FIELD: chemistry.
SUBSTANCE: invention relates to radio analytical chemistry and can be used to monitor content of radionuclides in fresh and sea water, in urine of individuals exposed to radiation and in samples of different process solutions. The method of extracting radionuclides from aqueous solutions includes filtering the solution through a selective sorbent placed in the drip chamber of an apparatus used for intravenous transfusion of infusion solutions and preparing an agent suitable for gamma-ray spectrometry.
EFFECT: faster method while maintaining high efficiency and reducing measurement errors and distortion of results due to absorption of the measured gamma-radiation by filters.
