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.
