“…Afterward, due to the annihilation of the gamma photons during the PP mechanism, Δ 0:5 starts to reduce. [24,25] In the low energy region, the graphs are so close, but in the higher energy range, the TMN1.9 has the largest reduction in comparison with the rest of the glass samples. From the obtained results it can be concluded that the addition of Nd 2 O 3 enhances the shielding ability of the TMNd glasses and reduces the thickness needed for the sample, which is economically practical.…”

“…The cost, noncorrosive, eco-friendly properties, high transparency, non-toxic nature, and good mechanical features are the advantages of using glasses as shielding materials.

Understanding the influence of rare-earth ions in tellurite-rich glass is vital for developing the technology. With this motivation, the present study analyzes the radiation shielding, physical, structural, mechanical, and acoustic features of the tellurite glasses added Nd 2 O 3 rare earth material. Five different glasses coded as TMNd0.0-TMNd1.9 are simulated via MCNPX Monte Carlo code by varying the concentration of neodymium oxide (Nd 2 O 3 ) and the related characteristics are evaluated between 0.01 and 10 MeV. The obtained results reveal that Nd 2 O 3 has a favorable influence on the radiation shielding characteristics of the preferred glass sample. To assess the relation between Nd 2 O 3 concentration in tellurite glass and corresponding structural and mechanical changes in candidate glasses, Makishima-Mackenzie theory is applied and mechanical moduli are extracted. The structure and dimensionality of the preferred samples are derived based on the Bergman and Kantor model for fluid and compositions with the help of the fractal bond connectivity. In addition, the longitudinal velocity (V L ), transverse velocity (V S ), mean velocity (V mean ), and acoustic impedance (Z i ) related to the TMNd glasses are evaluated.

“…Calculated HVL and TVL are listed numerically in table 7. The decrease in both HVL and TVL by increasing Mo content for the present work shielding materials is due to the increase in the density of the sample and hence, the needed thickness in (cm) for better attenuation is decreased [5,26,27,[37][38][39][40]. The evaluation of Z eff and N eff was done using the data from the mass attenuation coefficient and using the mathematical formula mentioned in table 3.…”

The auto combustion technique was employed to synthesis magnesium nano ferrite (MgMoxFe2-xO4). The impact of Mo-doped on the crystal’s structural, morphological, and elastic properties were inspected by applying x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy techniques. Pursuant to the XRD analysis, all samples have a cubic structure with single-phase. The average crystallite size was identified to be in the nanometer range confirmed by SEM and TEM investigations. FTIR data was implemented to assign the force constants of the octahedral and tetrahedral sites. Elastic moduli including the Poisson ratio, Young’s modulus, bulk modulus, and rigidity modulus have been estimated. The division of elastic moduli for all synthesized concentrations was interpreted using binding forces between ions of the cubic lattice spinel. Over and above, the AC conductivity (σ AC) and dielectric properties and their frequency dependence were investigated for the nano ferrites samples as a function of dopant Mo content and temperature. Finally, the radiation shielding capacities of the proposed samples against gamma and fast neutron radiation have been assessed. The findings reveal that the higher the Mo content, the lower the value of the mass attenuation coefficient. There is no significant diversity between the obtained mass attenuation coefficients for the nano and the micro. Among the samples investigated in this study, the highest Mo concentration sample had the largest fast neutron removal cross-section.

The current study aims to report the gamma ray-neutron attenuation parameters of eight types of vinyl ester pumice (V-P) composites for wide energy ranges of 511-2140 keV via MCNPX and FLUKA codes. The radiation shielding properties of these composites were presented graphically and are discussed in detail in this study. From the obtained results, it can be concluded that the MCNPX and FLUKA outcomes are in agreement with each other, and also the FLUKA code can be used as an alternative technique to determine the attenuation features of vinyl ester composites. Besides, the linear attenuation coefficient and total macroscopic cross sections' ( P t ) dependencies on the density and also mass attenuation coefficient were found for all selected samples. To sum up, findings show that composite coded as V-P50 can be a good competitive candidate in terms of gamma rays and neutron shielding.
