Pile all the nuclear waste at ground zero of one of the nuclear weapons test sites. We are assured by anti-nuke activists that such sites are hopelessly contaminated forever already.
Build a chain-link fence around the site.
Post signs in multiple languages on the fence: "If you cross this fence you will die."
From time to time, somebody will cross the fence and die. Average intelligence of humanity increases by some minuscule amount. Evolution in action.
(Alternative plan: use nuclear waste to mint actual money. Advantages: Objectionable rich people are punished. Currency incentivized to circulate, boosting the economy. Foreign aid delivered by ICBM...)
