The islands between Bikini and Eneu are quite small.
Unusually high tides are capable of washing across these low

ons

islands,

and consequently only scrub brush

survives

in the

sand and coral soil.
The four islands were surveyed with G-M counters only.
Several transects were made across each island.
The radiation
levels were quite low and uniform.
Most recorded readings
were ~10 ur/hr.
The range of radiation levels on the four
islands was 3ur/hr to 10 ur/hr (Table 1).

Aerokoj-Eneman Complex

The Aerokoj-Eneman Complex, nine miles west of Eneu, is
a two-mile chain of five islands connected by partly eroded
causeways.
Only the western-most island, Eneman, exhibited
Significant radiation levels.

The two eastern

le radio-_

islands,

Aerokoj

and Aerokojlol are

connected and almost indistinguishable as separate islands.
These two islands were almost completely cleared of vegetation during the testing period.
An aircraft runway ran the
length of the islands.
A water distillation plant and a
personnel housing area were located on the southern side of
Aerokoj.
Some coconut seedlings were found growing quite
well around the former campsite.
The 1slands had isolated
stands of brush, but not nearly the density of vegetation on
Bikini.
The ground was grass covered and was used by a
considerable number of nesting sea birds.
Survey measurements with the scintillation counter and the G-M counter
were made along the center of these islands with spot measurements nearer the ocean and lagoon shores.
Readings were
quite low and uniform, similar to Eneu.
The range of G-M
counter readings was 3 to 10 ur/hr.
The terrestrial gamma
exposure rates measured with the scintillation counter
ranged from only 1 to 3 ur/hr.
Because the radiation levels
were so low on these two islands, no soil samples were
taken.
