A new screening device capable of detecting explosive material that metal detectors cannot will be introduced for passengers boarding international flights at 29 airports, including Haneda and Narita airports, starting in October.
The system’s alarm goes off when a certain probability of such material being present is reached. The measure is being taken to check for suspicious objects, in accordance with international antiterrorism standards.
Currently, passengers are required to pass through a full-body metal detector before boarding. When the alarm goes off, a security officer frisks the passenger. However, the new scanner’s alarm may go off even if a passenger is not carrying metal objects.
The International Civil Aviation Organization requires its member countries to introduce either a full-body scanner that sees through the whole body or a random bodily check. The new system has already been introduced at airports of other Asian countries.
