Molybdenum Isotopes have several applications. Mo-95 is used for the production of the medical radioisotope Ru-97. Mo-96 is used for the production of the radioisotopes Tc-96 and Tc-95m, both of which have a medical application. Most Mo isotopes are also used in nutrition studies in humans. Depleted Mo-95 has been suggested for use in UMo fuel elements for materials test (high flux) reactors. Mo 100 is currently very in high demand.
