AUG 11 1972
During the period Julv 26, 1972, to August 2, 1972, a joint AEC-DOD team
visited Eniwetok Atoii to conduct a survey of those portions of Runit
Island which are to be used for a PACE cratering experiment.
A thorough
radiolosicel survey was made of that portion of the island which will be
disturbed by this experinent.
Soil samples were taken in the exnected
crater area.
Jn addition, a survey for plutonium particles was made
along the access road and 22 locations were identified as potential
sites for plutonium debris.
We
lsaon
he results of this survey will be used io
determine the precautions required for conducting the PACH experiment as
planned, or the necessity for relocating the experiment scheduled for
Runit Island.
Along the ovean recf of Runit there is a very large quantity of scrap
metal debris covered with water to various depths depending cn the tide.
This debris resulted from the tests on Runit.
Some of it was blown
onto the reef by these tests.
Some was pushed onto the reef during
cleanup orerations in preparation for ether tests.
Much of the debris
is metal scrap romainine from the complex diagnostic experiments conducted
during the LACROSSE event, which was a surface burst.
A spot check of
one pile indicated that the debris is contaminated to levels that would
require removal in a subsequent cleanup operation.
Experience with
similar scrap at Bitini suggests that materials blown onto the reef will
also be contaminated.
It is expected that the quarantine on Runit will remain in effect urtil
AEC and DOD have reached agreement on the plans and precautions that are
needed.
The PACK staff is drafting a report, for AEC consideration, of
the survey and remedial actions necessary to continue the PACE experiment
on Runit.
