The atomic bomb is the most powerful and most terrible weapon.
With all the atomic weapons in the world, its possible to destroy the world three times.
During the Second World War, the scientists found out, that its possible to win this war in one go, with the help of a bomb, that functions with nuclear power. It was a new challenge to build such a bomb for the engineers and physicists, because the nuclear power was just newly discovered.
From this time a big competition began between Germany and the United States to invent and build such a bomb.
Both nations knew, that the faster will win the war.
In summer 1945 the United States built and tested an atomic bomb as the first nation. But Germany was beaten earlier, so the Americans used their new weapon against the Japanese.
The atomic bomb has exist already over 50 years, but its fortunately only used twice. 1945, the Americans dropped an atomic bomb over the Japanese cities Hiroshima and Nagasaki. So an American aircraft flew over Hiroshima in the morning of August 6 1945, and dropped the 4 tons heaviness atomic bomb at the height of 10 kilometres. Before they dropped the bomb, when the aircraft flew to Hiroshima, they gave a short alarm in the city, but otherwise, the aircraft doesnt make a bad impression, because it looked as if it was unarmed. But a short time away, the atomic bomb detonated 600 metres over Hiroshima. This bomb killed 200, 000 people. The shock wave, with the maximum speed of 1200 km/h, destroyed all the buildings within a radius of 1, 5 kilometre. The windows smashed even in a distance of 12 kilometres. The head wave and the radioactive radiation killed all the people within a radius of several kilometres. The radioactive radiation in the first minutes after the detonation, and the fallout in the first day after the detonation contaminated all the city. 3 days after this, on 9 August 1945, the terrible disaster repated itself with the same course and the same result like in Hiroshima in the second nuclear attack on Nagasaki. And with them another 74, 000 people died and again many people were contaminate.
- The fallout - The head wave - The shock wave - The nuclear electromagnetic pulse These are the results of an atomic bomb with the size of the Hiroshima- bomb: - The radioactive radiation contaminated the city with a strong radiation.
This radiation killed all the people there.
- The detonation whirl up a lot of dust or water, this dust or water is contaminate radioactive and fly several kilometres up. Then in the first day after the detonation, this radioactive dust or water rain down, back on the earth and contaminate a big floorspace. This rain is the fallout.
- The head wave come about the gigantic energy, they develop by the detonation. In the detonation centre reach the temperature of several millions degrees centigrade. The head wave takes only a few seconds, but it kill all the people within a radius of 1 or 2 kilometres. Even ...
