a/ fhe table's data were supplied by Dr. E. T. Lessard of the Brookhaven
National Laboratory. I have used the Moss factors (Moss, 1988).
b/ The intake can be calculated by dividing the urinary excretion by the
factors given. For example, after 20 years of intake, the daily
excretion is found to be 3 x 10-5 picocuries. Then the intake is:
(3 x 10-5)/ 2.3 x 10-4 = .13 picocuries/day.
