Nuclear chemistry is the study of the chemical and physical properties of elements as influenced by changes in the structure of the atomic nucleus. It involves understanding radioactive decay, nuclear reactions, and the behavior of isotopes. This field plays a crucial role in various applications, including medicine, energy production, and environmental science. Researchers in nuclear chemistry explore processes such as fission and fusion, which release energy from atomic nuclei. They also investigate the use of radioisotopes in medical imaging and treatment, as well as their role in dating archaeological artifacts through radiocarbon dating.
