Coconut - The 1969 values for 90g, and 137 Cs in coconut are in good agreement with 1967 values and Gustafson's intake values would still apply. 0 6. Coconut Crabs - The 1969 levels of both 9 Sr and 137o5 in crabs from Bikini Island are higher than the 1967 average value. Tne edible portion of each crab will contain about 1 pound of muscle and 1 pound of liver. " Therefore, the average radionuclide con- tent for crabs will be the average value for muscle and liver. The level of 2 Fe in crabs is so low (the average value for muscle and liver) as not to constitute any significant intake of this radionuclide for this item of diet. 7. Clams - The levels of POgy 137s, and Fe in clams and lobster are so low that inteke of these radionuclides through these items of diet may be neglected in dose calculations. Table III of this report presents revised values cf daily radionuclide inteke using the Rongelap diet and updated with the 1969 monitoring results.
