FIELD: chemistry.
SUBSTANCE: composition for protection from the effects of ionizing radiation is made in the form of layers, each of which is a matrix of radiation-resistant polymeric material with a filler. The filler contains one or more chemical elements or their compounds. As the filler matrix, facing the source of primary radiation, boron compounds were used. The fillers of each successive layer are selected from the condition of increasing the effective atomic number of the chemical element of the filler material. The attenuation coefficient of each layer is 0.2-0.6.
EFFECT: invention allows to increase the coefficient of attenuation and to reduce the weight and size characteristics.
