Thanks for the heads-up. I have heard about radioactivity issues with rock
phosphate,
particularly the Florida types, possibly Tennessee too, don't know about
the Idaho.
As for quarry dusts, I suppose it may exist, maybe with certain types of
granite (a kind of gravelly rock used for driveways in my region). Radon is
a problem in many areas and sealing cracks and perimeter of ground contact
concrete slabs is necessary; there may be well water issues too.
I'll check tonight to see if my feet and hands are beginning to glow. As
for my use of quarry dusts I feel the benefits far outweigh any risks.
