Airport security scanners, also known as airport security screening machines, are devices used to detect potential threats in luggage and on passengers at airport security checkpoints. These machines use a variety of technologies, including X-rays, millimeter wave technology, and backscatter technology, to scan passengers and their belongings for weapons, explosives, and other prohibited items. X-ray scanners use low levels of radiation to create images of the contents of a passenger's luggage. Millimeter wave technology uses radio waves to create a three-dimensional image of a passenger's body, while backscatter technology uses low-level X-rays to create a two-dimensional image of a passenger's body. Both millimeter wave and backscatter technology are designed to detect hidden objects on a passenger's body, such as weapons or explosives. While airport security scanners are an important tool in keeping air travel safe, there are concerns about the potential health risks associated with exposure to radiation from X-ray scanners. To address these concerns, some airports have begun to use millimeter wave and backscatter technology instead of X-ray scanners. Despite these concerns, airport security scanners remain an essential part of airport security. They are used to screen millions of passengers every day and have helped to prevent numerous potential threats from being brought onto airplanes.
