The calculated radiation exposure levels for people living only on Enewetak,
Medren and Japtan islands are:
LS ,
Maximum Individual
with Imported food
without imported food
20-Years
11 Mtl lirem/Year
190 Mi711rem-Bon
24 Mflltrem/Year
220 Millirem-Bone Marrow
120 Mfllirem-Whole Body
mY

mH
Millirem-whole Body
If it 1s assumed that 15% of their time is spent on the northern islands,
and that 10% of their total intake of coconut meat/miik originates from the coconut
trees of the noftheastern islands, the calculated radiation exposure levels are:
Maximum Indtvidual
30-Years
with imported food
28 Millirem/Year
.
250 Millirem-Bone Marrow
200 Millirem-Whole Body
without imported food
5) Millirem/Year
460 Millirem-Bone Marrow
270 Millirem-Whole Body
For purposes of reference, it may be recalled that U.S. exposure criterfa are:
Maximum exposure to an individual {mn any one year:
Integrated 30-Year exposure level:
99Soe...
5000 Millerem
Because of the uncertainties and assumptions which are inherent 1n deriving
radiation exposure estimates of this nature, the Atomic Energy Commission Task Group
report recommended the following exposure limits for planning and cleanup nurnoses
Maximum exposure to an Individual in any one year:
250 Millirem
Tnitegrated 30-Year exposure level: 4000 Millirem
Given the assumptions and limitations stated, it {is apparent that all of the
radiation exposure valuesare compatible with both the U.S. Exposure Guidance and
the AEC Recommendations.
I hope that this information is helpful to you and responsive to your request.
