Method for detecting explosive agent i.e. bomb, in buried object, involves charging buried object with fast neutrons from isotopic neutron source, and measuring gamma radiation coming from buried object by detector

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for detecting explosive agents, such as bombs, that are buried underground. The technique involves using an isotopic neutron source to emit fast neutrons towards a suspected buried object. The interaction between the neutrons and the object produces gamma radiation, which is then measured by a special detector, allowing identification of explosive substances within the object.

Use CasesContent extracted from patent full text and abstract with AI.

• Locating landmines or unexploded ordnance in former conflict zones
• Detecting buried improvised explosive devices (IEDs) in military operations
• Screening construction or excavation sites for hidden explosives
• Assisting security teams in event venues or public places to check for hidden threats
• Aiding forensic teams during investigation at crime scenes with suspected buried bombs

BenefitsContent extracted from patent full text and abstract with AI.

• Non-intrusive and does not require excavation to identify explosives
• Provides rapid and accurate detection of buried explosive materials
• Increases safety for personnel by reducing the risk of accidental detonation
• Can be adapted for use in various terrains and soil conditions
• Minimizes disruption to the environment compared to traditional detection methods

Patent Abstract

The method involves guiding an isotopic neutron source (4a) through ground (1) at a distance of 50 cm or less to a buried object (3). The buried object is charged with fast neutrons from the source, where the fast neutrons (5a) are selected with average energy between 1 megaelectron volt and 5 megaelectron volts. A detector (4b) is guided together with the source through the ground, where the source contains californium-252. Gamma radiation coming from the buried object is measured by the detector, which contains sodium iodide and bismuth-germanate. An independent claim is also included for a device for implementing a method for detecting an explosive agent in a buried object.
