Explosive Detection And Use Of Stimulant Explosives
Explosive detection is one important aspect of the security of any business establishment. Simulated explosives are used for testing the efficiency of these systems. Below are some of the aspects that related to explosive detection systems/devices and simulated explosives.
Services for security checkpoints
There are various screen training kits for checkpoints. These include the checkpoint training kits, the training kits for explosive recognition, training kits that are based on modular IED devices and more. Onsite explosive detection training solutions include the training for metal detectors, the image interpretation X-Ray, the HME/IED threats and the CSO court house training.
Availability of services
The explosive detection training kits and services are available to USA federal government security agencies and federal state agencies. The approved security services government contractors that hold due licenses and certifications can also avail these services and buy the products for providing enhanced security cover to any establishment.
Stimulants used for developing security systems and solutions
Threat objects including simulated explosives provide for better research and development that is the key to developing better security devices and explosive detection techniques and methods. Apart from these, simulated explosives also provide for better testing and better personnel training.
During the testing of automated and otherwise detection systems that are used for detecting explosives, live explosives have vast usage. They provide for better judgment on the effectively of the system and such system can be better developed and gains certification as well. The deployment life cycle of the product system requires further testing and training of the system.
Companies like DSA Detection provide a wide range of devices for detecting explosives in security wise, sensitive establishments such as airports, parks, train station, etc. to government agencies. Other companies provide simulated explosives for testing of such systems. Different kinds of explosive detection systems use different techniques and substances for detecting explosives. Simulated explosives are made after gaining detailed knowledge of the different kinds of properties that different explosives have. Such simulated explosives are safer, more inert and mimic the properties of the real explosives almost completely.
After the simulated explosives are fully developed, they are packaged for testing in different kinds of concealed and open scenarios and are used by both government and private agencies for detecting the efficiency of their explosive detection systems. They are also used to test the perfection of vigilance provided by the security personnel.
Changing threats
The threats have always been changing. During the decades of the 60s and 70s, the most profound test of civil aviation was in threats related to hijacking of airplanes. The threat of the concealed weapons that were used for hijacking the airplanes and terrorizing the passengers and staff was removed by the installation of x-ray scanners and metal detectors at airports. Later the threat of explosives emerged which was controlled by the checkpoint screening products detection systems which were fully automated and were used for checking baggage.

Most Widely Used Methods For Detection Of Explosives
Inspection of containers, bags, purses, etc. is done in order to find out whether they have explosive material or not at places that are more prone to terror threats. Hence, the devices and methods for explosive detection are frequently used at ports, airports, in bordering areas and in other sensitive locations.
Explosive Detection Systems
Below are listed some of the most widely used systems and methods that are used for detecting explosives.
Automated Detection Cliometrics
This is one of oldest and most widely methods for detecting explosive substances. A chemical agent is applied by the user to the materials which are suspected to have explosives. Color reaction provides for detection. The method can be used to detect both traces and high amounts of explosive materials.
Trained Dogs
Dogs are trained by police, military and other security agency personal. These dogs have better sensitivity to certain smells that associate with explosives. If the dog gets bored or tired of the process, the effectively is reduced.
Scent Detection by Machines
Machines for explosive detection can deduce the signature traces of the explosive. One such machine is Ion Mobility Spectrometry. In this machine, the molecules are first ionized and then they are run at atmospheric pressure. Larger time for ion movement indicates that the ion is colliding with other gas molecules that may be from the inner hidden explosives.
Gas Chromatography
Machines are combined with gas chromatography so that molecules can be better separated for detecting explosives. By adding gas chromatography, the detector’s performance and accuracy can be increased manifold. The user also gets one another data dimension.
X-Ray Machine
X Ray machines also provide for detection of explosives by analyzing the density of materials that are being examined. The X ray machine used for explosive detection differs from those X ray machines that are used for studying human images by doctors and physicians. The explosive detection X Ray machines have color coding and threat library, dedicated software and a system that is based on computerized axial tomography. Many airports, train and bus stations and other locations that have sensitive security aspects employ these machines as checkpoint screening products.
Neutron Activation Machines
These machines detect explosives by bombarding the suspect materials with atomic neutrons. They then try to determine what the chemical composition of the sample is by reading the signals that are given by gamma radiations.
