Nuclear waste, for example, remains radioactive for eons. But after about 3000-20000 years (depending on the type of reactor) nuclear waste is only as radioactive as naturally occurring uranium ore. The rule for nuclear explosions is 7 times 7 times 7. After 7 hours, 90% of the radioactivity is gone.
