SUMMARY OF TASK GROUP RECOMMENDATIONS
ENEWETAK ATOLL
INTRODUCTION
The Atomic Energy Commission agreed to provide radiological
criteria for cleam:ic and rehzbilitation of Enewetak Atoll to the
Department of Defense (DOD) and to the Department of the
Interior (DOI). A comprehensive survey of the radiological
environment of Enewetak was made to serve as a basis for judge-
ments and recommendations.
The survey data show that the northern
islands have the greater amount of radioactive contamination and
there are plutonium problems.
The Directer, Division of Operational Safety, appointed a Task
Group and throughit staff liaison representatives of DNA, DOI
and EPA were kept informed of progress toward completion of
recommendations. Current radiation protection guidance containing
