“…These methods depend on Beer-Lambert law that can applied in the case of narrow beam geometry [12,13]. However, the experimental is restricted to limited photon energies that can not be found easily or cheaply [14][15][16]. The simulation technique is proposed as a strong alternative to the experiment.…”

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.

Halloysite is a clay mineral found in the natural environment and it has many applications in chemistry and medical fields. The linear attenuation coefficient (µ) for halloysite nanotubes minerals simulated using MCNP 5 code between 0.015 and 15 MeV. Moreover, the linear attenuation coefficient calculated for all selected samples using Phys-X/PDS program. Furthermore, some important shielding parameters that described the penetration and interaction of gamma rays with halloysite atoms, such as the half-value (HVL), effective atomic number (Z eff), and exposure buildup factor (EBF) were calculated for gamma rays between 0.015 and 15 MeV.

“…While as the energy increases, the probability of the photoelectric absorption process is reduced and other two processes namely Compton scattering (Table 6) and pair production (P.P) ( Table 7 and Fig. 13) become the most dominate interactions, where this occurs specifically for E > 1.022 MeV [44,45]. These results (dependent of µ/ρ on the photon energy) are corresponding with the recently published literature on different materials like rocks [44], glasses [46][47][48][49][50], bricks [51], and amino acids [52].…”

In the present study, the optical characterization of borate glasses with composition 35Li 2 O − 10ZnO − 55B 2 O 3 − xMnO 2 : x = 0, 0.5, 1.0, 1.5, and 2.0 wt% has been investigated. The absorption spectra measurements within the wavelength domain 200-1000 nm have been carried out. The optical energy gap of the investigated samples using the absorption spectrum fitting (ASF) model has been calculated. The molar refraction, molar polarizability, reflection loss, optical transmission for the samples were estimated. The metallization criterion, dielectric constant, refractive index, and energy band metallization criterion for the studied glasses were estimated. Magnetic property measurements for all glass samples were carried out at 300 K. Additionally, the prospects of gamma-ray interactions with the investigated glasses have been achieved through studying the total mass attenuation, coherent, Compton, photoelectric, and pair production interactions at photon energy in the range of 0.356-1.330 MeV. Results reveal that the optical and magnetic properties of the investigated glasses change with changing the MnO 2 concentration. Studied glasses can be used as a candidate for optical fiber and optical devices application. In the other hand, at lower gamma photon energy range, the photoelectric absorption dominates with the glasses, while as the energy increases, the probability of Compton scattering and pair production become the most dominate interactions.
