Which of the following is NOT a screening method used at the airport?

The method that is not typically classified as a screening method used at the airport is personal interviews. Screening methods primarily focus on physical and technological processes that examine baggage and passengers for prohibited items, ensuring the safety of air travel.

Walk-through metal detectors are standard equipment that scans individuals for metallic objects that could pose security threats. X-ray equipment is extensively used to analyze the contents of bags and carry-ons, helping security personnel identify potentially hazardous items. Explosive detection systems are sophisticated technologies designed to identify explosives within luggage or on a person.

In contrast, personal interviews, while they may be part of the overall security process, are not a conventional screening method. They serve more as a security measure to gather information or assess the behavior and intent of passengers rather than to scan for prohibited items. This distinction highlights the focus of airport security on direct physical and technological screening rather than solely on behavioral assessment.
