11. A comprehensive air sampling program should be conducted over a period
of 12 consecutive monthsunder conditions closely approximating
human habitation and expected soil disturbance.
This would add to
the body of available information on radioactivity levels in air.
This. programcould be conducted coincident with and in\ SUppOre of
cleanup operations.
12. Base~line surveys of body burdens and urine content of 13764 and
90
Sr should be made for the Enewetak people prior to return to
EnewetakAtoll, after the first year of residence, and as appropriate
thereafter.
Resurveys of the environmental radiation and radioactivity
levels should be made starting in the first year of return and
repeated every other- year.
To be determined is the adequacy of the
diet and the actual average daily dietary intake of radtoactivity for

radioactivity levels in water, air, soil, plants, and animals are
. changing with time.
(Included should be measurements of radionuclide
content of air and collection of information on the chemical and physicd
form and size distribution of particles in the air containing 23954.)

Information from such surveys will provide a continuing check of
the radiological status of the people and theenvizonment and will
assure that the exposure criteria is not being approached or exceeded,
13. Considering that the method of disposal of plutonium contaminated soil
and scrap has not yet been decided, that not enough information is
available to determine whether it is feasible to remove plutonium from
the soil to reducethe amount of material requiring disposal, and not
wanting such problems to delay cleanup and rehabililation of the
Atoll, the Task Group recommends the following:
