(2) Sampling of drinking water at distant atalls will be con- ducted ag a post~ehot effort only in the event of radiological conditions requiring such action. (3) Bwacuation of native populations is not planned for JTF 7 effort due to unavailability of task force equipment. However, consider= ation of populated islands will be one of the aijor factors influencing the decision te shoot. 3. Sinee IVY provides the sale criterion for the present determination of adequate safety precautions fer the Pacifis area incident to thermo~ nuslear teste, it is considered appropriate to review the measures im Plomented for that eperation. For this purpose, the basic directives, advisories and precautions pertinent -to IVE safety are briefly outlined is peregrephs 4 through 6 below. be forIVY. &. Referance (e). In consonance with the JCS decision relative to responsibilities during future tests at the Pacific Proving Cround, CINCP. directed CJTF 132 to: (1) Advise CINCPAC at an appropriate time of special hazards in- volved in the tests and appropriate precautions required to insure safety ac -4.
