Of the nine stable Xenon Isotopes, several are used in various medical and scientific applications. Xe-124 is used in the production of two radioisotopes: I-123 and I-125. I-123 is used extensively in diagnostic procedures while I-125 is used in the treatment of prostate cancer. Hyperpolarized Xe-129 is used in the magnetic resonance imaging of gas flows in the lungs. Xe-136 has been proposed as a detector for neutrinoless double Beta decay research. Xe-126 can be used as a target for the production of radioactive Ba-128.
