FIELD: building, particularly pneumatic building structures for nuclear engineering and medical technology for gamma-ray, X- and neutron radiation protection and to attenuate above radiation. ^ SUBSTANCE: to attenuate neutron radiation emitted by object, which is located under pneumatic structure, the polyethylene material is suspended to film-and-fabric warmth-keeping jacket with the use of continuous movable threads. The threads pass through rings. Pressure shell, film-and-fabric warmth-keeping jacket and polyethylene material are spaced apart and spaces defined by them are filled with air. Film-and-fabric warmth-keeping jacket and polyethylene material are provided with through orifices for air passage. Space between film-and-fabric warmth-keeping jacket and polyethylene material may vary to meet necessary operational requirements. ^ EFFECT: increased efficiency of neutron radiation attenuation due to increased hydrogen content in polyethylene material. ^ 2 dwg |
