Lo Stillborn Chicago . and Utah babies analyzed about 0,15-0.2 units (one unit being 1/1000 cf the tolerance ratio of Sr-90 to calcium), about 0,05. Stillborn tabies from India wer New England adults and teeth from adult Londoners were blank. Wisconsin cheeses had a level about ten times that of Chicago babies; European cheeses were a little lower. a Wisconsin alfalfa was 5-20 units, Wisconsin calves 1-2 units.
