Technetium-97 is a radioactive isotope of the element technetium, which has the atomic number 43. It is not found naturally in significant amounts and is typically produced in nuclear reactors or through the decay of other isotopes. Technetium-97 has a half-life of about 2.6 million years, making it relatively stable compared to other isotopes. This isotope is primarily used in scientific research and has potential applications in nuclear medicine. Its properties allow for the study of various processes, including the behavior of nuclear waste and the development of new imaging techniques.
