Is 5G tech at the same Millimeter waves frequencies as those used in airport scanners? I've heard mm scanners as considerably safer than the old backscatter x-r

Is 5G tech at the same Millimeter waves frequencies as those used in airport scanners? I've heard mm scanners as considerably safer than the old backscatter x-rays (although full of false positives and no better than random chance at actually detecting things).

Yes, sort of. Backscatter X-ray is ionizing (much smaller than mm - about 0.0000001 millimeters, so something like EHz - ExaHertz). While 5G new radio is 60 GHz (5 mm), like WiMax supposed to be. Airport mm-wave machines are somewhere around 24-30 GHz (so around 10mm). (source: https://ec.europa.eu/health/scientific_committees/opinions_layman/security-scanners/en/l-3/3-technology.htm https://ec.europa.eu/health/scientific_committees/opinions_l... ) So far concerns are about insects (heating) and bacterium (antibiotic resistance "could" develop - https://news.ycombinator.com/item?id=21261425 https://news.ycombinator.com/item?id=21261425 ). Though the heating effect is probably negligible compared to how cities already radiate a lot more heat and insects are loving it. Furthermore, if there is any serious new/strange/second-order effect on biology we would have already seen it, as people blasted lab animals with every kinds of EMF and we got only the coincidental expected flukes.
