Option IV a. All of Option III a, c, d, e, and f, plus: . b. Return to JANET and build residences and community center in locations shown on the Master Plan. c. Remove a minimum of 30 cm of soil in all areas where pandanus and breadfruit are to be grown on JANET; import clean soil in which to establish these plants; or import pandanus and breadfruit from the southern islands. ° If these actions proved to be as effective as the theoretical predictions, this would permit return of the Enjebi people to their island. It should be emphasized, however, that even with the above actions, predicted doses are at or above the Task Group criteria for annual exposures and also well above the 30 year gonadal criteria. The levels are expected to be well above those of Option III. 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 90 Sr and 137 Cs are found so far below the surface on JANET. . 4 Importing soil for areas 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 radioactivity levels higher than those in the southern islands. insured is not obvious at this time. -22- How this can be
