>that fallout isn't going any where any time soon. It becomes exponentially less radioactive due to decay. The long-lived isotopes that persist might eventually give you cancer or cataracts, but the short-lived isotopes present in the immediate aftermath of a blast will kill you. The dose makes the poison and fallout shelters vastly reduce the absorbed dose of radioactivity.
