Technetium-95 is a radioactive isotope of the element technetium, which has the atomic number 43. It is produced through the decay of molybdenum-95 and has a half-life of about 61 days. This isotope is not found naturally in significant amounts and is typically generated in nuclear reactors or during the decay of other isotopes. Due to its radioactive properties, technetium-95 is primarily used in scientific research and medical applications, particularly in the field of nuclear medicine. It can be utilized in imaging techniques, helping doctors diagnose various conditions by providing detailed images of internal organs.
