Implants pour les cancers de la prostate
Implants have the size of a grain of rice. Two artificial radioelements are used, iodine-125 (I-125) and palladium-123 (Pd-103). These two radioisotopes emit low energy electrons and X-Rays. The electrons are not energetic enough to come out of the implants. The irradiation is due to X-rays which are mainly absorbed in the "prostate" tissues surrounding the implant.
