What happens if the metal detector goes off in the airport?
In the United States, the TSA will have to give the passenger a secondary screening if the alarm goes off. This is when an officer pats you down and uses a handheld detector. A secondary screening should only take a couple of minutes at most.

If you set off an alarm on the metal detector gate, a security officer will determine why this has happened. You will be asked to remove any items that may have caused the alarm and then walk through the metal detector again. The staff may also conduct a pat down search.
The sensitivity of metal detectors is based on a scale of 1 to 15 (1 being the least sensitive, 15 being the most sensitive), and the average airport detector is set at five. Some detectors, particularly in high-risk security areas of the world, are set at seven.
One of the most common reasons you will get a pat down is if you refuse to go through the walk-through metal detector or the full body scanner. For some people going through a metal detector is not an option, while others just may prefer to not go through these.
TSA officers use the back of the hands for pat-downs over sensitive areas of the body. In limited cases, additional screening involving a sensitive area pat-down with the front of the hand may be needed to determine that a threat does not exist. You will receive a pat-down by an officer of the same gender.
Can I wear an underwire bra to an airport? Yes you can wear an underwire bra. Depending on TSA standards in scanning, a metal detector may be sensitive enough to pick-up the bra. This may lead to you being wand.
Can you see a tampon during an airport body scan? This is a frequently asked question on Google, and if it's something you're worried about, you can breathe a sigh of relief. Airport body scanners can't see inside the body and therefore can't detect a tampon on a TSA female body scan image.
Furthermore, the GAO report found that it isn't just headgear and hairstyles that increases the rate of false alarms, a passenger's body fat content will also affect the rate of false alarms.
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.
Metal detectors can detect both ferrous and non-ferrous metal types, although they detect ferrous metals more easily due to their magnetic properties. Ferrous metal contains iron and is often magnetic, while non-ferrous metal consists of other elements like nickel, aluminum, and zinc.
All Standard Pat-down searches must be conducted by a TSO of the same gender. An individual's gender is what he or she purports himself or herself to be.
It all depends on the country and the airport. Some metal detectors and scanners are set to give a false positive signal at random intervals, leading to a personal search, but in many instances what are declared to be random searches are not that at all.
