From the Nuclear Regulatory Commission:
"Because of their highly radioactive fission products, high-level waste and spent fuel must be handled and stored with care. Since the only way radioactive waste finally becomes harmless is through decay, which for high-level wastes can take hundreds of thousands of years, the wastes must be stored and finally disposed of in a way that provides adequate protection of the public for a very long time."

as the half life of most of these materials is well over the average life of a civilisation, and the quantities usually disposed of extremely large, it would be safe to suggest double the half life of the material in question, and then you and your children won't have to worry about it.

they say high level radioactive waste needs to be isolated for 500yrs.
