Jelete is similar in almost all respects to Lukoj.
The
radiation survey was accomplished by encircling the island
about 100 ft. inland.
Readings with the G-M counter ranged
from 63 to 130 ur/hr.
No soil samples were obtained.

Oroken - Bokaetoktok —- Bokdrolul
These small islands, the most westerly of the southwest
group, exhibited similar general characteristics - black
coral rock shores, dense vegetation, mcist. highly organic
soil, and quite large bird populations.
The islands were
essentially undisturbed by construction and other similar
activities connected with the testing operations.
Radiation levels on these islands were somewhat lower
than on Lukoj and Jelete.
On Oroken the measurements arcund
the island about 50 ft. inland ranged from 17 to 30 Lr/hr.
Closer to the center of the island the levels were around
40 ur/hr.
The highest level measured with the G-M counter
was 43 wr/hr.
On Bokaetoktok the levels were oniy slightly lower,
ranging from 10 to 23 ur/hr with a maximum of 30 ux/hr near
the center.
On Bokdrolul fairly uniform readings of from 24 to 36
ur/hr were recorded with the scintillation counter.
A
similar range was found with the G-M counter with one measure-
ment of 50 ur/hr,
Lower levels of about 10 ur/hr were
typical near the ocean or lagoon shores.
