Investigation of The Gamma Ray Shielding Behaviour of (90-x)TeO2—xMoO3—10ZnO Glass System Using Geant4 Simulation Code and WinXCOM Database
Journal Title: Cumhuriyet Science journal - Year 2019, Vol 40, Issue 3
Abstract
In this study, mass attenuation coefficients (µm), transmission fractions (T), mean free path (MFP) and half value layer (HVL) of the (90-x)TeO2—xMoO3—10ZnO glass system (x=10, 20 and 30 mol%) were calculated at the gamma ray photon energies of 356 keV, 662 keV, 1173 keV and 1330 keV. Shielding parameters of the glass system were calculated from the Monte Carlo simulations carried out with the Geant4 model of a high purity germanium (HPGe) detector and from the WinXCOM database software. The used Geant4 model was validated by comparing the experimentally determined mass attenuation values of the PbO—BaO—B2O3 glass system to the values calculated with Geant4. The findings of the present study reveals that the glass system containing 10% mol MoO3 exhibits better photon shielding performance compared to the glass with 30% mol of MoO3 due to the higher amount of TeO2 existed in its chemical formula.
