Many Dysprosium Isotopes have been the subject of physics research. Dy-156 has been used to study double electron capture while Dy-160 has been used in research to investigate its multitude of excited states. Dy-161 spectroscopy has been used to determine the properties of Dysprosium based superconductor material. Dy-162 has been used to study excited states in deformed nuclei. Dy-164 has two medical applications. It is used in the production of Dy-165 which is used in arthritis therapy. Dy-164 is also used for the production of Dy-166 which decays to Ho-166 and this used in cancer therapy. The Dy-164 to Ho-166 route gives the advantage of generating so-called carrier free material.
