Why would you want to keep it apart for millennia?
If its highly radioactive it decays away quickly.
If it doesn't decay away quickly its not very radioactive.

Its simple physics.

No it's not.
Some materials remain dangerous after 100,000 years.


So which ones are highly radioactive after 100,000 years then?
