Why does my body set off TSA scanner?

Airport scanners can efficiently detect hidden illegal items but cannot see inside the body. If you set off the scanner during the screening process, you might be causing false alarms due to piercing, body jewelry, implants, or medical devices on you like pacemakers, braces, pant zip, watch, or even hairpins.

Metal detectors create a magnetic field by using a brief pulse of electrical current. The magnetic field will be reflected back to the machine if there are any metal objects present, such as a watch or a belt buckle. The return signal is detected by the machine and a beeping noise is produced to alert the TSA agent.

The backscatter x-ray scanners expose individuals to 0.03–0.1 µSv per scan 7–10 or the equivalent to 3–9 minutes of radiation received from naturally occurring sources as part of daily living. Thus, the exposure from the scans is relatively small.

Depending on the type of machine, ionizing radiation is used to identify objects that may be hidden by passengers and to create images of what is in luggage. Backscatter passenger scanners are used to detect threats such as weapons or explosives that a person could be carrying under their clothing.
