If more people are likely to die per year from cancer caused by the scanners than are likely to die from terrorists, I think that's a convincing argument that using the scanners screen passengers is worse than not screening them at all.

Sure, that's true (given your assumptions) if the scanners pose any risk that's worse than just walking a distance equivalent to the space taken up by the checkpoint. But as I said, that's not the question under discussion; the question is whether there is any significant difference between one type of scanner and another, given that you're going to scan passengers.
