However, it was reported that
the 2zaximum dody Durden was three times greater than the mean value for population subgroups (adult males, adulc females,
female children etc.) and the maxi-
mum daily activity ingestion rate was 5 times the mean value for population
Conse-
subgroups for Rongelap, Utirik and 3ikini measured data (GrS0, Led0).
quently,
the extreme values for body mass and milx ingestion rate which
leads toa
a maximum body burden of 13 times the mean and a maximum dose equivalence of 13
times the mean are noc consistent with observations in the field.
As stated earlier, a review of the Rongelap daily activity ingestion rate
data (Le80) indicates that the population ages 0 to 4 years, (mean age 2 years)
had an average 13765 ingestion rate which was Larger than the adult ingestion
a
rate by a factor of 2.
From the 3ikini data presented in table 4, this seems
possible only if other dietary items are used as a food source for the
Marshallese child.
For the infant, several sources (Na8l, Wi4l, Mu54, and Ba77)
indicate that natural food supplaments are frequently given.
Furthermore,
Bayliss - Smith (3a77) suggests that weaning takes place in Pacific cultures between 6 and 12 months of age.

Small children drinking fluid from 2 to 3 coconuts each day could have achieved
this level of intake.
Thus it seems reasonable to assume that the infant's diet
consists of human milk and coconut by-products in varying proportions during the
first year of life and that the dose estimates should be adjusted upward in pro-
portion to the increased activity ingestion rate that is postulated.
