~4Consumption of the cistern water would result in lower 10, 30, 50
and 70 year integral doses than those computed for the consumption of
Bikini cistern water in UCRL-51879, Part 5.
The average concentrations
in the water at FWR 4 will result in a slightly lower dose from !37Cs and
239+240PU and a higher 2°Sr dose than computed for consumption of Bikini
Island cistern water in UCRL-51879 Part 5.
A number of the reef fish, mullet, were collected for radionuclide
analysis from six different islands of Bikini Atoll, including Eneu, during
1977.
Concentrations of specific radionuclides have been determined in the
fish flesh, bones, skin, viscera, reproductive organs, gills and stomach
' contents.
The radionuclide concentrations are used to compute the radiological
exposure to individuals from ingestion of marine foods.
Mullet from Bikini
have higher !37Cs levels associated with muscle tissue than average values
found for Enewetak Atoll fish.
The mean ®°Co levels in muscle tissue of
fish from both Atolls is similar and the highest concentrations are
associated with reproductive organs.
;
Plutonium concentrations in mullet
from Bikini differ from those at Enewetak but. the average concentration
factor for plutonium in fish muscle is similar at both Atolls.
The
concentrations of specific radionuclides in mullet tissue vary greatly
from island to island within the Atoll and the radionuclide concentrations
in the fish caught off Eneu fall between the lowest and highest values detected
in mullet at Bikini Atoll.
at Bikini is in progress.
