The TSA phased out all the X-ray backscatter machines due to radiation concerns. All the scanners at airports use millimeter wave radar now. Still the same privacy concerns, but no ionizing radiation and thus no possible health concerns.

WRONG.

Such machines are still in use and besides, neither machine machine has provably been better than plain old metal detectors.

Was this CNN article wrong then? I don't travel very much, but haven't seen an X-Ray backscatter machine since last year.
