FIELD: protective devices.
SUBSTANCE: invention relates to the field of radiation protection of objects. Ionizing radiation protective screen for the on-board equipment complex is a two-layer structure placed on the outer surface of the instrument frame located in the instrument compartment. Outer layer is a material absorbing fast and thermal neutrons based on polyethylene with amorphous boron additives. Inner layer is an absorbing x-ray and γ-radiation of the material with a matrix based on rubber and with powdered fillers, such as tungsten and/or bismuth oxide, the thickness of the two-layer structure being at least 1 cm.
EFFECT: invention makes it possible to weaken the penetrating neutron effect on the onboard equipment complex (OEC), to absorb ionizing radiation due to the synergistic effect.
