Selenium has six naturally occurring isotopes, five of which are stable: 74Se, 76Se, 77Se, 78Se, and 80Se. The last three also occur as fission products, along with 79Se, which has a half-life of 327,000 years.
The final naturally occurring isotope, 82Se, has a very long half-life (~1020 yr, decaying via double beta decay to 82Kr), which, for practical purposes, can be considered to be stable.
Twenty-three other unstable isotopes have been characterized

The last three also occur as fission products, along with 79Se which has a half-life of 327,000 years, and 82Se which has a very long half-life (~1020 yr, decaying via double beta decay to 82Kr) and for practical purposes can be considered to be stable. 23 other unstable isotopes have been characterized, the longest-lived being 79Se with a half-life 327,000 years, 75Se with a half-life of 120 days, and 72Se with a half-life of 8.40 days. All other isotopes have half-lives less than 8 hours, most less than 38 seconds, which of these, 73Se is the most stable, with a half-life of 7.15 hours.
Is selenium poisonous?
A:Yes they use it in atom bombs. A:There are no stable isotopes of uranium - it is all radioactive.

What is the decay product of selenium?
You need to specify not just the element, but the specific isotope. Like most elements, selenium comes in several varieties, which in this case are called isotopes.
