Influence of ZnO to the physical, elastic and gamma radiation shielding properties of the tellurite glass system using MCNP-5 simulation code

The main goals of this current work are to study the elastic and radiation shielding properties of seven different compositions of ZnO-TeO2 transparent glass and characterize them using density, molar volume, X-ray diffraction (XRD), ultrasonic technique, and Monte Carlo simulation method. From the ultrasonic wave measurement result, the substitution of ZnO, which works as a network modifier into the TeO2 glass systems, would break up the Te-O-Te bonds of TeO4 into the form TeO3 along with all the formation of NBO's which give the impact on the elastic moduli analysis. The radiation shielding features for the fabricated samples were studied using the MCNP-5 code. The difference between the MCNP and XCOM results was found to be less than 3%. The highest linear attenuation coefficient (LAC) for all ZT glasses achieved at 0.015 MeV and varied between 202.199 and 239.607 cm-1 for glasses coded 0 ZT and 30ZT, respectively.
