 * __How A Nuclear Bomb Works__**

Nuclear bombs are the most powerful weapon ever to be used in military battle and can do serious destruction. Nuclear bombs involve the forces, strong and weak, that hold the nucleus of an atom, especially unstable nuclei. The nuclear energy released, which makes the bomb happen, can be releases in two ways, through nuclear fusion and nuclear fission. In both, large amounts of heat energy and radiation are given off. The first nuclear bombs were fission devices, and the later fusion bombs required a fission-bomb trigger.

^^yo doc check this out

There are three main objects you need to create a nuclear bomb, a source of fissionable or fusionable fuel, a trigger device, and a long cord or fuse so that you are not close to the bomb when it goes off. Nuclear bombs occur by a nuetron approaching a nucleus of a uranium-235. When the nucleus meets the nuetron the atom splits into two less dense atoms, also throwing out two or three extra nuetrons. When the atom splits it releases a very large amount of energy, in the form of gamma radiation. In a high functualing bomb like this one, usually when the couple nuetrons are releases the then form the process to happen all over again by hitting another nucleus.

nuclear bombs often leave a cloud of smoke resembling a mushroom

When a nuclear bomb is detonated then the results and health risks can be deadly. If it goes off near a populated area such as a city or town then all the people in the town or city will most likely be killed. How bad the damage can be all depends on how close that city is to the center of the blast, aka the hypocenter. In the hypocenter temperatures can reach up to 500 million degrees and everything in that center is immediately vaporized. When the bomb goes off many things happen and they all effect the damage that is caused. One thing that occurs as a nuclear bomb explodes is an intense heat wave is released. Also large amounts of pressure build up due to the explosion and that pressure is released crushing anything in its path. Radiation is another deadly thing that is released from a nuclear explosion and the radiation is what usually kills people because our bodies can not fight against it. Finally damage is caused by radioactive fallout, which is clouds of radioactive debris is and clouds off dust rain down on the area surrounding the blast. Some health risks that may result in being exposed to some of the radiation can be cancer, leukemia, birth defects, loss of blood cells, loss of hair, and cataracts. If you survive one of these nuclear blasts without suffering form any of these consequences then you are a god or you have a protective suite.

The history of the nuclear bomb did not start in the united states but over in Germany by the Nazi's. The US did not actually get word of it until Albert Einstein and other scientist wrote a letter to President Franklin D. Roosevelt informing him on what was going on. The US government quickly put together what was known as The Manhattan Project. This project had a simple goal. Their goal was to find a way to purify uranium-235 and find out how to make a nuclear bomb. The hardest task they faced was trying to find enough uranium-235 to produce the atomic bomb. When they finally did they were able to make a fine atomic bomb and it definitely got the job done in world war 2.

Nuclear bombs may be one of the most complicated weapons in the world but they are also the most destructive and there damages do not go unnoticed. They may be the most powerful weapon to every be created, but i doubt that with the way our future is coming. They are the most complicated weapon to be built and you have to be very smart along with have a very good idea of chemistry to be able to handle them and build them. They cause enormous amounts of destruction to human life and the planet itself. Finally they were not built by Americans just perfected by us. But they are a very complex weapon and hopefully they will not have to be brought into another war no matter what counties are fighting.

"I do not believe that civilization will be wiped out in a way fought with the atomic bomb. Perhaps two-thirds of the people of earth will be killed." -Albert Einstein
