CLEANUP OF BiKINI ATOLL
By memo of February 24, 1971% to the Commission through the General
Manager, the report entitled, "Summary Report of the 1969 and 1970
Bikini Surveys," NVO-97, rebruary 1971, was provided for your information. Tnis summary report was to be followed by detailed reports
by the Southwestern Radiological Heaith Laboratory (SWRHL), Environmental Protection Agency, and by the Nevada Operations Office. These
recorts are now provided to the Commission for information prior to
tneéir release. Tney are titied:

“Report of the Radiological Cieanup of Bikini
Atoll,” SWRHL-ilir, March 1971.
"Radiologicai Resurvey of Animals, Soils and
Groundwater at Bikini Atoii, 1969-1970,"
NVO-269-8 (Rev.).
The SWRHL-liir report concludes that sampling of food items growing
on the atoil in 1969 indicate mean concentrations of 137Cs and 9°Sr,
which are essentiaiiy in agreement with those obtained in 1967 (the
1967 data were used in determining that the Bikini people could be
returned to their homes).
internal dose estimates have been performed
by Gustafson ‘/ utilizing the 1967 data and would appear to be valid
for the 1959 data as well.
Results of the 1970 survey for plutonium
in the air are approximately two orders of magnitude below the FRC's
guide for an individual in the population and would not significantly
affect tnese estimates. The projected whole-body dose for a person
born on Bikini in 1970 and living tnere for 70 years would be less
than 10 Rad.
