NEW YORK (WABC) -- Airports in New York and Los Angeles have become the latest equipped with body scanners that allow security screeners to peer beneath a passenger's clothing to detect concealed weapons.
The machines, which are about the size of a revolving door, use low-energy electromagnetic waves to produce a computerized image of a traveler's entire body.
Passengers step in and lift their arms. The scans only take a minute, and Transportation Security Administration officials say the procedure is less invasive than a physical frisk for knives, bombs or guns.
Someday, the "millimeter wave" scans might replace metal detectors, but for now they are being used selectively. | |
