Millimeter wave scanners are of an entirely different kind of 'radiation' than backscatter X-rays in the same way 'red light' is of a different kind of radiation from 'alpha particles'. Yes, technically they are are the "radiation" of an emitted particle from an interaction. But they are of significantly, quantitatively, and oncogenically different kinds of 'radiation'. Backscatter X-ray radiation is of very high intensity and almost certainly can cause damage to biological surface tissue. Millimeter wave uses non-ionizing radiation - it does not have the capability of causing what we generally refer to when we speak of biological damage by radiation. It might do something else - though this seems to be debatable, and largely hypothetical, it is simply incapable of the damage that a backscatter X-ray machine could realistically cause. Here's the letter authored by significant scientists written to the White House in regards to their thoughts on the backscatter machines [1].
