Palladium Isotopes are used in a variety of scientific applications. Pd-104 is used for the production of radioactive Pd-103 seeds which are used to fight prostate cancer. Pd-103 can also be made from Pd-102. Other Pd isotopes such as Pd-110 and Pd-108 have been used in physical experiments such as research into the decay of Nd-137 and nuclear fusion phenomena. Pd-108 can also be used for the production of radioactive Pd-109 which is used for cancer therapy.
