Selenium has six by itself occurring isotopes, 5 of which are stable: 74Se, 76Se, 77Se, 78Se, and 80Se. The endure three aswell action as fission products, forth with 79Se, which has a half-life of 327,000 years.
The final by itself occurring isotope, 82Se, has a actual continued half-life (~1020 yr, corrupt via bifold beta adulteration to 82Kr), which, for applied purposes, can be advised to be stable. Twenty-three added ambiguous isotopes accept been characterized.
