DEVICE FOR DETECTING EXPLOSIVE SUBSTANCE IN CONTROLLED OBJECT Russian patent published in 2006 - IPC G01N23/222 

FIELD: technology for detecting explosive substance in a controlled object.

SUBSTANCE: device contains x-ray apparatus and apparatus for neutron-radiation analysis, including body with radiation protection, horizontal well made in body and radiation protection with one input aperture and chamber, formed by neutron reflectors in form of plates mounted in horizontal well, while upper and lower neutron reflectors are made of two immoveable elements and one moveable element positioned between them, equipped with motor and mounted with possible movement relatively to immoveable elements in horizontal direction, perpendicular to longitudinal axis of horizontal well. Also, device contains block for detecting gamma-radiation, positioned in the hollow of radiation protection oppositely to chamber behind neutron reflector, in form of at lest two gamma-radiation detectors, provided with collimators and mounted on moveable elements of upper and lower neutron reflectors on the side which is external relatively to chamber.

EFFECT: decreased probabilities of omission and false alarm when detecting an explosive substance, decreased value of minimal mass of explosive substance, which it is possible to detect by means of subject device for detecting explosive substance in controlled object, and also decreased dimensions and mass of apparatus for neutron-radiation analysis, included in composition of device.
