Stainless steel is one of the most common materials used in everyday products, but can it set off an airport metal detector? The answer is yes. Although stainless steel is generally non-magnetic, it still contains trace amounts of iron, nickel and other metals which can be detected by metal detectors.
Common metals that will set off an airport metal detector include iron, steel, nickel, copper, brass, aluminum, and titanium. Other metals, such as gold and silver, will not typically set off a metal detector, but they may be detected by X-ray or other security screening methods.
If you are directed to go through a metal detector, let the security personnel agent know that you have an implanted medical device that might set off the alarm. If you are directed to the full body scanner, there are no special precautions you need to take.
“Millimeter wave imaging technology does not detect items inside a passenger's body or penetrate the skin,” Langston says. That said, Malvini Redden says body scanners would also not pick up anything else stashed inside a body cavity, such as drugs or hazardous liquids.
You may be required to undergo a pat-down procedure if the screening technology alarms, as part of unpredictable security measures, for enhanced screening, or as an alternative to other types of screening, such as advanced imaging technology screening.
Baggy clothing can include low-hanging pants, flowy skirts, heavy sweaters or sweatshirts, and loose dresses – things that would allow malicious travelers to hide prohibited items. Airport security may need to do a pat-down inspection if your clothes are too loose and they suspect you may be hiding prohibited items.
Airport body scannersalert the TSO to threats—mainly weapons such as knives, guns and explosives. They are designed to detect “metallic and nonmetallic threat items,” according to the TSA. Those are things like explosives or knives made out of materials other than metal, like ceramics, says Malvini Redden.
