Do you have some links from scientists who have done such research?  No snark, I don't have an agenda (beyond thinking that the more renewable--from the sun [wind, solar, wave]--energy the better.)  Maybe she did have an agenda.  Well, yes, of course.

So let's say this clouded her judgement.  Maybe she should have visited more sites, not just nuclear.  (Though your point about chemical etc. plants would, I think, only add to her case--as far as I understand, it's genetic damage caused by industrial waste that bothers her, not just nuclear.)  

The thing is, one of her points was that other scientists weren't/aren't studying this, and she wanted to highlight the issue, so any links to where scientists have done the kind of comparative research you describe, would be much appreciated.
