RADIATION-SHIELDING PROPERTIES OF POLYMER COMPOSITE MATERIALS
AbstractRadiation-protective properties of composition materials were investigated. Polystyrene, which was reinforced by an aluminum, was used as basic material. Also, tungsten powder was used as filling material. The composite was made in the form of spheres of 1-5 mm diameter. This allows to develop effective individual protection against gamma radiation without restricting mobility. The Monte Carlo method was used to investigate the energy dependence of the radiation-shielding characteristics of composite materials. We calculated relative attenuation of the absorbed dose of gamma rays for the protective layer with a different component mass composition and thickness of 10 mm.
