Re: Monozite Sand

["William CTR Kolb"<William.CTR.Kolb@faa.gov>]

     Monazite contains from 3 to 9 percent thorium oxide. Small amounts of 
     uranium are often associated with monazite deposits, as are trace 
     quantities of the rare earth elements gadolinium, lanthanum, lutetium, 
     neodymium, and samarium--all of which have naturally occuring 
     radioactive isotopes.

I am looking for information on concentrations of radioactive material 
in monozite sand. Any help would be appreciated.
     
Thanks
