Nuclear Chemistry is the study of the chemical and physical properties of elements that are influenced by changes in the structure of the nucleus. This field explores phenomena such as radioactivity, nuclear fission, and nuclear fusion, which are essential for understanding both natural processes and human-made applications like nuclear energy. In addition to its applications in energy production, Nuclear Chemistry plays a crucial role in medicine, particularly in radiotherapy and nuclear imaging. By harnessing the properties of radioactive isotopes, scientists can develop techniques for diagnosing and treating various diseases, showcasing the importance of this field in both science and healthcare.
