Molybdenum-97 is a radioactive isotope of the element molybdenum, with a half-life of about 1.5 million years. It is primarily used in the production of technetium-99m, a widely used radioisotope in medical imaging. Molybdenum-97 decays into technetium-97, which has applications in various fields, including nuclear medicine. This isotope is produced in nuclear reactors and is essential for diagnostic procedures, such as PET scans and SPECT imaging. Its ability to emit gamma rays makes it valuable for visualizing internal organs and detecting diseases, including cancer.
