Abstract

El invento descrito en este documento proporciona un método y un aparato para localizar Artefactos Explosivos Improvisados (AEI) enterrados bajo la superficie del suelo. El aparato usa una fuente radiactiva emisora de neutrones rápidos y dos detectores de neutrones lentos. Puesto que los materiales usados en la actualidad para la manufactura de AEIs son esencialmente de bajo número atómico, también presentes en el suelo, generalmente en concentraciones diferentes a aquellas de los AEIs, cuando un volumen de suelo es examinado por neutrones rápidos, la detección de una variación local en la intensidad de la señal de neutrones lentos es indicativo de la posible presencia de material explosivo. El método incluye procedimientos de análisis numérico y de comparación con bases de datos previamente construidas que permitirán: (i) Determinar con suficiente precisión la posición del material explosivo sobre un plano paralelo a la superficie del suelo. (ii) Obtener una valoración estadística de la probabilidad de que el objeto localizado sea un AEI.The invention described herein provides a method and apparatus for locating Improvised Explosive Devices (IEDs) buried under the surface of the ground. The apparatus uses a fast neutron emitting radioactive source and two slow neutron detectors. Since the materials used today for the manufacture of AEIs are essentially low atomic numbers, also present in the soil, generally in concentrations different from those of AEIs, when a volume of soil is examined for fast 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 procedures for numerical analysis and comparison with previously constructed databases that will allow: (i) To determine with sufficient precision the position of the explosive material on a plane parallel to the ground surface. (ii) Obtain a statistical assessment of the probability that the object located is an AEI.
