CONCLUSION
The principle results of this investigation were that:
1376. and 6520
were major contributors to the committed effective dose equivalent; the overall
body burden pattern was one of initial increase followed by continuous decline
over a period of years; the daily intake pattern was probably one of continuous
decline, this conclusion was based on the fitting of sequential body-burden data
to Eq. 2; the impact of each nuclide on internal committed effective dose equivalent was dependent upon the time between contamination and rehabitation; and the
internal committed effective dose equivalent exceeded external dose equivalent
during the rehabitation period.
The sparse 2395, data indicated further re-
search was necessary in order to estimate accurately the activity intake and com-
mitted effective dose equivalent from this nuclide.
For committed effective dose equivalent, the impact of nuclides with a
short mean residence time in the diet (20, $060) was greater at Utirik because
the population reinhabited within months of the BRAVO event.
