> Coal plants emit much more radiation than nuclear plants - even old ones. There's lots of research about HOW MUCH more radioactive coal power is, but we're talking about anywhere from 50-200% more.

I don't fully understand this argument: A well-maintained nuclear power plant emits next to no radioactivity (compared to the natural background), so a coal plant that emits even a huge factor more radioactivity is still negligible.

I feel like the absolute number (x times more radioactive than nuclear) is really not helpful, if one of the numbers is (just as an example) 0.0001% of natural background, and the other is 0.001% of it.
