The 9 Sr value is higher ty a
137 Cs value is lower by a factor
These new values should be used in a redetermination
of internal exposures from 905, and 13%os,

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.

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.
