Multi-walled carbon nanotubes (MWCNT) and magnetic nanoparticles are widely used to improve the mechanical, electrical and radiation attenuation properties of composite materials. It is important to comparatively investigate the ionizing radiation attenuation performance of polymer composites reinforced with MWCNT and cobalt-containing magnetic nanoparticles. In the experiments, measurements were made using Co-60, Sr-90, Am-241 and Cs-137 sources using gamma, beta and neutron transmission methods. The effects of cobalt-containing magnetic reinforcement particles and nanoparticle (MWCNT) additives on the radiation absorption capacity of polymer samples were evaluated by analyzing the linear attenuation coefficient (µ) and half-value thickness (HVL). By examining the radiation permeability properties of the polymer composite structure, HVL values were determined and the gamma,beta and neutron radiation absorption capacity was investigated comparatively. This study includes results for the development of lightweight and effective radiation shielding materials. Keyphrases: Gamma Transmission, MWCNT, PMMA, neutrons, radiation shielding
