-4It is gratifying that the levels are below those previously reported. Assuming that the average Bikini person spends 85% of their time in the _village and 15% in the interior area the whole body dose would be about the same as the average U. S. citizen receives from natural background, the background level being higher in the United States than on Bikini. A more definitive gamma survey with thermoluminescent dosimeters will be made at Bikini on the next survey. The LCU., The newly acquired LCU immensely improved the survey procedures and living conditions. The ship was clean and freshly painted (quite a contrast to the previous cargo ships used) and the air-conditioned sleeping trailer, clean galley with wholesome foods served and canvas covered afterdeck for eating and lounging greatly improved living conditions even though crowded. The vessel was Slow. For instance, only an average of 4.8 knots were made between Kwajalein and Utirik (about 240 miles) hitting into the winds and waves. Beaching the vessel was a distinct advantage allowing easy access for people coming aboard for whole body counts and for moving equipment back and forth. On my return from the islands, I attended a meeting held at the University of Hawaii, Marine Biology Laboratory, at Coconut Island. LCU alterations for improved specialized operations and scheduling of the vessel] were discussed. It is obvious that from the number of people who want to use the vessel that supervised prior scheduling of the vessel will be necessary. ~ “A , oan oe Ee aay be owcaA eo Robert A. Conard, M. D.
