No not at all. Plenty of people survived the Hiroshima bomb including some who were a relatively short distance away from the blast center. I recall reading that there was one one young girl only 300 meters or so from the blast who apparently was down in the family bomb shelter getting some veggies for the family (it doubled as a root cellar) when it hit. The blast pretty much sealed her in and that is what saved her. Much of the radiation has a pretty short half life and dies out within hours or days. Since she was underground and behind a bunch of rubble she couldn't get out and run around madly absorbing radiation like the other survivors. By the time they got her out a few days later much of the short term radiation had died down.Plymtom wrote:if say it's a 2 megaton nuke landing on Plymouth, the best bet may be for bunkerless me to go outside with my family and wait for the show
Ok it wasn't 2 megaton but the moral of the story is clear. Get underground or under cover and stay there for as long as you can after the blast. The most dangerous thing, which everybody of course wants to do, is attempting to leave the area immediately after the blast. People doing that will just get trapped in a sea of refugees and bake in the radioactive glow along with everybody else.
