FIELD: chemistry.
SUBSTANCE: device for extracting radionuclides from aqueous solutions comprises a chamber-column filled with a selective sorbent fixed with disc screens on both sides. The chamber-column is additionally provided with a lid to fix the device for extracting radionuclides from aqueous solutions in vessels with aqueous solution, the lid has one or more holes and is adjacent to one of the disc screens, while the disc screen serves as an outer baffle of the chamber-column.
EFFECT: high efficiency of radionuclides' extraction from aqueous solutions, high measurement convenience and efficiency of the resulting radionuclide concentrate activity.
