Screening Technology

TSA uses millimeter wave advanced imaging technology and walk-through metal detectors to screen passengers. Millimeter wave advanced imaging technology safely screens passengers without physical contact for metallic and non-metallic threats, including weapons and explosives, which may be concealed under clothing. Passengers have the option to request a pat-down as an alternative. See the responses to frequently asked questions.

Safety: Advanced imaging technology is safe and meets national health and safety standards. This technology uses non-ionizing radio-frequency energy in the millimeter spectrum with no known adverse health effects. It does not use X-ray technology.

Privacy: TSA has strict privacy standards when using advanced imaging technology to protect your privacy. Advanced imaging technology uses automated target recognition software that eliminates passenger-specific images and instead auto-detects potential threats by indicating their location on a generic outline of a person. The generic outline is identical for all passengers.
