The hell, now even Tokyo (Haneda) has backscatters. This I do not like.

Looks like millimeter wave rather than backscatter: propublica.org/special/scann… (though US has phased out backscatter by now, I think)

Wasn't aware that backscatter was phased out (haven't travelled to the states in a good while) - so this is "exposure" free?
