Uranium in urine

["Eric L. Darois" <daroiel@naesco.com>]

     I am looking for uranium concentrations in urine from natural sources. 
     I expect the range is large and may be very dependent on diet.
     
     Sources of information or specific data would be greatly appreciated.
     
     Please return info to me at:
