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.
