Nuclear energy is the energy released during nuclear fission or fusion, especially when used to generate electricity. It is also known as atomic energy. Nuclear energy is the energy in the nucleus of an atom. Atoms are the smallest particle that can break a material. At the core of each atom, there are two types of a particle (neutrons and protons) that are held together. Nuclear energy is the energy that holds neutrons and protons.

Nuclear energy can be used to produce electricity. This energy can be obtained in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. The sun produces energy like this. In nuclear fission, atoms are split into smaller atoms, releasing energy. Actually, nuclear power plants can only use nuclear fission to produce electricity.

This is not the only use of this energy. This type of energy appears in many other aspects of our life and in science. Nuclear power has other applications in various, Industrial application: for analysis and process control. Medical application: in diagnosis and therapy of diseases. Applications in food processing in the production of new species, conservation treatments of food, pest insects and vaccine preparation. The use of nuclear power in modern industry in developed countries is very important for improving processes of measurement, automation and quality control.

The use of radiation is applied in a wide range of activities, either in quality control of industrial processes, raw materials like cement, power plants, oil refineries etc.

The application of radionuclides related to human health emerged quickly after the discovery of X-rays. At present, most of the hospitals and health centres have a Radiological Department of Nuclear Medicine and radio chemical laboratory methods used for diagnosis and investigation of a variety of diseases. In nuclear medicine, a particular radionuclide is administrated to the patient, in order to investigate a specific physiological phenomenon by means of a special detector, a gamma camera generally located outside the body. The injected radionuclide is deposited selectively in certain organs like thyroid; kidney etc can be seen from the gamma camera, the size, shape and function of these organs.

Global warming formula probably is most harmful to the environment. This is due to the release of gases during the combustion of organic material i.e. carbonyl like oil, wood and garbage.

Nuclear power allows the use of isotropic analysis that calculates the carbon dioxide emission in an industrial area. Nuclear methods such as electron beam irradiation are very useful for removing gaseous pollutants, including harmful gases like sulphur dioxide or nitrogen oxide emitted in carbonyl fuel power plants.

Method to calculate the carbon dioxide emission is the observation of the plants growing in an industrial area, which capture radio carbon-14 from cosmic radiation, as carbon dioxide and also incorporate emitted by industries, by determining what proportion of radioactive andĀ  non-radioactive carbonĀ  can determine the total emission of carbon dioxide in that area. Thus in the end, we can say that nuclear energy has both advantages and disadvantages to the mankind. But we cannot ignore the importance of nuclear energy which is helping human to overcome those difficulties than no other can do.
