Shielding Behaviour of TiO2 Reinforced Composite Materials Against 4 MeV Energy Photons and Neutrons

In order to eliminate or minimize the possible negative effects that may arise due to the use of increased artificial radiation, the radiation permeability properties of Al 6082 alloy material, Al 6082+5% TiO2, Al+15% TiO2, and Al 6082+25% TiO2 metal matrix composite materials against 4 MeV fast neutron and gamma radiation were analyzed in the NGCal program. Mass attenuation coefficient (MAC), mean free path (MFP), linear attenuation coefficient (LAC), tenth value layer (TVL), and half value layer (HVL) and parameters were analyzed for both fast neutron and gamma radiation. As a result of the analysis of 4 MeV energy fast neutron and gamma radiation, the linear attenuation values of the material against both fast neutron and photon increased depending on the increasing reinforcement ratio, while the half value layer, tenth value layer and mean free path values decreased. While the LAC values of Al 6082, Al 6082+5% TiO2, Al+15% TiO2, Al 6082+25% TiO2 materials against fast neutrons vary between approximately 0.00074 cm-1 and 0.0173 cm-1, their LAC values against photons vary between 0.084 cm-1 and 0.96 cm-1.
