I seriously doubt if the radiation perv scanner doesn’t get people to do anything

You mean the backscatter X-ray units that have already been phased out 10 years ago?

The modern milimeter-wave scanners both do not reveal anything and do not use ionising radiation. If radiation is a concern to you, you really shouldn’t be flying at all to be honest. The dose you get up there is much higher than you’d get from an X-ray scanner, although it is still negligible.
