Teconnical ?rcearess cone.

ash” the fallouc aaterfal thac sertled on the Japanese fishing vessel.

These

samples should provide che nost accurate characterization of the fallout.
Prelinimary computer siqulations of fallout transporcation and deposition have been conm~
oleced.
Daca analysis of tne recenc diet and life style study has been completed.
Discussion witn scientists and technical people who were involved with the 3RAVO
test is being continued.
Analysis of the Marshallese ceecth samples for Pu isotopes
is

in progress.

Expected Proeress in BY-2 (FY 1980),
A final report on the diet and life style for the Marshallese will be com
dleced.
The compucer simulacion of fallout will also be completed.
Thyrotd glands
trom the exposed Marshallese will be analyzed for 99to and 1491,
Analysis of

the “Bikini-ash"” will be done as soon as we get an aliquot of the sample.

[ce is

also expected thac data on the exposed Japanese fishermen will be made available at
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
tne validity of the mocels used.

to test

Expected Progress in 3Y-1 (1981).
Final dose estimates cto the exposed inhabitants of Uciritk and Rongelap shouid

te complered.

The methodology developed will be extended to Liktap and other

islands which were on the “fringe” of the fallout pattern.

Future Accomplishments.

The cechniques and expertise developed in the course of this study could be
used to reassess doses to population in other areas subjected to exposure from

tallouc or even chose resulcing from occupational situations in the past.

2Oh.

Relationship to Other Proiectg.

a.

This study will help establish dose estimates from the time of the inci-

dent to the present, and will complemenc che aerial survey for external radfation
measurements, over these islands, which has been completed.
Together they should

oresenc a reliable picture of doses received by che populations and also enable

dose estimates to be projected into the fucure.

b.
This study will be in close conjunction with the BNL Radiological Safety
Program in the Marshall Islands (HA~O2-01-02-0) and with related programs of the
3NL Medical Department (HA-O02-91-01-0),
Coneinued collaboracion with the University of Washington, Laboratory of Radiation Ecology, and the Bacrelle Pacific
Nortnwese Laboratory will be maintained in the area of sample analysis and data
{nterpretaction.
