not account for the estimated activity intake for I-131. In fact lethal exter- nal exposure rates would have to accompany significant radioiodine intakes if inhalation is assumed to be the dominant intake pathway. C. Absorbed Dose For Individuals 1. Total Activity Intake Table 12 was compiled using data from Tables 7, 9 and 11. activity intake and corresponding age were tabulated. Total Newborn babies were assumed to inhale activity at Rongelap and Utirik Islands, no newborns were reported at Sifo Island (Co74). Newborns from Rongelap Island were assumed to ingest 850 ml of breast milk per day (ICRP74) for 3 days past detonation. fraction of 1075 A per ml of adult female breast milk was assumed to be the frac- tion of mother's intake of iodine transferred to the newborn (Ma81). breast milk intake was assumed at Utirik as well. This Decay of the iodines between the time of intake for the mother and the time of intake for the newborn was neglected. Intake of breast milk contaminated with radioiodine from the long- term clearance compartments of the mother's body was considered insignificant relative to the intake from breast milk contaminated with short-term clearance-radioiodine from the mother's body (Ma81). 2. Absorbed Dose per Unit ActivityIntake Table 13 was compiled from data generated by Johnson (Jo82). An exponential interpolation of non-adult values given by Johnson was performed in order to generate the values given here. Thyroid absorbed dose commitment was generated because the nuclides of interest all had halflives much shorter than 50 years, the integration interval used by Johnson to generate 50 year dose equivalents (Jo82). factor of one. Absorbed dose was generated on the assumption of a quality The absorbed dose per unit activity intake values for adults 34
