Title:
DEVICE FOR LOCATING IMPROVISED EXPLOSIVE DEVICES BY MEANS OF THE BACKSCATTERING OF THERMAL NEUTRONS
Document Type and Number:
WIPO Patent Application WO/2022/243938
Kind Code:
A1
Abstract:
The invention relates to a method and apparatus for locating Improvised Explosive Devices (IEDs) buried below the ground surface. The apparatus employs one rapid neutron-emitting radioactive source and two slow neutron detectors. As the materials currently used in the manufacture of IEDs are essentially of a low atomic number, also present in the ground, but generally in concentrations different from those of the IEDs, when a volume of ground is examined by rapid neutrons, the detection of a local variation in the intensity of the slow neutron signal is indicative of the possible presence of explosive material. The method includes numerical analysis procedures and procedures for comparison with previously constructed databases, which enable: (i) The determination, with sufficient accuracy, of the position of the explosive material on a plane parallel to the ground surface. (ii) The obtaining of a statistical assessment of the probability that the object located is an IED.
