Introduction and background of TSA full body scanners

Full body scanners are an advanced security technology used to detect any suspicious belongings on a person's physical body. They are widely used in airports. One airport security precaution occurs when you place your handheld belongings on a conveyor and airport officials survey them. Airports will also have passengers step through a metal detector, however, as the name implies, these only detect metal. These full body scanners are able to detect metal and nonmetal items, which became a great security concern after the multiple airline bombing attempts throughout the 2000s. These scanners are able to produce "an alternate-wavelength image of the person's naked body, or merely a cartoon-like representation of the person with an indicator showing where any suspicious items were detected." They are quickly replacing metal detectors in airports and train stations throughout the country. Background Not all weapons come in metallic form. Terrorists will work their way around the security clearances of the US government and that means no metal. There are so many potential weapons that can slip undetected through metal detectors. Such items could be as simple as sharply carved items out of wood or hard plastic. The TSA (transportation security administration) thinks they have found a way to combat malevolent individuals who wish harm to flying passengers. The answer is in the new full body scanning technology that can detect even more potential threats than ever before.
