Essentially all of cleanup can be accomplished by personnel
categorized as occasionally exposed individuals; accordingly,
the majority
of the workforce will be treated as such insofar as radiation limits are
concerned.
If, on the other hand, radiation areas
(See IV’ G.4) should
be established, they will be assigned to personnel having the most experience

Plutonium represents the greatest radiation hazard facing
Cleanup workers.
Although plutonium at Enewetak is harmless while it
remains outside the body,
enters the body.
it could cause deleterious effects if it
Precautions will be taken to prevent the inhalation or
ingestion of plutonium,
but a bioassay program will be prescribed to
monitor the effectiveness of the precautions.
