BOSTON — The Transportation Security Administration on Friday announced nine more U.S. airports that will receive body-scanning technology, as the U.S. heightens its effort to detect hidden explosives and other weapons amid a threat highlighted by an attempted bombing on Christmas Day.
TSA security director Lee Kair said units will be fielded in the coming months at Fort Lauderdale, Fla.; San Jose, Calif.; Columbus, Ohio; San Diego; Charlotte, N.C.; Cincinnati; Los Angeles; Oakland, Calif.; and Kansas City.
They will join three machines going online Monday at Boston's Logan International Airport, and one being deployed next week at O'Hare International Airport in Chicago.
All are among 150 machines bought with money from the federal stimulus package signed by President Obama last year. They join 40 machines already in use at 19 airports nationwide.

Both the new and existing machines will also now be in a primary position, meaning they will be the default screening equipment passengers face at a checkpoint. The existing machines have been in a secondary position, being used only when a passenger failed a metal screening or posed some other risk factor.
Passengers retain the right to opt out of a body scanning for a more intense but traditional screening.
Deployment of the machines was announced in the fall, before the alleged plot to blow up a Detroit-bound airliner on Christmas Day. Even so, that event highlighted the need for additional security in the U.S. aviation system.
