History of the Atomic Bomb The atomic bomb 1 is the most destructive weapon known to mankind. A bomb of this nature is capable of obliterating anything up to four square miles and anything reaching outside that area receives very extreme damage. Albert Einstein was the man who had convinced the United States to research the Atomic Bomb. The Manhattan Project 2 was the name given to the research and development of the atomic bomb. It was called the Manhattan Project after Manhattan Engineer District of the US Army Corps of Engineers, because most of the early research was done in New York.

The person that was chosen to lead this project was General Leslie Grove and Robert Oppenheimer was appointed to lead the day-to-day running of the project. In order for an atom bomb to be produced the scientists had to separate the Uranium-235 from the much more common Uranium-238. The facility that was used to separate the Uranium-135 from the Uranium-238 was not held 1 Atomic Bomb - Bomb using Uranium-235 for mass destruction. 2 Manhattan Project - Name given to the development and research of the atomic bomb in the U. S. in New York but in Oak Ridge, Tennessee.

The cost of this project was two billion dollars, which is equivalent to 26 billion dollars in today's world and the factories employed 200, 000 people, that was more then the amount of people employed in the United States auto mobile industry. When the first bomb was made a site in Alamogordo, New Mexico was chosen as the testing ground. In order for the bomb to explode, all the nuclei of the several grams of Uranium would have to be split. A sphere of Uranium the size of a baseball would cause an explosion that equaled the strength of 15, 000 to 20, 000 tons of TNT.

When the bomb had exploded there was a tower and the explosion had turned the asphalt around the tower into green sand, the sky was extremely bright and seconds after the explosion came a huge blast that sent unbelievable heat across the desert. Also, there was a huge mushroom cloud that reached the sub-stratosphere that was at an elevation of 41, 000 feet. 10, 000 feet away a soldier was of right off his feet by the force of the shock wave and another soldier stationed five miles away was temporarily blinded. The explosion was able to be herd 50 miles away. The first time the United States used the atomic bomb was during World War II. They had dropped a bomb on the city of Hiroshima in Japan and then on the city of Nagasaki in Japan.

The first bomb was dropped on Hiroshima and it was named "1 Little Boy." Even though it was the smaller of the two bombs dropped, "Little Boy" caused the most damage. It destroyed about 80 percent of Hiroshima's buildings and killed about 80, 000 people. The heat that was generated burned everything in it's path including people and melted glass and tile. Plus powerful wind destroyed most of the houses and buildings within a 1.

5-mile radius. When the wind reached the mountains, it was then reflected and hit the city center for a second time. The second bomb, which was dropped on the city of Nagasaki, was named "2 Fat Man." Even though this atomic bomb was bigger it caused less damage then "Little boy." Fat Man had only killed 70, 000 civilians. As a result of the bombing there was radiation that caused long-term problems to the people of the two cities. Some people gave birth to malformed babies and other became unable to even bare children. Due to the bombing an estimated 200, 000 people perished by the end of the year.

When an Atomic Bomb explodes it releases unbelievable amounts of deadly radiation. Those people that were exposed 500 meters from ground zero of the blast died instantly and those people that were 3 to 5 kilometers away later showed symptoms of aftereffects, including radiation-induced 1 "Little Boy" - First bomb ever used in warfare; weighed 4 tons. 2 "Fat Man" - Second bomb ever used Cancers. There were many acute symptoms that had showed up. Some of these symptoms are: 1 general malaise, fatigue, headaches, loss of appetite, nausea, vomiting, diarrhea, fever, abnormally low white blood cell count, bloody discharge, anemia and loss of hair.

Injuries that showed up after the bombing were 2 keloid's, cataracts, leukemia and other cancers. It takes hundreds of years for the radiation to leave the bomb site and for everything to be stable again. The Atomic Bomb was the breeding ground for many more nuclear inventions. From the atomic bomb they came up with 3 nuclear power. Nuclear power was much better then the burning of fossil fuels. The earth has only limited amounts of coal and oil.

The people cannot rely on using fossil fuels because eventually it will run out. A nuclear power plant needs less fuel then the old fossil fuel burning power plants. One ton of uranium produces more energy then several million tons of coals or several million barrels of oil. Also a coal or oil burning power plant would pollute the air. A well-maintained nuclear power plant does not contaminate the air at all. Another invention was the nuclear powered submarine.

These submarines 1 General Malaise - Feeling weak. 2 Keloid's - A thick scar resulting from the excessive growth of fibrous tissue. 3 Nuclear Power - Usage of uranium to generate power. are capable of traveling longer distances and stay submersed longer then regular submarines.
