Preferred Name: Palladium Pd-103

Definition: A radioisotope of the metal palladium used in brachytherapy implants or 'seed'. With a half-life of 17 days, palladium 103 administered with brachytherapy allows continuous, tumor-site specific low-energy irradiation to the tumor cell population while sparing normal adjacent tissues from radiotoxicity. (NCI04)

NCI-GLOSS Definition: A radioactive form of palladium (a metallic element that resembles platinum). When used to treat prostate cancer, radioactive seeds (small pellets that contain radioactive palladium) are placed in the prostate. Cancer cells are killed by the energy given off as the radioactive material breaks down and becomes more stable.
