Is radiation from airport scanners dangerous?

You’d need more than 22,500 scans to be in danger

You would need more than 22,500 scans from airport full-body scanners in a year to reach the US limit for safe doses of radiation, a new report finds.

The report, Radiation Dose from Airport Scanners, commissioned by the American Association of Physicists in Medicine, says that full-body scanners give a radiation dose equivalent to what most people get every 1.8 minutes on the ground, or every 12 seconds during a typical flight.

“This report represents a wholly independent review of the X-ray scatter airport scanners and is the first we know of to look at multiple scanners including those in actual airport use,” said one of the report’s lead authors, Christopher Cagnon, PhD, DABR, who is chief of radiology physics at the UCLA Medical Center.

“We think the most important single take-away point for concerned passengers is to keep an appropriate perspective: the effective radiation dose received by a passenger during screening is comparable to what that same passenger will receive in 12 seconds during the flight itself or from two minutes of natural radiation exposure.”
