Relative to human timespans, the half life of plutonium is still pretty long. How long would it take to build up enough decay products to matter?

  A few decades. Those pits are supposed to be pretty pure plutonium. Though it is something like the 'sell by' date on your milk. You open it up and think, is it really gone bad?

    And if you die three weeks later, it was still OK!
