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 Navy ship. (See frontispiece.)
The annual surveys are carried out at Rongelap
and also at Kwajalein and MajuroAtolls, 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,
whowere relatives 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 accumulationof data from these surveys is becoming Increasingly voluminous, survey
reports published by this Laboratory are made as
complete as possible and include a considerable
amount of raw data, muchofit in appendices, so
that others may have access to complete data.
A summary of early and late findings covering
the entire 15-year period is presented at the end
of this report.
