You'd get about a 1 mSv dose, and be fine. I'm more worried about the 200,000 or so daily premature deaths due to fossil fuel pollution.

Go live in an airplane crash for a couple of months and then let's talk again about whether we should continue to operate them? Or is the exhaust of a coal plant -- oh wait, that's worldwide, you're already more likely to get all sorts of stuff from air pollution -- a better comparison? This line of reasoning makes no sense to me.
