SUMMARY OF TASK GROUP RECOMMENDATIONS
AQSOOS
ENEWETAK ATOLL
INTRODUCTION
The Atomic Energy Commission agreed to provide radiological
criteria for cleanup and rehabilitation of Enewetak Atoll to the
Department of Defense (DOD) and to the Department of the
Interior (DOI), A comprenensive survey of the radiological
environment of Enewetak was made to serve as a basis for judgements and recommendations. The survey data show that the northern
islands have the greater amount of radioactive contamination and
there are plutonium probiems.
The Director, Division of Operational Safety, appointed a Task
Group and through it staif lieison representatives of DNA, DOI
and EPA were kept informed of progress toward completion ci
recormmendations. Current radiation pretection guidance containing
numerical standerds and radiation proveciion philosophyof nztional
and international standards bodies was used to develop recommended
criteria:
.
.
Population dose to the Enewetak people should be as low as
practicable.
The Federal Rediation Council (FRC) Radiation Protection
Guides (RPG) for individual and gonadal exposures wiil be
used to evaluate expcsure options. The values should be
reduced by 50 percent for individual exposure and 20 percent
for gonadal exposure to allow for uncertainties in dose predictions. The guides for cleanup planning become:
Exposure
Whole body and bone marrow
Thyroid
Bone
Gonads
0.25 Rem/yr
0.75 Rem/yr
0.75 Rem/yr
4 Rem in 30 yr
