When the atomic bombs were dropped over Hiroshima and Nagasaki, people receive two doses of radiation: one during the explosion, and another from fallout. Experts say that approximately 50% of humans exposed to 450 rems will die, and 800 rems will kill virtually anyone. Death is inevitable and will occur from between two days to a couple of weeks. The first dose in the explosion had much rem and killed everyone instantly, so much that some people just evaporated. The second dose killed people within weeks. We can calculate and estimate but no measurement would survive in the ground so we actually don't have the exact number.
