Investigation of The Gamma Ray Shielding Behaviour of (90-x)TeO2—xMoO3—10ZnO Glass System Using Geant4 Simulation Code and WinXCOM Database
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.
