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 dightly 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 other substance agricultural practices on JANET-WILMA without the radiation exposure criteria being exceeded. Similarly, it is difficult to justify limitin: travel to the southerm islands since the ambient gamma levels on the northern islands do not represent a significant external exposure potential for occasional visitation. OptionTIL a. Return to the southern islands (ALVIN-KDITH). b. Substance Agriculture limited to the southem islands plus JAUET-WILY. w except that pandanus and breadfruit are limited to the scuthera island c. Wo restrictions on travel. d. Ro restrictions on fishing. e. Remove Pu contamination on YVONNE,. IRENE and the SALLY burial sites. f. 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 populatio doses weli below the recommended radiation criteria. an ore Soe fee vw
