I don't think he actually knew about the decay of the radioactive material bit.
If he thinks he knew why inside of the earth is hot, tell him radioactive decay supplies only part of the heat that is being generated inside the earth, and ask him where the rest is coming from.
In any case, neither major sources of heat generation inside the earth is perpetual. Both will gradually wind down over geological time.
