Thorium is the #2 contributor to natural background radiation.
It used to be used in those Coleman lantern glass mantles.

I've always heard those were slightly radioactive. One of these days I'm going to get myself a Geiger counter.
I've often wondered why. Is the material they're made out of inherently radioactive or is the thorium added for some particular property it gives?
