-2In reviewing the data it should be noted that where average values are given, these are arithmetic means and conservative values. The true mean is less than the arithmetic mean, since the distribution of radiological values is either Poisson or logarithmetic. Also it should be noted that some values are in terms of wet weights and others, dry weights. (For some samples wet weights are difficult to determine reliably). Wet to dry ratios for various types of samples are of the order of 4 to 10. Also, the average value such as given in (4) and the inherent errors associated with lumping things together without consideration for the errors within or between species and within or between areas. The table of survey meter readings (1) lists maximum and average values at ground levels and at three feet above the ground, and for gamma and beta-gamma combined. The maximum value was 21 mr/hr for beta-gamma at ground level for an area about ten feet in diameter (not a crater) on Rumurikku Island. In my conversation with Dr. Dunham I commented that perhaps levels of radiation in a few small areas might require the establishment of exclusion areas, but upon looking at the other information from this area, this conclusion may not have been justified. The table of 299sr values (3) does not list coconut crabs. Only one coconut crab was captured at Bikini in 1964 and the analyses of samples from this speciman were not completed before preparation of the table. The 9[%sr and 137cs values are as follows: Shell Muscle 90sr 137¢5 in pci/g (dry) 2200 (600 est.) 192 940 Liver 135 The analyses of the muscle sample for 20sr is in process, but based upon the ratio of 290sr in shell and muscle of Coenobita, a closely related crab, and in coconut crabs from Rongelap, a value of 600 pCi/g(dry) has been estimated. As you recall, coconut crab was the only food item forbidden to the Rongelapese when they return to their home island. The values for radionuclides in soils that you asked for are given in Table (5). These are values for the gamma~-emitting radionuclides. These samples have not been analyzed for plutonium, Todate, our plutonium analyses have been limited to Johnston Atoll samples.
