I dunno. I think we're pretty safe. Chernobyl upchucked a whole bunch of radiation into the atmosphere and scientists never said we were in any serious danger from it.
Well, it's been awhile, but I distinctly remember the fallout basically blanketing Scandinavia with some residual over central Europe. As I was in Germany when Chernobyl blew up in 1986, there were some worried folks, especially pregnant women.
AFAIK, I don't have 19 forms of cancer, so I probably dodged a bullet.
