Option If a. Return to the southern islands (ALVIN-KEITH). b. Agriculture limited to the southern islands. c. Travel restricted to the southern islands. d. No restrictions on fishing. e. No radiological cleanup. This option (Row A of Tables 1-4) has a zero cost for radiological cleanup that results in population doses well below the guides. It differs from later options in that it leaves the problems of contaminated scrap in many areas of the Atoll, and the Pu in soil on YVONNE, IRENE, and in the burial sites on SALLY, plus generally contaminated areas on ALICE, BELLE, CLARA, and PEARL, unresolved. Such a choice would establish the need for off-limits areas in perpetuity, at least for YVONNE, since the metallic Pu is expected to be nresont on the surface sf the island indefiaiiely unless cleanup is performed. Under current conditions there is a potential for exposures exceeding Federal standards through the inhalation pathway and the possibility of spread of the contamination if access to the island is not controlled. the current quarantine of the island. This accounts for Limiting all agriculture to the southern islands is difficult to justify because some of the northern islands are lightly contaminated. From Tables 1-4, for example, it can be seen that limiting only the growth of pandanus and breadfruit to the southern islands would permit ali other subsistence agricultural practices on JANET-WILMA without the radiation exposure criteria being exceeded. Similarly, it is difficult to justify limiting travel to the southern islands since the ambient gamma levels on the northern islands do not represent a significant external exposure potential for occasional visitation. -20-
