show a significant change.

The Woy value is higher by a

factor of about 14 but the 13Tos value is lower by a factor
of 150.

These new values should be used. in a redetermination

of internal exposures from 90, and 13T¢5,

Coconut - The 1969 values for 7°sr and 137s in coconut are
in good agreement with 1957 values and Gustafson's intake
values would still apply.

Coconut Crabs - The 1969 levels of both 7°sr ana 23%cs in crabs
from Bikini Island are higher‘than the 1967 averege value.

The

edible portion of each crab will contain about 1 pound of muscl
and 1 pound of liver.

Therefore, the average radionuclide con-

tent for crabs will be the average value for musele and liver.
The level of >> 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.

|

Clams - The levels of 90sy 13765, and Fe in clams and lobster
are so low that intake of these radionuclides through these items
' of diet may be neglected in dose calculations.
Table III of this report presents revised values of daily radionuclide
inteke using the Rongelap diet and updated with the 1969 monitoring results.
