As the program progressed, dose assessment became an important issue,
so our attention focused on the analysis of edible muscle tissue from fish
collected at different locations.
Later our interests shifted to evaluate the
concentrations in muscle among different species collected simultaneously from
the same lagoon location.
As a result, not every tissue and organ separated
from the fish collected over the years were processed
for radionuclide
analysis.
The mean dry/wet weight ratios for the tissues and organs most frequently
analyzed are shown in Table 3.
The dry/wet weight ratios of the stomach
contents are of particular interest, because the differences noted attest to
the different feeding habits of different species.
The percentage that the
organ or tissue was of the whole body fresh weight was also determined for
several species.
These values are given in Table 4.
The ashed samples were transferred to aluminum or plastic containers,
sealed, and analyzed by gamma spectrometry at LLNL using a variety of Ge(Li)diode detector systems.
