Dear Henry:
’
Please find tabulated below the urinary excretion rates (d‘') per unit intake rate (d‘) for
continuous ingestion of Pu. For example the values represent the pCi/d excreted in urine
per pCi/d ingested. The excretion rates are based on the soluble form (f, = 10°) and the
urinary excretion function tabulated by Leggett and Eckerman (Health Phys. 52, 3, 337-346,
1987). This excretion function is consistent with all source of information on Pu excretion.
