    en.wikipedia.org/wiki/Iodine-125

    Iodine-125 (125 I) is a radioisotope of iodine which has uses in biological assays, nuclear medicine imaging and in radiation therapy as brachytherapy to treat a number of conditions, including prostate cancer, uveal melanomas, and brain tumors. It is the second longest-lived radioisotope of iodine, after iodine-129.

    en.wikipedia.org/wiki/Xenon

    In nuclear energy studies, xenon is used in bubble chambers, [188] probes, and in other areas where a high molecular weight and inert chemistry is desirable. A by-product of nuclear weapon testing is the release of radioactive xenon-133 and xenon-135 .

  5. Radioactive tracer - Wikipedia

    en.wikipedia.org/wiki/Radioactive_tracer

    125 I is frequently used in radioimmunoassays because of its relatively long half-life (59 days) and ability to be detected with high sensitivity by gamma counters. [8] 129 I is present in the environment as a result of the testing of nuclear weapons in the atmosphere. It was also produced in the Chernobyl and Fukushima disasters.
