However, it is believed that any individual will not exceed a
daily intake, averaged over a year, greater than two times

the estimated average daily intake.-

(See Enclosure 1.)

FEDERAL STANDARDS
To comply with Federal Radiation Standards, certain conditions
must be met.
First, the average whole body dose to the population should not exceed 170 mRem/Yr.
Second, when the dose to
individuals is known,

the whole body standard is

500 mRem/Yr.

To comply with this requirement fer Bikini Island residents
the monitoring program to measure the dose to individuals was
begun five years ago.
Third, the dose to bone marrow of individuals should not exceed 500 mRem/Yr.

Because of the way

certain radionuclides are deposited in the body, bone marrow
doses are expected to be higher than whole body doses.
Thus,
the bone marrow standard for individuals will probably be controlling at Bikini Atoll.
Fourth, the average whole body dose
over 30 years to the population should not exceed 5,000 mRem.
CALCULATED DOSE
The calculated doses shown below are for two living patterns
and for two assumed diets.
The diets are based on the recent
experience and observations of the scientific teams who have
been working on Bikini Atoll.
Calculated Maximum Annual Dose

A.

(Average for Population )

People live 100% of the time on Eneu Island.
With Food Imports

Without Food Imports

Whole Body

120 mRem/Yr,

210 mRem/Yr.

Bone Marrow

140 mRem/Yr.

260 mRem/Yr.

B.

People live 80% of the time on Eneu Island and visit

Bikini Island 20% of the time, but assumes no food
from Bikini Island is eaten.
With Food

Imports

Without Food Imports

Whole Body

170 mRem/Yr.

260 mRem/Yr.

Bone Marrow

190 mRem/Yr.

°300 mRem/Yr.
