Abstract :Composite materials theoretically designed by adding CoSO4 ceramic material to Al 2124 alloy in proportions of 3-6-9-12% by weight were analyzed for gamma transmittance properties in the energy range of 1 keV to 1x10⁶ keV using the EpiXS program. The mean free path (MFP), half-value layer (HVL), and linear attenuation coefficient (LAC) parameters were analyzed using gamma radiation sources, including 241Am, 133Ba, 109Cd, 57Co, 60Co, 152Eu, and 137Cs. As a result of the analysis, it was determined that with the increase in CoSO4 by weight in Al 2124, the LAC values of the composite materials increased, while the HVL and MFP values decreased. In the photon energy range from 1 keV to 1x106 keV, the Al 2124 material had the highest HVL value with values ranging from approximately 1.49x10-4 cm to 7.72 cm, while it had the lowest LAC values with values ranging from approximately 4661.03 cm-1 to 0.09 cm-1. The highest LAC values were obtained by the Al 2124+ 12% CoSO4 composite material, which has the highest CoSO4 ratio by weight, with LAC values ranging from approximately 6417.7 cm-1 to 0.095 cm-1. Due to its best photon shielding performance, its HVL had values ranging from approximately 1.08x10-4 cm to 7.3 cm.
