Tables
1 and 2 represent the bone and bone marrow mean doses
and ranges in mRem which were the result of ingesting 706-905 during
the residency interval.
These data were derived from measured urine
activity concentrations during the uptake period.
Constant continu-
ous ingestion of activity was assumed in the models used
to calculate
the dose equivalents and dose equivalent commitments.
Table 3 depicts the external dose equivalent resulting from living on Bikini Island.

assumed living pattern selected.
Since these values were obtained
from ion chamber measurements and hypothetical living patterns,
range of results has been provided.
