This
specimen is the only one in which wi85 was detected with
certainty within tissues of an organism.
In general,
the levels of wi85 in samples from the
islands of Eniwetok Atoll reflected the pattern of distribution found at the plankton stations.
Thus,
the island
(Belle) northwest of the target area (near Janet Island)
had very high levels of wiSd |
The islands south (Vera) and
southwest (Henry, Keith, and Leroy) of the target area had
lower levels of the isotope.
Ujelang Atoll
The wi85 contamination on the plant leaves and in the
soil at Ujelang Atoll, collected July 19, 1958, was low in
comparison with that at Eniwetok,
and Keith Islands,
with the exception of Leroy
where low levels of wi8s5 were observed also.
