Yeah, I thought about nuclear risk, but Hiroshima and Nagasaki seem like good enough evidence for the possibility of widespread annihilation (or even Trinity for that matter). This would only be a good example if there was widespread appreciation for GCR potential from nuclear risk before any nuclear detonations. I don’t think there was? (Especially considering that there was only a few short years (1933 − 1945) from theory to practice with the nuclear chain reaction.)
