METHOD OF CONTROLLED OBJECT ANALYSIS FOR EXPLOSIVES Russian patent published in 2009 - IPC G01N23/222 G01N24/08 

FIELD: physics; measurement.

SUBSTANCE: application: for controlled object analysis for explosives. Substance: consists that controlled object is exposed to electromagnetic radiation invoking nuclear quadrupole atom resonance of at least one chemical element of explosive. Electromagnetic radiation emitted by controlled object is recorded, transformed to electric signal. Received effective electric signal is compared to related threshold value. If received effective electric signal exceeds related threshold value, the first plausibility ratio logarithm is defined for received effective electric signal. Thereafter controlled object is exposed to X-raying with X-ray imaging of controlled object. X-ray image helps to identify products of controlled object. Controlled object is exposed to thermal neutrons. Gamma-ray detectors record gamma-ray photons emitted by controlled object. Number of recorded gamma-ray photons is counted. That is followed by the second plausibility ratio logarithm definition for counted number of recorded gamma-ray photons. Then controlled object is considered to contain explosive, if total the first and second ratio logarithms exceed related threshold value.

EFFECT: higher probability of explosive detection and control speed.
