SLIDE 51 and 52 Body burden and excreta measurements. The body burdens which were measured directly had a standard g¢gviation of + 30% of the mean value for adults. The maximum body burden of Cs was observed to be 3 times the mean value. Indirect measure of body burden by uringanalyses resulted in greater variation. The standard deviation for Sr was + 60% of the mean value for adults. The standard error for the adult mean body burden was 5 times less than the standard deviation because many adults participated during each mission.
