UNCLE (ENIDRIK)
yhe island of Enidrik is located west of Eneman on the southern rim of
the atoll (Figure 8).
The northwest end of the island is heavily
vegetated and showed background radiation levels of 100 to 300 uR/hr
over most of the area.
The central portion of the island consists of coral rubble overgrown
by jpomoea vines and the background radiation levels are generally
19 uR/hr or tess.
Progressing toward the narrow eastern end of the
1stand the vegetative cover remains thin.
Two large sandy areas,
cevoid of vegetation, dominate this end.
Background levels remain
at 10 wR/hr or less over the great majority of the eastern end.
No coconut trees were found on the island.
A few scattered mature
pandanus were seen, and one small grove of immature pandanus was
located on the western end.
One arrowroot sample was taken at tnis
last location where the background was 250 uR/hr.
The
‘'42’Cs concentra-
tion in the arrowroot was 0.2 pCi/g (wet weight) after processing as
previously described.
A soil sample taken in a 300 uR/hr area showed 102Mp,° 137¢5, and ©Co
to be the major gamma emitting contaminants (78%, 14%, and 8% respectively
by concentration).
Only a few pieces of radioactive debris were found and these were
renoved for burtal at sea.
