Naturally occurringrhenium (₇₅Re) is 37.4%¹⁸⁵Re, which isstable (although it ispredicted to decay), and 62.6%¹⁸⁷Re, which isunstable but has a very longhalf-life (4.16×10¹⁰ years). Among elements with a known stable isotope, onlyindium andtellurium similarly occur with a stable isotope in lower abundance than the long-lived radioactive isotope.

There are 36 other unstable isotopes recognized, the longest-lived of which are¹⁸³Re with a half-life of 70 days,¹⁸⁴Re with a half-life of 35.4 days,¹⁸⁶Re with a half-life of 3.7185 days,¹⁸²Re with a half-life of 64.2 hours, and¹⁸⁹Re with a half-life of 24.3 hours. There are also numerousisomers, the longest-lived of which are^186mRe with a half-life of 200,000 years and^184mRe with a half-life of 177.25 days.^[4] All others have half-lives less than a day.
