Have you considered and planned for nuclear war? It's been nearly 80 years since two nuclear bombs were detonated over the Japanese cities of Hiroshima and Nagasaki, killing at least 129,000 people, and causing devastating, long-term health effects. What would be the immediate impact and how far would the radiation zone extend? The temperatures near the site of the bomb blast during the Hiroshima explosion were estimated to be 300,000 degrees Celsius (540,000 degrees Fahrenheit) - which is 300 times hotter than the temperature bodies are cremated at, so humans were almost instantly reduced to their most basic minerals. Green: Radiation (0.74-mile radius) Within at least 15 minutes of a blast, clouds of dust and sandlike radioactive particles what's referred to as nuclear fallout would reach the . Detonating nuclear weapons above ground sends radioactive materials as high as 50 miles into the atmosphere. He later told BBC Breakfast Putin wanted to remind people he had a deterrent: "We don't see or recognise in the sort of phrase or the status he described as anything that is a change to what they have currently as their nuclear posture. Do not reproduce without permission. The blast moves faster than the impulses in your nerves, so there's no time for any sensation to register before you're dissolved into a ball of superheated fire. The blast area of destruction is only 5-7 miles from any nuclear target, so don't prepare against blast effects, which is very expensiverelocate instead. plus there is 2 radiation map locations by where you look.
