Technical Progress cont.
ash” che fallout material thace settled on the Japanese fishing vessel,
These
samples should provide the most accurate characterization of the fallout.
Prelininary compucer sigulations of fallout transportation and deposition have been conmoleced.
Daca analysis of the recent diet and life style study has been completed.
Discussion with scientists and technical people who were involved with the BRAVO
tesce is being continued.
Analysis of the Marshallese teeth samples for Pu {isotopes
is
in progress.
Expected Proeress in BY-2 (FY 1980).
A Final report on the diet and life scyle for the Marshallese will be completed.
The compucer simulation of fallout will also be completed.
Thyroid glands
from the exposed Marshallese will be analyzed for 99Tc and 129T,
Analysis of
the “Bikini-ash” will be done as soon as we get an aliquot of the sample.
It is
also expected that data on the exposed Japanese fishermen will be made avatilable ac
chac
cime.
Preliminary analysis of
the data generated
so far will be made using
existing models.
The results will be extrapolated to presenc times so as to test
the validity of the models used.
Expected Progress in BY-1 (1981),
Final dose estimates to che exposed inhabitants of Utirik and Rongelap should
se completed. The methodology developed will be extended to Likiap and other
islands which were on the “fringe” of the fallour pattern.

Future Accomolishments.
The cechniques and expertise developed in the course of this study could be
used Co reassess doses to population in ocher areas subjected to exposure from
zallouc or even those resulting from occupational situations in the past.

Relationship to Other Projects.
a.
This study will help establish dose estimates from the time of the inci-
b.
This study will be in close conjunction with che BNL Radiological Safety
dent to the present, and will complement the aerial survey for external radiation
measuremencs, over these islands, which has been completed. Together they should
present a reliable piccure of doses received by the populations and also enable
dose estimates to be projected into the future.
Program in the Marshall Islands (HA-02-01-02-0) and with related programs of the
3NL Medical Department (HA~02-01-01-0).
Continued collaboracion with the University of Washington, Laboratory of Radiation Ecology, and the Batrelle Pacific
Northwest Laboratory will be maintained in the area of sample analysis and data
interpretacion.
