I know nothing about how grinding wheels are made, but I am familiar with
the fact that materials used as abrasives do tend to have elevated levels
of naturally occurring radionuclides - uranium among the rest.  However, I
question the significance of any airborne uranium generated by grinding
operations.  I seem to recall reading somewhere that the energy transferred
to abraded materials during grinding is insufficient to produce respirable
particles to any appreciable degree.

If anyone has better information on this, please correct me.
