The Atomic Bomb

.. of the atom bombs are terrible. In Hiroshima, the united states “Little Boy”, a uranium bomb, was dropped on August 6th, 1945. “At the moment of the explosion, a fireball was generated with a center, which reached a temperature of several million degrees Celsius. The heat rays released in all directions had a strong effect on the ground for about three seconds, starting approximately 1/100 second after the detonation.

Due to the heat rays, the temperature in the hypocenter area is believed to have reached 3,000-4,000 Celsius Iron melts at 1,536 Celsius.” (History of Hiroshima and Nagasaki Atomic Bomb damage Mar. 99 It killed 66,000 and injured 69,000 people. The atomic bomb blast in 1945 obliterated three-fifths of the city within seconds. On Aug. 9, 1945, an U.S.

bomber dropped a plutonium atomic bomb on Nagasaki. They aimed this at the Mitsubishi shipyards. The bomb missed its target but destroyed about half of the city and killed approximately 75,000 and injuring 25,000 people. This aftermath has left an enduring mark on the world. The radiation from the blasts has since caused many deaths.

People that subsided within approximately five months after the blast are considered to have acute effects. “Acute effects include digestive tract disorders (nausea, loss of appetite, diarrhea); nervous disorders (headache, delirium, insomnia); fatigue (loss of hair, loss of energy, weakness); bleeding (blood in vomit, blood in urine, blood in stool, purpura); infection (fever, stomatitis, skin infections); blood disorders (loss of red or white blood cells); and reproductive disorders (zoospermia, menstrual disorders).” (History of Hiroshima and Nagasaki Atomic Bomb damage Mar. 99 after acute effects, there were many other complications. Such as Keloids, Leukimia, Cancer, In-utero exposure and Genetic Effects. The rates of these problems increased many years after the bombing.

After 1945, the United States built thousands of atomic bombs. In addition, the more powerful hydrogen bombs. “In 1945 the United States was the only country to have nuclear capabilities. The U.S.S.R obtained them in 1949, Britain in 52,France in 1960, the People’s Republic of China in 1964, and India in 1974.” (Grolier Multimedia Encyclopedia The Atomic Bomb Mar.99 CD-ROM NP) The United States Government and many other people regret having used the atom bomb. Many other countries have now made these terrible weapons of destruction.

The making of this has only been a scar upon the world. Nuclear weapons led to many other problems in our world like the cold war. Many geniuses went to work to make great advancements in nuclear technology. It is a shame we could not have used these findings for a good cause. Brett Skyllingstad An Eyewitness Account by a Middle School Student The following is from an eyewitness account by a middle school student who was in a classroom during the bombing. The student managed to escape the collapsed school building but suffered injuries.

I’ll never forget that day. After we finished our morning greetings in the schoolyard, we were waiting in the classroom for our building demolition work to begin. Suddenly a friend by the window shouted ‘B- 29!’ At the same instant, a flash pierced my eyes. The entire building collapsed at once and we were trapped underneath. I don’t know how long I remained unconscious. When I came to, I couldn’t move my body.

Cuts on my face and hands throbbed with pain. My front teeth were broken and my shirt soaked in blood. As I crawled along, encouraging myself, I somehow managed to poke my head out of the wreckage. The school that should have appeared before my eyes was nowhere to be seen. It had vanished and only smoldering ruins remained. Beyond the school toward the center of town, all I could see was a sea of flames.

I was so terrified I couldn’t stop shaking. Moving my body a little at a time, I was finally able to work free of the collapsed structure. Making sure to head upwind to escape the fires, I made my way staggering haphazardly through the rubble of the city and escaped.

It was caused from the intense heat. 9 This shadow was made by a person sitting on the steps in front of the bank entrance waiting for it to open. The flash probably hit the victim from the front dying on the spot. The surface of the surrounding stone was significantly whitened by exposure to the bombs heat rays, but the place where the person sat remained dark. 10 This is a picture of Enrico Fermi.

The Atomic Bomb

The Atomic Bomb The atomic bomb has been a major turning point in history. It started out when Roosevelt signed a document for a group of scientists to start creating the bomb. The scientists thought they could purify uranium 235 to be used as a form of nuclear warfare. The name of the top secret project was The Manhattan Project named after the Manhattan Engineer District of the US Army Corps of Engineers due to the great amount of early research done in New York. Scientists working on the atomic bomb needed to separate uranium 235 from the common uranium 238.

The scientists worked six days a week, 18 hours a day. By 1945 the project had 40 labs and factories and employed 200,000 people, more than the automobile industry that year. The project spent $2 billion which is equivalent to $26 billion today. After much research I decided that it was better to bomb Nagasaki and Hiroshima than the US to loose many more of its soldiers. The US probably dropped the bomb because the Japanese would not have surrendered unless.

There would have been thousands of US casualties by fighting Japan with ground troops. The atomic bomb was a very costly project and wouldn’t have gone well if millions was spent making a bomb and it was never used. Other reasons are the Japanese were abusive to US prisoners of War and to show the US technology was superior to that of the USSR. On August 6th, 1945 the first atomic bomb was dropped on the city of Hiroshima. The explosion killed 90,000 to 140,000 people.

The bomb devastated 4 sq. miles of land and damaged outside areas severely.
