This
specimen is the only one in which wi8s5 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 wi85 |
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,

and Keith Islands, where low levels of wi85 were observed also.
The ratio of wi85 to the other gamma-emitting isotopes in the

Thus in Scaevola and Messerschmidia leaves at
Belle Island (Eniwetok Atoll) for which the disintegration
rates were corrected to July 19, wi85 contributed 66 per cent
