Here’s a searchable guide to body scanners in U.S. airports. X-ray "backscatter" machines have faced concerns about the potential health risks associated with them.

Find out whether you may encounter an X-ray scanner this holiday season by entering your address, airport code, city or ZIP code below. If your airport doesn't come up, it doesn't use either type of body scanner.
