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 dose to the population should

not exceed 170 mRem/Yr.

Second, when the dose to individuals

is known, the standard is 500 mRem/Yr.
To comply with this
requirement for 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 pop-

ulation should not exceed 5,000 mRem.
CALCULATED DOSE

The calculation 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.

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.
