Uranium, daughter product and some C-14, depending on source.  I remember
that some western fly ash had interesting levels, and that the calculations
were done for DOE, but I don't recall anything like a risk potential, other
than the academic exercise of confirming that everhing from underground
contained primordial radionuclides.  If my memory is incirrect here I am
certain a downpour of data and corrections will occur rapidly.  Radsafe may
be many things, but it is fast!
