Other Names:Xenon Isotope
CAS NO: 7440-63-3
Grade Standard:Electron Grade,Industrial Grade,Medicine GradeMSDS
Naturally occurring xenon (54Xe) is made of eight stable isotopes and one very long-lived isotope. (124Xe, 126Xe, and 134Xe are predicted to undergo double beta decay, but this has never been observed in these isotopes, so they are considered to be stable.)[not in citation given] Xenon has the second-highest number of stable isotopes. Only tin, with 10 stable isotopes, has more. Beyond these stable forms, over 30 unstable isotopes and isomers have been studied, the longest-lived of which is 136Xe, which undergoes double beta decay with a half-life of 2.165 ± 0.016(stat) ± 0.059(sys) ×1021 years with the next longest lived being 127Xe with a half-life of 36.345 days. Of known isomers, the longest-lived is 131mXe with a half-life of 11.934 days. 129Xe is produced by beta decay of 129I (half-life: 16 million years); 131mXe, 133Xe, 133mXe, and 135Xe are some of the fission products of both 235U and 239Pu,so are used as indicators of nuclear explosions.
