Contamination from radioiodine in perspiration

     Ben:
     
     ICRP Pub. 23 on Reference Man 9(pp 386-387) gives the following
        Intake 
                in food and fluids=200 ug/d, 
                in air 0.5-35 ug/d
     
        Losses
                in urine= 170 ug/d
                in feces= 20 ug/d
                in sweat= 6 ug/d
                in hair = 2.3 ug/d
     
     You can see there will always be contamination 'problems' at 
     therapeutic doses of I-131.
     
     Hope this helps
