Some US Airports had backscatter x-ray scanners used by the TSA with their shiny badges who certainly had no training on x-ray safety. https://www.dailymail.co

  > ProPublic reports that researchers have estimated that widespread use of backscatter x-rays will cause between 6 and 100 cases of cancer each year among fliers. > The TSA maintains the devices are within federal safety limits. I've always "opted out" of backscatter machines. In about half the cases airport staff were exasperated with me. In Australia they interrogated me for "the specific reason" I requested a manual pat-down instead. I made one up. But my real reason was that I fly a lot and I don't need to be blasted with millimeter wave x-rays for no good reason.

    "Millimeter Wave" machines are NOT "backscatter x-ray" machines. Millimeter Wave is a radio-wave device.

    I've only ever seen mmWave full body scanners, TSA began phasing out backscatter X-rays in 2012 [1] and according to this [2] backscatter X-ray is no longer used in US airports. Maybe different in other countries, I don't know. mmWave is radio frequency not X-ray and similar frequencies are used in 5G.
