Fetal radiation dose estimates were calculated for women who received oral administrations of {sup 59}Fe at Vanderbilt University in the 1940`s. A similar dosimetry analysis was performed by Dyer and Brill in 1972; the availability of recently developed physical models of the pregnant female at different stages of gestation and of a new kinetic model for iron metabolism afforded an opportunity to re-evaluate these doses. Radiation dose estimates for the fetus (and fetal liver in three cases) were calculated for a number of oral and intravenous studies using these new models and the available data about the original experiments. The total fetal doses do not appear to have exceeded a few hundred microgray (a few tens of millirad) for the majority of the study subjects. Considerable uncertainty exists, however, in the amount of activity administered to these subjects. 16 refs., 4 figs., 6 tabs.
