What is the detection of explosives?

Explosives are devices designed to change the environment in the construction process, or cause damage and loss of life by sudden expansion of gases by force, heat and noise due to a reaction that can be chemical or nuclear. Explosives are divided into high explosives and low explosives - which are divided into explosives of power, atomic and fuel and air explosives. The transport of explosives is regulated in many countries, such as the regulatory division of explosives in Canada, Canada and the Office for Alcohol, Tobacco, Firearms and Explosives - as well as state law - in the United States. Trace explosive detection (ETD) is a technology designed to detect the smallest quantities or traces of explosives for safety and security.

Explosive tracking detection has been developed in various formats. There are handmade modules, portals for screening people and desktop models. Explosive detection are usedAlso technology of explosives based on explosives. Some types include the spectroscopy of mobility mobility (IMS), chemiluminescence (CL), electrone detectors (ECD) and surface acoustic wave (SAW). For fields, the use of mass spectrometry (MS), long used in laboratory environments.

There are a number of circumstances in which detection of explosives is used. It is employed at airports to screen passengers and luggage and postal facilities to detect the safety of doubtful packages. Teams for bombs and teams to build security teams in high -risk devices use ETD. For an army in the field, portable explosives detection devices are used to detect threats such as liquid and plastic explosives and other components that find the way to improvised explosive devices (IED).

Concerns when using explosives of detection devices include false negative speeds and falsePositive rates. The detection limit (DL), the level of the smallest detectable amount of material that can be identified is also a matter. Processing time can also be a problem in an unstable situation and developers are working on this matter. Some devices promise to analyze all explosives varieties in 30 seconds or less.
