team. In July 1957, after careful evaluation of
radioactive contamination, Rongelap Island was
considered safe for habitation. A new village was
constructed, and the Rongelap people were moved
there by Navyship. (See frontispiece.)
The annualsurveys are carried out at Rongelap
and also at Kwajalein and Majuro Atolls, where
a number of Rongelap and Utirik people now
reside. Examinations on Utirik Atoll are carried
out about once every 3 years.
A group of more than 100 Rongelap people,
whowererelatives of the exposed people but had
been away from theisland at the time of the ac-
=
cident, moved back with the exposed people to
their home island and have served as an ideal
comparison population for the studies. The number has since increased to >200.
Since the accumulation of data from these surveys is becoming increasingly voluminous, survey
reports published by this Laboratory are made as
complcte as possible and include a considerabie
amount of raw data, much of it in appendices, so
that others may have access to complete data.
A summary of early andlate findings covering
the entire 15-year period is presented at the end
of this report.
