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 lightning speed and totally out of control. The explosion gives rise to temperature of over 10 million 'C. This strong heating crates an immense pressure wave. The pressure and the heat wave destroy everything in its surroundings.Ten of thousands of people were killed immediately when the 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 a height of 13 km and about 20 minutes later radioactive rain fell from this cloud on the two cities. A number of people have died or have developed abnormalities which are the consequences of the radioactivity caused during the explosion.
