used will consist of a pair of 4":x 4" NaI detectors and two single
channel analyzers.
A few selected samples will also be screened with
a Ge(Li) system in order to determine their radionuclide content.
,
The Data Evaluations Group will be in charge of co-ordinating
collection of data and samples, sample coding, preparation, counting,
and other activities in this onsite laboratory.
ENIWETOK AQUATIC PROGRAM
The mission of the aquatic survey will be to define the contributing radioactivities in the lagoon and reef areas of the atoll to
assess exposure pathways to individuals utilizing the aquatic environment.
Sources and levels of activity in the lagoon and reef will be
defined using indicator organisms, in-situ detectors, sediment, and
water analyses.
Samples of edible marine vertebrates and invertebrates
will be collected and analyzed for specific radioniclides.
Many species

will be collected from the reef and lagoon areas that were surveyed in
1964,
Changes in activities levels noted over the 8 year period will
be assessed,
Several methods of assessing the residence time of specific
radionuclides in the lagoon environment will be employed.
The types and quantities of samples required will be discussed in the
next sections.
The entire program, covering both survey and food chain
sampling, will be integrated in order to best use our available sampling
facilities.

Program Implementation
The development of the aquatic program in the Eniwetok lagoon was
originally designed to take advantage of facilities offered by the research
vessel, R. V. Palumbo from the Puerto Rico Nuclear Center.
The Palumbo
left PuertoRicoonAugust 20 enroute to San Diego, Hawaii, Kwajalein,
Bikini and Eniwetok.
The mission of the vessel is in support of a DBER
‘funded program involving individuals from the University of Washington,
Lawrence Livermore Laboratory and Puerto Rico Nuclear Center investigating
the biogeochemical behavior of the transuranium elements in a labelled
marine environment.
,
Due to mechanical failures and other operational
problems, the Palumbo has been in the San Diego Naval shipyard since
