FIELD: construction.
SUBSTANCE: invention is related to radiation protection of biological objects, namely to construction or finishing of residential and administrative-production premises, having complex heat insulation, heat accumulating, neutron-moderating and absorbing properties. Method for erection of construction element for protection of biological objects against neutron radiation by means of protective layer creation in construction element, for instance in building wall, having heat insulation and accumulating properties and high radiation protection. Protective layer is made of layerwise laid cylindrical reservoirs, for instances polyethylene bottles, filled by 85-90% of reservoir volume with concentrated water solution of salt. Besides space between reservoirs is filled with construction mortar, containing sand, cement and natural materials, for instance wastes of spent ore, slag, containing chemical elements with increased section of neutron capture at the following ratio of components, wt %: sand - 10-20, cement - 30-60, natural materials -10-15, water - the rest.
EFFECT: provision of protection against neutron radiation and improved ecological conditions.
