FIELD: chemistry.
SUBSTANCE: invention relates to spectrometers for detecting xenon radionuclides. Spectrometer for detecting volumetric activity of xenon radionuclides, in which measured sample represents mixture of gases, contains detecting part, made with possibility of detecting beta-radiation and gamma-radiation and which contains measuring chamber, beta-radiation detecting unit and gamma-radiation detecting unit, with beta-radiation detecting unit containing at least two beta-radiation detectors and gamma-radiation detecting at least one gamma-radiation detector.
EFFECT: increase of detection efficiency, reduction of detection time.
