Population studies outside Hiroshima and Nagasaki show that cancer rates are roughly the same as background levels, suggesting hormesis or radio-protection.

“when you look at the population studies that were done outside the blast at Hiroshima and Nagasaki when of course you the initial concentration everyone dies from the thermonuclear energy but as you get several miles out not only are the cancer rates actually roughly the same as the background you actually see again evidence of hormesis where you have some patients in whom or maybe not hormesis but some sort of radio protection where you actually have lower rates of leukemia and thyroid cancer when you get a few miles farther out than you did in the general population”
