Full-body scanners at airports replaced with less-revealing, low radiation machines

Airports across the U.S. have removed the full-body scanners that used x-rays to create what looks like nude images of passengers.

The remaining 250 machines were removed about two weeks before the June 1st deadline set by Congress.

Some critics said they were too revealing, while others expressed health concerns over radiation exposure.

Passengers still have to undergo full-body scans. However, the scanners now use radio waves that produce a less-detailed image.
