Abstract

The use of heavy metal oxide as shielding material attracted great interest among researchers in recent years due to its high shielding efficiency without loss of transparency, good physical properties, good thermal stability, and good optical properties. In this work, the physical, optical, and shielding effectiveness of tellurite glass with composition

Highlights

The use of ionizing radiation in the medical field increases dramatically over the past few years due to the increasing use of computed tomography examination in addition to the medical application of radiation in cancer treatment [1,2,3]
The oxygen packing density (OPD), the molar refraction (Rm), and the molar electronic polarizability of the prepared sample compared with some commercially available glass shielding materials such as that developed by Schott Co., Germany standard shielding glass materials (RS 253 G18, RS 520, and RS 360) [31]
The measured refractive index at wavelength 535 nm of the prepared sample recorded the highest value compared with the refractive indices of standard materials taken from the literature [31]

Summary

Introduction

The use of ionizing radiation in the medical field increases dramatically over the past few years due to the increasing use of computed tomography examination in addition to the medical application of radiation in cancer treatment [1,2,3]. Et al [16] have studied the shielding effectiveness of four novel tellurite-based glasses samples doped with oxide metals Lakshminarayana, et al [22] have studied the radiation shielding effectiveness of borosilicate glasses doped Tm3+ ions for gamma application. Their results indicate that the sample that contains the highest mole concentration of Tm2O3 has the greater ability to attenuate gamma-rays. The probability of photon interaction with material can be characterized by the total atom cross-section ( sa ) and total electronic cross-section ( sa ) using the following relations [29,30]:
