| iodine-127 | <radiobiology> Stable, nonradioactive iodine, the most abundant iodide isotope found in nature; dietary deficiency causes simple goiter; used to block thyroid uptake of radioactive iodine released from nuclear accidents. (05 Mar 2000) |

| xenon | <chemical> A noble gas with the atomic symbol xe, atomic number 54, and atomic weight 131.30. It is found in the earth's atmosphere and has been used as an anaesthetic. Pharmacological action: anaesthetics, inhalation. Chemical name: Xenon (12 Dec 1998) |
| xenon 133 | <radiology> Xe-133, half-life: 5.2 days, 80 keV photon, dose for V/Q imaging = 20 mCi Cf: other lung ventilation agents (12 Dec 1998) |
| xenon-133 | A radioisotope of xenon with a gamma emission at 81 keV and a physical half-life of 5.243 days; used in the study of pulmonary function and organ blood flow. (05 Mar 2000) |
| xenon isotopes | Stable xenon atoms that have the same atomic number as the element xenon, but differ in atomic weight. Xe-124, 126, 128-131, 134, and 136 are stable xenon isotopes. (12 Dec 1998) |
| xenon radioisotopes | Unstable isotopes of xenon that decay or disintegrate emitting radiation. Xe atoms with atomic weights 121-123, 125, 127, 133, 135, 137-145 are radioactive xenon isotopes. (12 Dec 1998) |
