In this study, four different glass samples encoded VTBNd0.0, VTBNd0.5, VTBNd1.0, and VTBNd1.5 based on 74.75 TeO\({}_{2}\)-0.25V\({}_{2}\)O\({}_{5}\)-(25 - x)B\({}_{2}\)O\({}_{3}\)-xNd\({}_{2}\)O\({}_{3}\) (x = 0, 0.5, 1, 1.5 mol\(\%\)) systems were tested for their feasibility for nuclear radiation shielding utilizations. The experiments on optical and structural properties were widely reported, which included alloys of different composition. In a previous paper, [PERSON] [1] discussed the effect of B\({}_{2}\)O\({}_{3}\) and Nd\({}_{2}\)O\({}_{3}\) substitution on the optical, structural, and thermal properties of these glass samples. He discovered a personal association between Nd\({}_{2}\)O\({}_{3}\) reinforcement and the optical properties and thermal and structural properties of 74.75 TeO\({}_{2}\)-0.25V\({}_{2}\)O\({}_{5}\)-(25 - x)B\({}_{2}\)O\({}_{3}\)-xNd\({}_{2}\)O\({}_{3}\) (x = 0, 0.5, 1, 1.5 mol\(\%\)) oxide glasses. To fulfil the demands of IAEA and WHO organizations, the importance of alternative shielding materials is rising. This study attempted to investigate the connection between the intriguing results in the Nd\({}_{2}\)O\({}_{3}\) reinforced oxide glasses and their nuclear radiation shielding properties. A first move was made in evaluating availability concentrations for alloys in a 0.015-15 MeV range, using a general-purpose Monte Carlo method and Phy-X software. The selected energy range is a standard energy range of theoretical gamma ray shielding calculations, where the critical behaviors at the low, middle, and high energy region depending on dominant interaction processes such as photoelectric effect, Compton scattering, and pair production can be observed. The word 'LAC' (\(\mu\)) is used to measure the shielding efficacy of glass samples. Density relies on the effectiveness of shielding compounds and the energy of the gamma rays. Figure 2 shows the interaction between the photon energy of VTBNd0.0, VTBNd0.5, VTBNd1.0, and VTBNd1.5 samples. In Figure 2, the energy zone's effect on the variance of the LAC value was affected by the photoelectric effect, Compton scattering, and pair production mechanisms. This result occurs due to the nature of radiation's interaction with matter. At low energies, the LAC value is decreased because of photo adsorption. In the mid-energy region, Compton scattering was the dominant interaction in the measurement pattern. However, the highest LAC amount was calculated in the VTBNd1.5 sample, which has the highest concentration of Nd\({}_{2}\)O\({}_{3}\). The mass attenuation coefficient (MAC) of the specified substance is density-independent and unique. Figure 3 displays the variation of obtained MAC values against photon energy (E). A variety of gamma-ray radiation and chemical compositions of attenuator glass have changed the rate of difference of MAC values. The landscape of the MAC data reveals noticeable trends in distinct areas. In the low energy area where the photoelectric effect determines how much gamma ray is absorbed, the absorption decreased significantly. Compton scattering dominance showed statistically substantial declines from MAC values. It appears that the VTBNd1.5 sample has higher MAC values at all incident photon energies. In particular, the findings for VTBNd0.0, VTBNd0.5, VTBNd1.0, and VTBNd1.5 samples were reported as 0.4926, 0.4977, 0.5027, and 0.5075 at 0.15 MeV photon energy, respectively. Moreover, MAC values were reported as 0.0353, 0.0355, 0.0356, and 0.0358 at 15 MeV photon energy for the studied glass samples in the same order. The condition obtained in both low and high energy areas can be explained by the inclusion of the largest amount of Nd\({}_{2}\)O\({}_{3}\) in the glass composition because of its high atomic number. Similar results were reported by [PERSON] et al. [13]. Their results showed that Bi\({}_{2}\)O\({}_{3}\) reinforcement in the V\({}_{2}\)O\({}_{5}\)-TeO\({}_{2}\) glass system directly increased the mass attenuation coefficients of the studied glasses.
