an airport security system is a comprehensive system of checks and procedures designed to ensure the safety of passengers and staff at airports. it includes metal detectors, x-ray machines, and body scanners, as well as baggage and other security checks. all passengers and staff must pass through metal detectors, and the bags are screened by x-ray machines. body scanners are also used to detect items that may not be visible to the x-rays, such as metal weapons or explosives. finally, all bags must be checked against a list of prohibited items and any suspicious items must be examined by security staff.
