absorption buildup factor (EABF) were estimated. These data on the radiation characteristics of our samples could be useful for gamma attenuation. The HgI sample has the highest FNRCS values (0.0892) relative to the other tested samples showing good neutron attenuation features. The CuI sample shows low gamma attenuation features; in contrast, it shows high neutron attenuation features.
