organisms, however, contained high amounts, and the radioactivity of
the whole shrimp samples was approximately two to ten times as high
as that of the wholefish.
Fish also were collected with three of the plankton samples, and
two dolphins (Coryphaena hippurus) were caught by hook and line.
The
gross beta activity of these fish, of a squid, and of a portion of an alga
(Turbinaria ornata*) collected during this period are given in Table 6.
Results of the radiochemical separations and gamma spectrum analyses of some samples
in Table 6, as well as others, are given in Table 7.
