I'm a former nuclear engineer so I feel *somewhat* comfortable with this topic, and I don't see anything particularly controversial here.

(Linear no-threshold and all that jazz ... we can sidestep those debates).

Where I do sympathise with the general public is that radiation operates entirely outside of the human sensory apparatus, and so there is no inbuilt, instinctive 'feel' for the danger level. It's not irrational to be ... irrationally fearful of it, if you see what I mean :)
