The information obtained from these interviews

is presented in Table 2.

Table

3 lists all individuals whose 137cs body burden exceeded 75% of the maximum
observed 137cg body burden in 1981.
From the interviews it was determined that individuals traveled to Enjebi
Island usually once per month, ate coconut meat and drank coconut milk from
the LLNL garden.

The trips, usually two to three days in length, were made to

collect birds and eggs and were made by members of the population with an age

distribution as listed in Table 4.

Food from the LLNL garden was consumed

during the visit and occasionally coconuts were gathered and brought back to

the southern islands.

While the absolute quantities of food consumed on each

trip, as listed in Table 3, are subject to substantial variation, these
estimates may be helpful in determining reasonable upper and lower limits of
consumption for coconut meat and milk.
The Marshallese were advised in the closeout meeting that a trip to
Enjebi to collect birds and eggs was an acceptable practice but .consumption of
food products grown in the LLNL garden would increase their 137¢5 body
burden.

They were further informed that this exposure to radiation did not

present a health problem but the loss of data would hamper the LLNL efforts to
study the environment of the northern islands.

Since this would affect future

use of the northern islands, the Marshallese promised to refrain from eating
LLNL garden food products.
Information provided during the private interviews led to the collection
of three coconut samples from the LLNL garden.

Gamma spectroscopy results

conducted on the entire coconut (husk, shell, meat and fluid) are reported in

analysis.

These coconuts have been shipped to Bill Robison for detailed
If these 137¢g activity concentrations are representative of

future coconut activity concentrations,

then one could expect to observe

137¢g body burden of 4-7 pCi for individuals ingesting the Robison diet and

residing on Enjebi Island.

humbers with an asterisk indicate that the replicate count was not performed
on the same whole-body counting system as the first count.

The means and

standard deviations reported at the bottom of the page represent results for

the total program and results grouped by the method of replicate counting.
The average capability to reproduce a body burden with either whole-body
counting system is + 7%.

The 2 sigma counting error associated with most
