Ruthenium Isotopes are used in several scientific and medical applications. Ru-99 is used for NMR studies. Ru-96 is used for the production of the radioisotopes Ru-94 and Ru-95. Ru-98 has been used to study excitations in atomic nuclei. Ru-100 has been used in isomeric cross section studies. Ru-101 has been used in studies related to the structure and vibrations of nuclei. Ru-102 has been used as a target for the production of the radioisotope Te-116. Ru-104 is used for the production of the radioisotope Rh-105 which has been suggested for the treatment of bone pain.
