Option IV c describes three ways in which essentially the same end can
theoretically be achieved.
Importation of food is the most dependable action
but this inposes a long-term burden on the Enjebi people which they ray find
objectionable,
Removal of soil alone is anotner alternative, but the
effectiveness of the action is uncertain for reducing population dose since

Importing soil for <
of subsistence crops such es pandanus and breadfruit would possibly reduce the
dose from these foods to levels couparable to those found on the southern islend:
provided that sufficient soil is imported to encompass the entire root svsten
of the mature trees.
The water supply for these crops. must not have radio-
activity levels higher than those in the southerm islands.
How this can be incw
is not obvious at this time.
‘rhe Tasik Group considers Uption Lv usc, vy ilseii, to be Uacceptavic at
this time.
Even with the actions and restrictions indicated, exposures
would be too high to provide an acceptable marpin within the criteris.
This
is especially true for children born at about the time of rehabitation.
Importation of food from the southern part of the atoll or other sources is
believed to represent an inpractical solution to the problem of excessive
internal exposure.
Use of a layer of clean soil in areas for food production
ce
is not known to be effective, would be hard to regulate, and would constitutes
an experiment involving the Enjebi people.
In addition, use of clean soil
for subsistence crops may have little affect on levels of radioactivity in
domestic animals and coconut crabs, which range over the entire island.
Since Option IV a-c is expected to result in population doses near or
slightly above the radiation criteria, further dose reduction may possibiy
be achieved by:
