Body and Organ Weights
Data from the Brookhaven National Laboratory!5116 have been
Burmarized to determine the body weight of the Marshallese people.
The
average body weights of the adult males and females are listed in Table
27.
The average adult male body weight is nearly 70 Kg for Bikini and
Uterik which is very nearthe 70 Kg value of reference man.!’
As a
result we have used the body anc organ weight for reference man in our
dose calculations.
90s, Methodology
Bone marrow doses and dose rates are calculated in two steps.
First
the model of Bennett 18119520 is used to correlate the 2°sr concentrations
in diet to that in mineral bone.

Next the dosimetric model developed by

tion in mineral bone.

The calcium content of the normal diet for the
Marshallese is listed in Table 28;
the average intake is 0.7 g per day which
is very similar to the 1.0 g per day estimated for U.S. diets.
