For example, 5.le-4 is equal to 5.1 x 1077. C Assumed to be the same as Pandanusfruit. Assumedto be the same as copra meat. We were also unable to collect coconut crabs at all atolls. For atolls other than Rongelap, Utirik, Rongerik, and Ailinginae where coconut crabs were collected at one or several islands, the average radionuclide concentration was used for the entire atoll. When no coconut crabs were found, the radionuclide concentration was determined by using the average value observed at the atolls where coconut crabs were collected because the external gamma measurements and radionuclide concentrations in soil and vegetation were very similar. For Rongelap, Utirik, Rongerik, and Ailinginae, direct measurements or concentration ratios were used. 18 evenspasar ReesMTREt SATE 137 Table 2. Average concentration ratios for
