Nuclear physicists are scientists who study the components and behavior of atomic nuclei. They explore the forces that hold the nucleus together, the processes of nuclear reactions, and the properties of different isotopes. Their work is essential for understanding phenomena such as radioactivity, nuclear fission, and nuclear fusion. These physicists often work in research laboratories, universities, or government facilities. Their findings contribute to various fields, including energy production, medical imaging, and radiation therapy. By advancing our knowledge of nuclear processes, they help develop new technologies and improve safety in nuclear applications.
