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 imposes a long-term burden on the Enjebi people which they may find objectionable. Removal of soil alone is another alternative, but the effectiveness of the action is uncertain for reducing population dose since 9055 and 137606 are found so far below the surface on JANET. Importing soil for are: of subsistence crops such as pandanus and breadfruit would possibly reduce the dose from these foods to levels comparable to those found on the southern islands, provided that sufficient soil is imported to encompass the entire root system of the mature trees. The water supply for these crops must not have radio- activity levels higher than those in the southern islands. How this can be insured is not obvious at this time. The Task Group considers Option IV a-c, by itself, to be unacceptable at this time. Even with the actions and restrictions indicated, exposures Tek Grave would be too high to provide an acceptable margin within the criteria. 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 impractical solution to the problem of excessive internal exposure.
