abstract:A full-body scanner is a device that detects objects on a person's body for security screening purposes, without physically removing clothes or making physical contact. Depending on the specific technology, the operator may see 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.
The home secretary responded that there would have been a 50-60% chance of detection with the full-body scanner, "given where the explosives were placed".
