AEA Restricted Data
All of the surveys were completed well within the limit of exposure
established for the mission.
The results were very effective in com
pleting studies of the radiation intensities on the islands.
Restriction ofIslands.
Early in the operations, it was decided at a conference that as a
result of radiological studies of CTG-7.6 would recommend which islands
would be restricted to all personnel because of radiological intensities
and which would be opened for further work and for recreation.
Accord-
ingly, as soon as possible following each test, extensive surveys were
made of all islands in the atoll to determine the extent of radioactive
fallout.
The recommendations made as a result of this study were
accepted, and provided CJTF=7 with the desiréd information as to safety
in the lagoon,
it permitted the planning of. scientific missions which
required working on the islands and the designation of beach and
recreational facilities safe for use.
The original sequence of and
locations for the atomic tests were selected in advance so that the
prevailing weather conditions would confine radioactivity to a progressively expanding area and at the end of the tests the islands of
Parry and Eniwetok, on which the garrisons were stationed, would remain
free of fallout and consequently be radiologically safe for occupation.
