relevant to the Eniwetok program is to emphasize the similarity in the

could elaborate on second-order differences as they exist or as they are
to be expected, but it is most important to point out two major considerations:
1.
Regarding the major pathways, evaluation can be based primarily upon
the expected similarity which will exist in Lifestyle and habits
between the returning Bikinians and Eniwetokese.
The predominant
protein source will be from marine fish, but, where possible, coconuts,
pandanas, and arrowroot will be cultivated for food.
constructed on the basis of the Rongalese diet,
A diet can be
as was done by
Gustafson for Bikinians, and adjusted as indicated by information
gained on the specifics of Eniwetok Atoll.
2,
Serious contrast can be made, however, between Eniwetok Atoll and Bikini
Atoll as regards the base radiological contamination, which is both
larger for Eniwetok and compounded by the larger amounts of e395, and
other transuranics.
Thus, while we cannot yet speak of the relative
importance of long-lived fission products,
alpha radioactive elements,
activation products, or
it will be necessary to provide comprehensive
assessment of the latter class of radionuclides in order to put these in
perspective to the others.
This will include assessment of both the in-
halation and ingestion pathways.
In brief, the assessment is organized around a pathway-dose two dimensional
matrix,
Radionuclide composition of dose transfer media such as foods, air, and
water will be coupled with existing models of intake and metabolism to calculate
potential dosages, taking into consideration the projected patterns of living
of the future inhabitants,
The major pathways under consideration are:
1.
External Radiation
2,
Internal Radiation
3.
@,
Terrestrial Foods
b.
Marine Foods
ce.
Water
Inhalation, Submersion
An understanding of the data base to be generated for these assessments
can be obtained in the following sectizns of this program plan.
It is our
goal to provide all the data needed to order the relative importance of
