DOSE CALCULATIONS Aon Bey er a oy 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. Spiers Next the dosimetric model developed by 21 is used to calculate the bone merrow dose rate from the concentra- tion in mineral bone. Bennett's mode! is an empirical model developed from 90¢, concentra- tions in New York and San Francisco foods and autopsy bone samples. concentrations in the diet resulted from world wide fallout. The The model is thought to best reflect the 905, concentration in bone for the low ievels found in the Marshall Islands: it uses as input the actual dietary 305). concentration and the output is the actual 90s; concentration in minera bone determined from analysis of autopsy samples. dependent variations. It also includes age 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. - i Soi i04 30 - The model is a : rhs.
