The mean correction was approximately 1.02.

quently, we felt no need to correct the remaining 1976 or 1977 data for the
minor energy dependence encountered.

A total of 112 RSS-111 measurements were taken on five atolls.

This is about 1.5 times higher than the cosmic/terrestrial
date rate found on uncontaminated coral islands.
Eniwetak was the island surveyed
in the Rongerik Atoll due to presence of U. S. servicemen at the weather station
there at the time of the BRAVO fallout incident.
Tables 2, 3. 4, 5 and 6 present the raw data from Rongelap Atoll.
surveyed were Kabelle, Naen, Eniaetok and Rongelap.
The islands
Naen is located at the
northwest corner of the atoll, and Kabelle at the northeast corner.
Kabelle is
a significant copra resource; and both of these islands may be used for brief
visits, but neither of them is permanently inhabited.
These islands received a
significant amount of fallout debris and consequently, are still substantially
more contaminated than the islands of Rongelap and Eniaetok, located in the southeast and eastern parts of the atoll.
The current values for external exposure rates
on these islands are listed below and in Table 14.
