Explosive Ordnance Reconnaissance
Explosive ordnance reconnaissance – reconnaissance involving the investigation, detection, location, marking, identification and reporting of suspected unexploded explosive ordnance, in order to determine further action.
Explosive detection is commonly used at airports, ports, and border control. The use of colorimetric test kits for explosive detection is one of the most established, simplest, and widely used methods for detecting explosives. Colorimetric detection of explosives involves applying a chemical reagent to an unknown material or sample and observing a color reaction. Common color reactions are known and indicate to the user if an explosive material is present and, in many cases, the group of explosives from which the material is derived. The major groups of explosives are nitroaromatic, nitrate ester, nitramine, and inorganic nitrate-based explosives. Other groups include chlorates and peroxides, which are not nitro-based explosives. Since explosives usually contain nitrogen, detection often is based around spotting nitrogenous compounds. As a result, traditional colorimetric tests have a disadvantage: some explosive compounds (such as acetone peroxide) do not contain nitrogen and are, therefore, harder to detect. Explosives detection conventionally focuses only on performing class-based discrimination: namely, providing the ability to distinguish between prohibited (e.g., explosives, precursors, flammables, oxidizers, etc.) and benign materials. For example, the fact that flammable liquids tend to have larger molecules (and, therefore, larger intermolecular spacings) than water-like substances allows one to characterize the flammability of a liquid by determining where its dominant XRD peak occurs [ScienceDirect Topics].
