To what extent, if any, is the assumed diet realistic or conservative?
After what period of time is it anticipated that this diet will, in fact, be
available as the primary, if not sole, source of food?

For example, are the

people now to some extent dependent upon imported food, and would this continue?

How do LLL soil surface (0-3 cm) measurements compare with EPA recommentations (0-1 cm)?

(Perhaps information related to this could be obtained

from the Rockwell comparative soil sampling program at Rocky Flats.)
How reliable and consistent is the Pu:Am ratio of 2:1?

Is it justifiable

to assume a 2:1 ratio for both the surface soil (0-3 cm) and the root zone
(0-30 cm)?
How realistic are the occupancy factors stated?
for women and children?

Are these valid also

For example, children might be expected to spend

more time on a village or picnic island, but would their estimated dose be
decreased because of avoidance of agricultural islands, increased because
they might be expected to play in the dirt, sand or coral, or would the dose
be essentially the same as for an adult?

A gut transfer factor of 3.0 x 10" may not be conservative.

EPA

recommends 10— 4 for Pu-239, 240 oxide, 1073 for oxides and non-oxides of

other isotopes of Pu, Am and Cm, and 5 x 10° 3 for biologically incorporated
material.

Use of 10 3 for Am is okay, but Pu-239, to say nothing of Pu-238,

absorption factors may have been undérestimated.
This subject is one in which numbers are given in the report, but little
is said about the experimental conditions or the applicability of the numbers
to the Eniwetok dose assessments:
a) Pu in chlorinated water may not remain as +6 in physiological milieu.
b) Reference to Stuart is not given.
