We can think hundreds of such goods that were not used before and we are using them today in order to satisfy our wants and to meet our needs: from walkman to cars, from computers to bank machines. Of course, there are thousands of businesses and manufacturers that supply all these products/services and they all require energy to work.

Can we imagine our "modern" world without electricity? Can we imagine it, without the kind of energy that produces electricity? Purpose of this text is to examine one basic source of energy-nuclear energy. This text will discuss advantages and disadvantages of nuclear power.

We will examine the basic points about nuclear energy and we will compare them to the usage of other energy sources. But, what do we mean by nuclear energy?

Nuclear energy refers to the energy that we can obtain if we split atoms. Atoms have neutrons, protons (both in nucleus) and electrons (around nucleus). If nucleus breaks up, huge amount of energy is released. This procedure is called fission.

For someone to receive 75-200 rems of exposure, vomiting, fatigue, and loss of appetite would occur. Recovery would take a few weeks. If someone were to be exposed to more than 300 rems, severe changes in blood cells and hemorrhage takes place. If someone were to receive more than 600 rems, symptoms would be hair loss, loss in your body’s ability to fight infection and usually results in death. (World Book vol. 16,79)

Nuclear energy was, is and will be a very powerful form of energy. Actually it is the most powerful- and has many dangers for our health, for the environment and for every type of life into the planet.

Nowadays, we are using all the above ways to produce energy and scientists are trying to improve their applications in order to achieve the maximum benefits and to reduce the financial/environmental cost(s). The amount of energy differs from each method, as well, as the dangers for people and environment. Nuclear energy is a great source but it has many "traps" and dangers.

Nuclear power plants generate only about eleven percent of the world’s electricity. There are around 316 nuclear power plants in the world that creates 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms’ nucleus’ split and cause a nuclear reaction.
