FIELD: physics, nuclear physics.
SUBSTANCE: invention relates to nuclear reprocessing of immobilisation of volatile forms of radioactive and stable isotopes from gas-aerosol flow from the unit of felling - dilution of processed fuel. The sorbent comprises a porous, permeable, inorganic base, made permeable by a labyrinth macrostructure, whose cross connections are made from a material with modified components of nanostructure sizes identical in composition to the basic material, and the surface of the porous space is covered with a nanoporous layer of an active agent.
EFFECT: improved quality, widening of the field of use of the sorbent and base materials for making it.
