Dear RadSafers,

Maybe some of you might be able to help my former colleague on this matter.

Many thanks in advance.

Hi,

   At the moment I am investigating the amount of radioactivity in a batch
   of sandpaper. I am looking for references on this subject (preferably
   containing activity concentrations of the natural occurring
   radionuclides Th-232, U-238 and daughters). So far these references are
   hard to find.

   Can anybody help me with this?

   With friendly greetings, GJ
