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 ts difficult to justify because some of the northern islands are lishtly 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 all s ne other,substemeer 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. Option III a. b. Return to the southern islands (ALVIN-KELTH) . D yest ont Ae Sabatance Agriculture limited to the southern islands plus JANET-WILMA except that pandanus and breadfruit are limited to the southem islands. c. No restrictions on travel. d. No restrictions on fishing. e. Remove Pu contamination on YVONNE, IRENE and the SALLY burial sites. £. Remove radioactive scrap. This is one of the less expensive options in that it requires removal of only the most seriously contaminated materials. In practical terms, it maximizes unrestricted use of areas of the atoll having low radioactivity levels, leaves no hazardous legacies for the indefinite future, and permits living patterns which, with high confidence, are expected to result in population doses well below the recommended radiation criteria. 020
