Abstract

This study aimed to perform an extensive characterization of a 74.75TeO2–0.25V2O5–(25 − x)B2O3-xNd2O3 glass system with (x = 0, 0.5, 1.0, and 1.5 mol%) for radiation shielding properties. Linear and mass attenuation coefficients were determined using Phy-X PSD software and compared with the simulation using Monte Carlo software MCNPX (version 2.7.0). Half value layer, mean free path, tenth value layer, effective atomic number, exposure buildup factor, and energy absorption buildup factors of VTBNd0.0, VTBNd0.5, VTBNd1.0, and VTBNd1.5 glasses were determined, respectively. The results showed that boron (III) oxide and neodymium (III) oxide substitution has an obvious impact on the gamma ray attenuation properties of the studied glasses. It can be concluded that the VTBNd1.5 sample with the highest content of neodymium (III) oxide (1.5 mol%) is the superior sample for shielding of gamma radiation in the investigated energy range.

Highlights

The multitude of physical, thermal, optical, and structural properties of glasses make them far better than other goods
Four different glass samples encoded VTBNd0.0, VTBNd0.5, VTBNd1.0, and VTBNd1.5 based on 74.75TeO2 –0.25V2 O5 –(25 − x)B2 O3 –xNd2 O3 (x = 0, 0.5, 1, 1.5 mol%)
Systems were tested for their feasibility for nuclear radiation shielding utilizations

Summary

Introduction

The multitude of physical, thermal, optical, and structural properties of glasses make them far better than other goods. They are manufactured at different temperatures, which led to the increase in studies where they were used in optoelectronic devices and in other industries. A large number of these experiments are dedicated to glasses comprising rare earth metal oxides [1,2,3]. These low-cost glasses are ideal hosts for rare earth elements and are excellent materials for optoelectronics. Tellurium glasses exhibit low melting temperatures, high transmittance, high refractive indices, and chemical and mechanical tolerance
