PORTABLE DEVICE FOR IDENTIFYING HIDDEN SUBSTANCES (VARIANTS) Russian patent published in 2012 - IPC G01N23/222 

FIELD: scanning devices.

SUBSTANCE: invention is used to detect hidden substances with radiation methods. The γ-radiation detector is made on the base of LaBr₃ crystal, the laser generators of the line are installed with the possibility to set a flux of monochromatic neutrons on the inspected object, the spectroscopic channel of the γ-radiation detector is fitted with a thermal correction system comprising a thermal sensor fixed on the LaBr₃ crystal, in thermal contact with it, an amplitude-to-digital converter (ADC) and a single-board minicomputer. Furthermore, the thermal sensor is connected through a communication line and a supply line with the ADC, which is connected through a system bus to the single-board minicomputer, connected with the power source and the control unit.

EFFECT: the maximum possible registered distinctive gamma-radiation intensity is achieved; increased gamma-detector sensitivity; reduced the amount of errors caused by the lack of ambient temperature compensation; increased targeting accuracy and the radiation area of the inspected object; allowed the detection of smaller amount of dangerous hidden substances.
