Operational Phase of IVY.
Reference (a) sets forth preliminary planning of CJTF 7 regarding
rediological safety measures pro, ,osed for Operation CASTLE in relation
to these iaplemented for Operation IVY, and requests CINCPACFLT comnants
or suggestions in order that task force planning aay be realistic and
oatually agreeable to all concerned.
For convenient refercace, the task
force plan is summarised in paragraph 2 bulow.
a.
No special efforts will be implemented by JTF 7 in support of
the following safety ceasures:
(1)
Atemis cloud tracking outside the immediate danger area.
(2} Sampling of drinking water on distant atolls.
(3) Svacuation of native populations.
b.
The conslusion to discontinue the above safetymeasures ( estab=
lished for Operation IVY) is based on the following factors:
(1) Olecussions between cognisant sections of both headquarters
during February 1953.
(2) Reliance on the substantial radiological documentation ob=
tained for IVY in reference (b).
(3)
Apparent unrealism in the assumption of health hazards of &
magiuitude conjectured for IVY.
