Radiation shielding study of tellurite tungsten glasses with different antimony oxide as transparent shielding materials using MCNPX code

The radiation shielding performance of tellurite tungsten glasses with different antimony oxide (Sb2PO3) content was studied using Monte Carlo simulation MCNPX and WinXCOM software. The mass attenuation coefficients were computed for photon energies of 0.662, 1.173, 1.274 and 1.332 MeV. Moreover, The transmission factor of the selected glasses was calculated at a different thickness from the incident and transmitted photons. It was found that the transmission factor of the investigated glasses lies within 0.11-0.28 range. Also, it was found that the MCNPX and WinXCOM results were matched with each other. It can also be concluded that the high density TSW5 glass sample has the maximum shielding effect over the other samples because of the high weight fraction of the highest atomic numbers (i.e. W, Z = 74) as well as its high density.
