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 90 Sr and 137 7 Cs are found so far below the surface on JANIT. . 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: Lio pez ke ee me
