DEVICE TO DETECT AND IDENTIFY HIDDEN HAZARDOUS SUBSTANCES UNDER WATER Russian patent published in 2014 - IPC G01N23/222 

FIELD: measurement equipment.

SUBSTANCE: device for detection and identification of hidden hazardous substances under water comprises a source of marked monochromatic neutrons and their associated monochromatic α-particles, a detector of α-particles, a detector of γ-radiation with a protection from a flow of marked monochromatic neutrons. At the same time the working module is placed in a tight polymer container for underwater works, made as capable of vacuumising, equipped with appropriate water-impermeable slots for supply of Ethernet cables and power supply, to a wall of a tight body of the container in direction of the flow of marked monochromatic neutrons a water impermeable nozzle is fixed with the help of a flange, the axis of the nozzle matches with the direction of the central bundle of marked monochromatic neutrons. At the same time the nozzle is made in the form of bellows with capability of longitudinal deformations, and the size of its cross section is selected based on the condition of passage of the entire flow of marked monochromatic neutrons; the container for underwater works is equipped with supports, and also with a system for its flooding.

EFFECT: provision of the possibility to detect hazardous substances with higher probability, provision of the possibility to eliminate contact of a device with an object of examination.
