While TSA has the responsibility of trying to prevent potential terrorists from taking any type of weapon or explosives on to an airplane, it appears that a physical search of individuals may not be necessary. Green Dynamics has repeatedly pointed out that there are sufficiently technically and ethically acceptable options to detect all tagged and untagged explosives, including microscopic traces. The detection of PETN,which was allegedly used in the parcel bombs from Yemen, on people or in luggage and cargo is possible at a relatively low technical and financial cost.
In light of the recent problems with introduction full body scanners, specialists from 12 countries compared the advantages and disadvantages of explosives detectors and body scanners. They evaluated the body scanner as inappropriate for bomb detection. ” ‘Body scanners’ are not suitable for the detection of explosives and radioactive substances. A portable explosives detector is essential for the security check of passengers, luggage and cargo.”
The explosives detection experts refute the view that the explosive PETN is not detectable. There is technology from which detects and analyzes even the smallest traces of explosives and gunshot residue with a simple hand-held device.
