Samarium Isotopes are used in various applications. Sm-144 is used for the production of the therapeutic radioisotope Sm-145. Sm-147 has been bombarded with Ca-40 to produce the short-lived radioisotopes Pb-182. Sm-148 has been used to study the giant monopole resonance while Sm-149 has been used in a filter for polarizing thermal neutrons. Sm-152 is used for the production of the radioisotope Sm-153 which is used for bone pain palliation. Finally, Sm-154 has been used to study the excited states of Sm-153.
