The influence of heavy elements on the ionizing radiation shielding efficiency and elastic properties of some tellurite glasses: Theoretical investigation

Abstract

The impact of adding PbO and WO3 on the mechanical properties and radiation shielding efficiency of 4 different glass samples labeled as TWP1, TWP2, TWP3, and TWP4 (samples codes) was studied via the Makishima and Mackenzie model (MMD), Rocherulle model (RD), XCOM database, FLUKA code, and Phys-X/PSD software. According to MMD, Young's (Y), bulk (K), shear (G) modulus values increase from 59.13 to 62.80 GPa, from 37.76 to 43.86 GPa, from 25.48 to 26.55 GPa, and from 71.73 to 79.26 GPa for TWP1 and TWP4 glasses, respectively. 277.833, 358.768, 465.048 and 570.786 cm−1 values are the highest linear attenuation coefficient (μ) values for TWP1, TWP2, TWP3 and TWP4 glasses at 0.015 MeV. The results refer that the TWP4 glass sample has the highest radiation shielding and mechanical properties. The results indicated that the addition of lead and tungsten to the investigated samples improves their elastic and radiation shielding properties. Thus, the TWP4 sample is the best compared to the other glass samples. © 2020 The Authors
