Effect of Increasing Weight of SiC Ceramic on Radiation Shielding of Al 2219

Artificial radiation has many disadvantages as well as benefits. In order to eliminate or minimize these disadvantages and to be an alternative to radiation shield materials used, Al 2219 alloy material, Al 2219+% 5 SiC, Al 2219+% 10 SiC, Al 2219+% 15 SiC metal matrix composite material's mass attenuation coefficient (MAC), mean free path (MFP), linear attenuation coefficient (LAC), half value layer (HVL), fast neutron cross section (FNRC) and tenth value layer (TVL) parameters were analyzed in Phy-x/PSD program. Powder grain structure of Al 2219 and SiC powders were analyzed by scanning electron microscope (SEM) and powder grain size analysis was performed by Malvern Mastersizer 3000 device. As a result of the analysis of fast neutron and gamma radiations, linear attenuation values of the material against photons increased depending on the increasing reinforcement ratio, while HVL, TVL and MFP values decreased. The FNRC values of Al 2219 alloy material, Al 2219+5% SiC, Al 2219+10% SiC, Al 2219+15% SiC materials were calculated as 0.081 cm-1, 0.083 cm-1, 0.084 cm-1 and 0.084 cm-1, respectively.
