Nuclear energy is the energy released during nuclear reactions, either through nuclear fission (splitting of atomic nuclei) or nuclear fusion (combining atomic nuclei). It is a powerful and concentrated form of energy.
The unit commonly used to measure nuclear energy is the electron volt (eV) or the joule (J), where 1 electron volt is approximately 1.602×10−19 joules.
If we consider 1 joule of nuclear energy, it would be equivalent to the energy released by a small nucleus undergoing a nuclear reaction.
Some daily life examples of Nuclear Energy are listed below:
- Nuclear power plants generating electricity.
- Medical applications, such as in radiation therapy.
- Smoke detectors utilizing radioactive materials.
- Nuclear submarines propelled by nuclear reactors.
- Food irradiation for preservation.
- Radiocarbon dating in archaeology.
- Nuclear medicine imaging techniques (PET scans).
- Nuclear-powered spacecraft.
- Industrial radiography for inspecting welds and materials.
- Research and development in nuclear physics.
Types of Nuclear Energy
- Nuclear Fission: The splitting of atomic nuclei, releasing energy.
- Nuclear Fusion: The combining of atomic nuclei to release energy.
