Polystyrene-metal composite materials were manufactured. Composite materials are made of polystyrene, which has been reinforced with highly dispersed powder-like aluminum. Tungsten or steel powder was applied as a radiation shielding additive. The radiation-protective characteristics of composite materials were studied using sources of ionizing radiation 241Am and 152Eu. Calculations of the relative attenuation of the absorbed dose of gamma radiation for protective materials with different mass composition have been performed. A comparison of the protective characteristics obtained experimentally and found by numerical methods is carried out. Hardness values were measured for composites with different component compositions. An increase in hardness with an increase in the amount of a metal component is shown.
