The positive aspects of the use of nuclear energy are that the supply of natural resources does not have to be depleted, and also it is clean. It takes a great amount of natural resources to create a small amount of energy. On the other hand, a very small amount of plutonium and uranium is necessary for the creation of a large amount of nuclear energy. This is important since there are relatively small amounts of plutonium and uranium in the earth’s crust. Compared to the production of power using coal, the creation of power generated by nuclear energy does not pollute the air. As coal burns, there are poisonous fumes that could cause sickness, if the area is not properly ventilated. As the cost of electricity rose, the government was forced to look for an alternative source of energy, which they discovered in nuclear reactors.
One of the major disadvantages of a reactor is the disposal of the nuclear waste which harms the environment. “There are 434 nuclear reactors in the world and 110 of them are in the United States. Not a single one is functioning without polluting the environment. Attempts to store nuclear wastes have not been very successful. One such attempt is to bury the nuclear waste underground, but the leakage of nuclear waste has poisoned the groundwater. Another attempt is to put the nuclear waste into deep ocean water. Later, this was rejected by the public and also, in violation of an international treaty because of the possibility of harming the ocean. Another problem to the environment is the leakage of radioactive waste from space. This problem is not pollution to the earth’s environment, but pollution of space. There is no way to dispose of the nuclear waste in space.
The most significant drawback on this controversial issue is the threat of a disaster. The two most serious situations were the accident at Chernobyl and the explosion of the hydrogen bomb on Hiroshima. The first time that people discovered the dangers of nuclear power was when the atomic bomb was dropped, August 6, 1945, on Hiroshima. The effects of the bomb was that it destroyed 4.7 square miles of the city. Approximately 70,000 people were killed and about another 70,0000 people were injured. Many people died later as a result of nuclear radiation and radiation sickness. The most serious nuclear disaster was the Chernobyl accident that occurred April 26, 1986 in the Soviet Union. An accurate number of deaths as a result of this accident is very hard to determine due to the secrecy of the U.S.S.R. surrounding this accident. A study done by a team of scientists from both the United States and Japan has shown that there has not been any evidence found of genetic mutation, which are changes in heredity, in the children of the survivors of the bombing of Hiroshima.
Following the Chernobyl accident, Soviet scientists suggest that there is evidence that radiation has exhibited genetic mutation in the parents who were exposed to radiation. According to them, the mutation was found in sperm and egg cells, which contain the genetic building blocks of future generations. The child’s DNA is a combination from both parents’ genetic makeup. When there is any sequence that the child has, but that sequence was not found in either parent, then this is called germline mutation. Ten years after the accident that occurred at Chernobyl, evidence of mutation, in the exposed areas of the country, indicates that radiation changed genetic makeup and that this has passed onto future generations. Also, there has been an explosive increase in childhood thyroid cancer in Belarus, Ukraine and the Russian Federation since 1986. This cancer is present in brothers and sisters of the same family, which indicates that the cancer is a result of the accident at Chernobyl.
