What happens in an atom bomb explosion?
Unlike an atomic power plant, where a chain reaction for splitting uranium is allowed to run in a controlled way, in an atomic bomb it runs at high temperature over 10million °C. This is the strong heating create an immense pressure wave. The pressure and the heat wave destroy everything in its surrounding. Tens of thousands of people were killed immediately when two American atom bombs were thrown on Hiroshima and Nagasaki on August 6 and August 9,1945, respectively. The infamous 'mushroom cloud' rose up to height of 13km and about 20 minutes later radioactive rain fell from this cloud to two cities. A number of people have died or have developed abnormalities which consequences of the radioactivity caused during explosion.
