Atomic Bomb, powerful explosive nuclear weapon fueled by the splitting uranium or plutonium in a chain reaction. The strength of the explosion created by an atomic bomb is equal to 22000 tons of tnt, Usually the plutonium or uranium in a bomb is separated into parts so that an explosion or critical mass is not reached until the bomb is set to explode. This process releases a lot of energy in the form of heat and powerful shock wave; this is the intense explosion. In addition to its destructive power, made up of pressure waves, flashes, burns, and high winds, a nuclear explosion also produces deadly radiation. The radiation destroys living things and contaminates soil and water.
Atomic bombs were the first nuclear weapons to be developed, tested, and used. In the 1930s scientists in Europe and the United States discovered that the splitting of uranium could be used to create an extremely powerful explosive weapon.
The U.S. government started top secret Manhattan Project in 1942 to develop an atomic bomb. The leader of the Manhattan Project was U.S. Army General Leslie R. Groves. His team, wat working in several locations but in large part at, New Mexico where she designed and built the first atomic bombs.
The first atomic explosion was done, as a test, at Alamogordo, New Mexico, on July 16, 1945. The energy released from this explosion was equal to the explosion of 20,000 tons of TNT. Near the end of World War II, on August 6, 1945, the United States dropped the first atomic bomb on Japan in the city of Hiroshima. It followed with a second bomb against the city of Nagasaki on August 9. According to the U.S., 60,000 to 70,000 people were killed by the Hiroshima bomb, called "Little Boy,"...
