A half life is still thousands of years.
For which radioactive isotope?
https://en.wikipedia.org/wiki/List_of_radioactive_nuclides_by_half-lifeEdit: "The main wastes arising during the operation of a
nuclear power plant are components which are removed
during refuelling or maintenance (mainly activated
solids, e.g. stainless steel containing cobalt-60 and
nickel-63) or operational wastes such as radioactive
liquids, filters, and ion-exchange resins which are con-
taminated with fission products from circuits containing
liquid coolant."
ibidCobalt-60 half life 5 years
Nickel-63 half lihe 100 years.
