near to the west,

Lele,

are so small as to be little more

than wide spots on the causeway.

There were some tidal

pools in low depressions on these islands which contained
mullet and milkfish.
The vegetation was primarily scaevcla.
Radiation levels along the causeway and on these small
islands were low and uniform - 6 to 8 jtr/hr measured with
the scintillation counter and 10 pr/hr with the G-M counter.

Some pieces of metal scrap found along the long causeway
gave higher readings.
Samples analyzed with the spectrometer

on the ship showed the contamination to be mostly 6° Go.
The western-most island of the complex,

largest in extent.

Eneman,

is

The vegetation was quite thick around

the tower on the eastern end, becoming less dense near the
center and western end.
The western end was, in fact, quite

desolate, with low depressions of moist sandy scil covered

with black algae.
Concrete blocks off the end of the island
mark the ground zero for the testing cf several devices.
Extreme variations in radiation levels were found on Eneman.
The eastern end was similar to the rest cf the complex - 1

to 10 ur/hr.

Beyond the center part of the island toward

the western end, however, levels ranged from 20 to 60 uxr/hr.
The areas surrounding the sand craters on the western end
were also within this range.
The craters themselves (the

algae covered sand depressions very near the blast area}
were quite hot — from i100 to over 500 ur/hr.
The highest
level measured on the whole atoll was in this area on

western Eneman - 570 ur/hr measured with the scintillation
counter.
Soil samples were taken from two locations on Eneman
where these high radiation levels were recorded.
Analysis
of these samples indicated primarily *°co activity with

considerable **®sb, *®° Bu, and *°?™Rh activity.

*®*Eu,

+°SRh, and ***am activity was also seen in the Ge(Li)
spectra.
There was relatively little *8"cs activity.
