Automatized facility for express gamma-spectrometric studies of full-size core and muds of oil-gas wells

In the automatized facility 'Sputnik-Geo' for automated core feeding of the conveyor belt with 5 m length is using. Activity measurement has being conducted by four scintillation gamma radiation detectors. Symmetrical location of the detectors relatively the core allows to exclude of the geometrical uncertainty of component. The spectrum processing and the control by conveyor engine are carried out by computer, which preserves the results of measurements in the database. For density measurement the scintillation detector with collimated source on the 137Cs radionuclide base is applied. The facility is provided with the light-diode coefficient stabilization of detector amplification, that permits to operation time increase without spectrometers requalification by energy up to 1 working day
