Note that exposure to UV from sunlight has benefits as well as costs (e.g., vitamin D production). I personally wouldn’t want to bet heavily that in the “interesting” range the effect is close to linear, nor that the linear term has the sign you think it has.
I am actually trying to just consider the effects via cancer risk in isolation, and ignoring the potential benefits (which I think do go beyond just Vitamin D… probably a lot of stuff happening that we don’t understand… certainly seems to have effect on mood, e.g.)
