fissions of uranium or plutonium atoms in a chain reaction, each fission releasing tremendous energy and also neutrons which produce the succeeding fission (The World Book Dictionary 129). In other words, these bombs are very powerful. This was demonstrated in 1940, when we dropped an Atomic Bomb on Hiroshima during World War II. This bomb left a crater, in the ground, that was over a half of a mile long.

One of the first instances that these bombs were used was called the Manhattan Project. The Manhattan Project was created by the United States government in 1942 to produce the first nuclear bomb. The official agency that produced the bomb was the Corps of Engineers' Manhattan Engineer District, commanded by Major General Leslie R.Groves. He directed industrial and research activities at such sites as Oak Ridge, Tennessee, and Los Alamos, New Mexico (The World Book Encyclopedia 141). Here they designed to bombs that were later called "The Fat Man" and "The Little Boy".

In the past, there were very many nuclear accidents. One of these was in 1982. International Nutronics in Dover, New Jersey, which used radiation baths to purify gems, chemicals, food, and medical supplies, experienced an accident that completely contaminated the plant, forcing its closure. A pump malfunctioned, siphoning water from the baths onto the floor; the water eventually was drained into the sewer system of the heavily populated town of Dover. The NRC wasn't informed of the accident until ten months later. In 1986, the company and one of its top executives were convicted by a federal jury of conspiracy and fraud. Radiation has been detected in the vicinity of the plant, but the levels are thought to be nondangerous. This shows how dangerous the stuff that these bombs are made out of is. Just the fact that this incident happened 17 years ago, and there are still levels of radiation in the area that are being detected.

There are also some precautions that can be taken so that these accidents cannot harm those that have been working around it. One of these is for minor accidents and spills without radiational hazard to the personnel. In the case of this type of accident you
