Table 3 depicts the net external dose equivalent
resulting from living on Bikini Island. The dose
equivalent during the residency interval varies for
subgroups within the population acording to the
assumed living pattern selected. Since these values
were obtained from ion chamber measurements
and hypothetical living patterns, no range of
results has been provided. [n this report, !

1974, 1977 and 1978. Constant continuous uptake
of '"Cs in the diet was not assumed. For these
calculations, the uptake period was divided into
three intervals during which the ‘Cs activity in-
gestion rate for a given interval remained constant,
but increased stepwise with time to account for
observed increases in '’Cs body burdens.
