considering the desires of the dri-Enewetak, the Task Group Re
recommended a living pattern which would not actually require
cleanup. Key features ofthis living pattern were that:
a. Residence and agriculture (except coconuts) would be restricte
southernislands.
b. Coconuts could be grown on northeastislands for subsistence
commercial purposes.
c. Fishing could be conducted anywhere.
d. Any island except Runit could be visited.
Minimum cleanup recommendations were offered to provide be
assurance that the dose for the recommendedliving pattern woulc
minimized. These recommendations werethat:
a. All radioactive scrap metal be removed.
b. Contaminated debris in ‘‘burial sites’” be removed.
c. Runit be quarantined until plutonium contamination thereon
removed.
d. Plutonium contamination on Runit and Bokenbe removed.
