Simulation of shielding parameters for TeO 2 -WO 3 -GeO 2 glasses using FLUKA code

Abstract

This paper aimed to report the results on the investigation of photon attenuation parameters for TeO 2 -WO 3 -GeO 2 glasses using FLUKA Monte Carlo code. In order to test the validity of the present code, the computational values of mass attenuation coefficients have been in confirmation with those of both previously published experimental data (MoO 3 -B 2 O 3 -Bi 2 O 3 ) and XCOM database at various energies between 356 and 1330 keV. The relative deviation between FLUKA and experimental data is below 5.19% while the difference between the present code and XCOM database is found to be almost 2%. Therefore, the estimated results are in good agreement to each other and exhibited that FLUKA simulation is an alternative technique in determining the shielding performance of the present glass system. Additionally, mean free path and half-value layer results were calculated and it was concluded that among the selected glasses, TeWGe5 sample has superior shielding effectiveness.
