Diet and Lifestyle Study
All avatlable reports concerning fallouc on Allinginaew, Rongelap,
Rongerik and Utirik have been examined and pertinent {ufurmation
has been collated into one location.
The data collected concerns
external radiation measurements, radionuclide concentrations in
soil, water, vegetation, animals and food items. In addition,
efforts are being made to collect information on whole body
analysis and bioassay samples.
b.
A recent diet and lifestyle study completed in November 1978 will
provide a firm basis to estinate internal and external doses.
1297 study
Historic samples collected by University of Washington during the
period 1954-1974 have been analyzed for 1291 (Table 4).
samples are also being analyzed for 99T¢,
These
Information from Item 8
(Methods of Scudy) will be required to correlate the findings.
Additional samples from these areas (Rongelap, Ronerik, Utirik)
will be analysed for 129] and 99Te if required.
In addition, we
are exploring the possibility of analyzing "Bikini-ash"-the fallout
that settled on "The Lucky Dragon".
This sample should provide the
most accurate description of the fallout.
‘State-of-the-Art’ Computer Siwulation
a.
All available data percaining to meteorological conditions before,
during and after the BRAVO test have been collected and transmitted
to Lawrence Livermore Laboratory for the computer analysis. These
results should be available by February/March 1979.
A recent Marshall Islands Radiological survey completed in
December 1978 should provide iso-dose lines for recent times.
Com-
parison of the two plots should be very valuable in assessing 1954
observations.
Discussions are being continued with the scientists and technical people who
were involved during Operation Castle.
