On the basis of these calculations the normal range of urinary radioiodine excretion at 15 days was estimated to be 0.05 to 0.2% of the peak
thyroid content.
The problem outlined above is a practical application of an analytical
study on the uptake and excretion of iodine in man which will be described
more fully in a UCRL report entitled, "The Dynamics of Iodine in Man."
