Description
Summary:Currently, the utilization of X-ray and Gamma-ray have been widely increased due to their applications such as in the medical (Roentgen, PET, MRI, etc.), industrial and scientific fields. As we know, they have high energy and exposure to X-ray and Gamma-ray will be dangerous for the human body. People who work in the radiation field need protection. In the present work, we have developed glass material for radiation protection. The glass composition was (90-x)TeO2+10ZnF2+xGd2O3 where x is 2, 4, 6, 8, and 10 mol%. The glasses were fabricated using the conventional melt and quenching technique. The mixed material was melted at T=1050 0C for 1.5 hours and annealed at T=500 0C for 1.5 hours. Afterwards, they can be treated at room temperature for characterizations including physical, optical, and the simulation of radiation shielding properties. The physical properties of glass consist of density and molar volume. The glass density laid between 4.15 to 4.75 g/cm3 where the glass density increased by increasing Gd2O3 concentration in the glass system. Meanwhile, the molar volume of glass was found between 36.69 to 38.07 cm3/mol where the molar volume decreased with increasing of Gd2O3 content. The radiation shielding parameter such as mass attenuation coefficient (μm) and effective atomic number (Zeff) have been simulated using Photon Shielding and Dosimetry (PSD) software that is available at https://phy-x.net/PSD. The response of glass material in the energy range of 0.28 – 0.66 MeV has been studied to understand their radiation shielding properties.
