FIELD: technological processes.
SUBSTANCE: submersible gamma-absorption probe contains casing submerged into device with cavity for passage of analysed liquid, source and scintillation detector of gamma-radiation, which are installed opposite to each other, screen with collimating opening, at that screen is installed outside the casing and represents cover of device chasm with collimating openings for casing passage, at that detector is made as gamma-spectrometric, and spectrum processing device is introduced.
EFFECT: increase of probe application area by provision of operability in expanded range on intensity of exposition dose of controlled medium gamma-radiation.
