is in place, doses to the highest individuals can be compared with
the standard for individuals which is 500 mrem/yr (see Attachments 7
and 8).

Doses for the highest individuals can also be compared with

the Enewetak criterion which is 250 mrem/yr.
Whether annual doses (for the population or for individuals) and
30-year doses for people living on Eneu or Bikini Islands meet or exceed
federal guidance and/or the recently developed Enewetak criteria depends
upon the amount,

kind,

and source of local foods that are eaten,

the

availability of imported foods, the proportion of residence time on
Eneu Island and on Bikini Island,

and the time interval between now

and the date of rehabitation.

Federal guidance and Enewetak criteria
If any particular curve does not go

above the guidance or criteria level; a return of the people could

be accomplished that year without expecting to exceed the guidance
or criteria, providing residence conforms to the conditions upon which
the doses are estimated.

If a curve goes above the guidance or criteria,

the point at which it crosses the guidance or criteria,

as read from

the horizontal axis, is the approximate number of years that return
should be delayed so that

the radiation dose would not be expected

to exceed the guidance or criteria.
