SLIDE 28 Ingestion with.meals. (93 wCi) of “~°I An adult male was assumed to take in 3.4 x 106 Bq in order to correspond to urine data. The jRrakes of other iodines and telluriums were based on the relationship between I and these nuclides in Bikini Ash. Meal intake and thus activity intake was modified by body weight for the other members of the population. This modification was based on an exponential relationship between total element intake and body weight which was derived by us from data tabulated in the ICRP Publication Reference Man (ICRP74). Newborns from Rongelap Island were assumed to ingest 850 ml_of breast milk per day (ICRP74) for 3 days past detonation. A fraction of 107> per ml of adult female intake per unit volume of breast milk was assumed to be the fraction of mother's intake of iodine transferred to newborns (Ma81). Decay of the iodine between the time of intake for the mother and the time of intake for the newborn was neglected. Radioiodine excreted from the long-term clearance compartments of the mother's body was considered insignificant relative to radiolodine cleared in the short term (Ma8& 1 ) e ACTIVITY INTAKE BY INGESTION WITH MEALS M Bq Body Weight Rongelap Adult Male 70 Utirik Adult Male Utirik Child 70 30 Rongelap Child Sifo Adult Male Sifo Child 30 _ 70 30 130 85 5.2 3.5 44 30 44 78 20 14 3.0 — — 10 7.0 3.7 2.5 0.74 0.48 3.7 2.5 0.55 0.37 29 i9 21 14 4.4 3.0 0.74 0.48 4.8 3.2 0.89 0.59 30 2.3 20 52 *Normalized to urine excretion result. 14 3.4" 30 2.0
