I understand your point, and I understand that cancer can and will pop up in safe environments.

However, that much radioactivity cannot be good. I understand that those were mostly detonated in safe environnements and in safe ways, but that is a lot of detonations right there. I'm not sure I can trust that all of those denotations released nothing bad in the atmosphere.

I would be curious to overlay a map of cancer rates over a map of detonations, taking wind into account.
