Naturally occurring xenon (54 Xe) consists of seven stable isotopes and two very long-lived isotopes. Double electron capture has been observed in 124 Xe (half-life 1.8 ± 0.5(stat) ± 0.1(sys) × 10 22 years) [2] and double beta decay in 136 Xe (half-life 2.165 ± 0.016(stat) ± 0.059(sys) × 10 21 years), [7] which are among the longest measured half-lives of all nuclides.
It has seven stable isotopes (126 Xe, 128 Xe, 129 Xe, 130 Xe, 131 Xe, 132 Xe, 134 Xe) and two isotopes (124 Xe, 136 Xe) with long-lived half-lives. Xe has four synthetic radioisotopes with very short half-lives, usually less than one month. Xenon-129 can be used to examine the early history of the Earth.

More than 40 unstable xenon isotopes undergo radioactive decay, and the isotope ratios of xenon are an important tool for studying the early history of the Solar System. [28] Radioactive xenon-135 is produced by beta decay from iodine-135 (a product of nuclear fission ), and is the most significant (and unwanted) neutron absorber in nuclear ...
The noble gases up to xenon have multiple stable isotopes; krypton and xenon also have naturally occurring radioisotopes, namely 78 Kr, 124 Xe, and 136 Xe, all have very long lives (> 10 21 years) and can undergo double electron capture or double beta decay.
