Recent developments tn 1978 and 1979 have opened the possibility that islands other than tho
designated in the traditional study may have received variable amounts of radiation, producing a
wide spectrum of long term low level radiation of variable intensity.
Recently obtained information
from the papers of the USS Renshaw seem to indicate that on March 5-6, 1954 that there was a significant increase in background radiation at least on the island of Likiep (7 300mr/hr measured from
the water of the cistern of the Catholic school.

of thyroid and congenital abnormalities in the people of Likiep.
Rongelaa received 175 R of gamma radia-

Alingnae received an unknown amount (approx. 69 R).
Twenty-eight servicemen received
an unknown amount on Rongerik; 158 people on
Utirik received 14 R.

In 1970, Dr. R. A. Conard (then director of the BNL Marshall Island Study) visited Likiep
and attempted to perform a complete survey of the island aimed at detecting the presence of thyroid
nodules by palpation cf all available inhabitants.
During this survey 135 people were examined and
5 nodules were detected,
Of the three major populated islands in the atoll, one was surveyed.
In 1977, a similar survey was carried out on Wotje.
Two of the four inhabited islands in
the atoll were visited.
The visits to Likiep and Wotje were designed to determine the presence
of palpable thyroid nodules in an “unexposed” population.
Current data indicate that this popula-

tion might in fact have had a higher than ambient radiation exposure.

The ex. tsed populations were evacuated
in a period oi +3-72 hours, to Kwajalein, where
they were cared for by a team of radiation
specialists from the AEC and other nuclear labs.
5. The inhabitants of all islands other than Rongelap, Utirik, Alingnae and Rongerik have been
reassured repeatedly that they have not been exposed to "significant" radiation. Recently, Mr.
deBrum designed and circulated a medical questionaire to determine from a number of the people of
Likiep and some surrounding atolls the prevalence of “thyroid” and "congenital" abnormalities since
evaluation of the exposed population, an agesex matched cohort was established for the

by individuals and in many cases, by health care personnel. Interpretation of these questionnaires

do raise the possibility of an unexpected incidence of the aforementioned diseases in Likiep.
