Osmium isotopes are used for the production of radioisotopes and in scientific experiments. Os-192 can be used for the production of the medical radioisotope Pt-195m. Os-184 is used for the production of the radioisotope Os-185. Os-191 can be used for the production of the radioisotopes Os-192. Os-190 has been used as a tracer to determine Os abundance in meteorites using isotope dilution ICP-MS. Finally, Os-189 has been used to experiment with nuclear excitation by electronic transition.
