AA2024 is a lightweight alloy characterized by high strength, excellent fracture toughness, and outstanding damage tolerance. In this study, SiC and B4C were incorporated into AA2024 in varying weight fractions (1, 3, 5, 7, 15, and 30 %) to investigate their potential use as radiation shielding materials. Unlike traditional shielding materials such as lead, these composites offer advantages including lower toxicity, reduced weight, and improved mechanical strength, while maintaining high radiation attenuation capability. Their suitability as alternatives to lead was evaluated. The gamma and neutron attenuation properties of the composites were theoretically analyzed using the Phy-X/PSD online program. Additionally, optical emission spectrometry, X-ray diffraction (XRD), and particle size analyses were performed on the powders used in the study. For AA2024+(0–30 %)B4C composites, the half-value layer (HVL) values ranged from 0 to 0.126 cm, while for AA2024+(0–30 %)SiC composites, the HVL values ranged from 0 to 0.110 cm. Among the tested samples, AA2024 + 30 %B4C exhibited the lowest gamma shielding performance, whereas AA2024 + 30 %B4C showed the highest neutron shielding efficiency.
