link to these studies?
backscatter machines are considered complete safe, from what I understand. they use radio waves (not ionizing radiation) the same as phones/microwaves, and the waves don't even penetrate skin (or else they wouldn't be very effective, would they)?
you have nothing to worry about, medically, from them. I guarantee you're being bombarded right this moment with a similar amount of energy in a similar portion of the spectrum from Wifi, phone calls, bluetooth, FM/AM radio, GPS radio, etc.
- TeMPOraL 9y agoI think GP is referring to these: https://en.wikipedia.org/wiki/Backscatter_X-ray https://en.wikipedia.org/wiki/Backscatter_X-ray whereas you're thinking of these: https://en.wikipedia.org/wiki/Millimeter_wave_scanner https://en.wikipedia.org/wiki/Millimeter_wave_scanner. They are compating technoogies; the former employ ionizing radiation, the latter do not. I don't really know which ones are employed on US airports right now, but backscatter X-rays were employed at some point, which generated a bit of media shitstorm few years back.
- 2bitencryption 9y agoAh, yes, my mistake. I was aware the TSA used X-ray machines at some point, but I thought those were phased out long ago. I absolutely would refuse to get into one of those.
