concentrations subsequent to those cleanup efforts directed toward scrap
removal and soil removal from areas of highest transuranic soil
concentrations begun in 1977,
The purpose of this report, as a result of now having more data
available, is to refine the dose predictions for alternate living
patterns proposed for the resettlement of Enewetak Atoll.
For many reasons:the time frame for developing the assessment of
the alternate living patterns based on all of these new data were quite
short.
Initial requests for the assessment by May 1979 were impossibdle
to meet because time to collect and analyze the samples and evaluate the
data exceeded the time allotted.
Extension to July 1979, made a new
assessment possible but required some compromises to meet the deadline.
For example,

Samples from these projects
which involved planting and harvesting the subsistence food crops, have
only become available in the past year and a half,
and the data base for
each subsistence crop is not és complete as it will be within the next
year or two.
Studies of the marine environment and ground water have
been continuing since 1974,
The program to determine the concentration of \37e— and 205,
in the soil and the external gamma exposure was begun in February 1979,
at the conclusion of the cleanup activities at the atoll.

Starting in
soil samples were collected in a 50-m grid on all of the
northern islands at Enewetak Atoll.
However because of time and budget
restrictions, only samples on a 100-m grid were analyzed for 20s; and
