~2August 1977, however, three breadfruit trees (10-15 feet in height) were
transplanted to Eneu from Bikini Islands.
will be available to sample soon.
If these trees survive, breadfruit
We will confirm this possibility during
our May 1978 trip to Bikini Atoll.
The concentration of !37Cs in Eneu coconut (data attached) is higher
than predicted using the limited data bank from Enewetak and is higher
than the concentrations used in the dose assessment of Bikini Atoll
(Dose
Assessment at Bikini Atoll, W. L. Robison, W. A. Phillips and C.S. Colsher UCRL 51879 Part 5, 1977).
These recent data are preliminary and additional
results from both Bikini and Eneu Islands will be available in the near
future.
We will then reassess the concentration data, the concentration
ratio data and the resulting dose predictions for Eneu Island.
The results of our radiochemical analyses of ground and cistern
water from Bikini and Eneu Islands collected in 1975 have been published
(Noshkin, Robison, Wong and Eagle, “Evaluation of the Radiological Quality
’ of the Water on Bikini and Eneu Islands in 1975" UCRL 51879 Part 4).
The
water from the wells and cisterns at Bikini and Eneu Islands has been
resampled for analyses twice during 1977.
Our available radionuclide
concentration data for Eneu ground and cistern water is shown in the attached
table.
In addition to continuing our assessment of radionuclide concentrations
in the water, during November 1977, coliform bacteria counts were measured
in the water from several cisterns and groundwater sites.
The results of
this latteranalyses and recommendations were submitted to Dr. William Burr
of DBER in December 1977 (see letter attached).
