I am surprised by the number of comments to this answer. . The blast of a nuclear explosion also drives air away from the site of the explosion, creating sudden changes in air pressure that can crush objects and knock down buildings. Planning ahead, sheltering in place, and protecting yourself when you do need to go out can increase the odds of coming out of the other side in one piece. Note that the atomic cloud after the explosion is said to have reached a height of 70,000 feet (about 21 km). Putin promises 'immediate' reaction if Russia threatened. In the simulator description, Wellerstein said the aim of the educational tool was to help people visualize the impact of nuclear weapons in simple terms in order to help them gain an understanding of the scale of these blasts. The dangerous fallout zone can easily stretch 10 to 20 miles (15 to 30 kilometers) from the detonation depending on explosive yield and weather conditions. To be directly visible from 810 km distance it had to be exploded at the height How far can radiation travel in air? Thats where having a rural retreat is a good long-term solution. The prospects for survival are even better if there are several minutes of warning, something Hawaii's ballistic-missile-threat system can provide. @DavidRicherby: When reading the title of this question in the hot questions list, I at first assumed this was a question from.
