For the special calculation made for children born at the time of ‘ return for the Enjebi (Janet) Island living pattern, the 30 y integral Bg te 4am Jes . ! Net fed ype Pr AS) ‘ wholebody and bone marrow doses for normal conditions are 4.2 rem and 4.7 rem respectively (Table 43). For the adult case given in Table 30 the results were 4.9 rem and 5.5 rem. For famine conditions the 30 y integral doses for children are again less than those estimated for adults. The doses for the scenario where the child is born 8 years after return (Table 44) are less than when the child is born at the time of return. The estimated arithmetic mean, X%, of the radionuclide concentrations “in soil and foods is used to estimate a dose that, about 65 percent (range, for our data, includes 55 to 75 percent) of samples with equal or lower radionuclide concentrations. Other doses can-be estimated from prob- ability plots giving cumulative concentration quantities (for example, Fig. 4). The s7! (s = standard deviation of a log-transformed plot) is the slope of this log-probability plot .34 By using the slope of the best fitting line, we can estimate the proportion of concentrations that are less than x, 2®, and 3x; or 90, 95, and 99 percent cumulative probabilities. Experience with concentrations in soil and air, 35,36 which often follow multiplicative models, yield measured concentrations that have an approximately lognorme! probability density. If we refer again to the log-probability plots (Figs. 4 through 10), our otherwise right-skewed untransformed data approximately fit a straight line, and we see at least qualitative evidence for assuming the probability distribution is lognormal.
