MEMORANDUM Morse Salisbury, Director, Division of Information SUBJECT: Services, @. S. Atomic Energy Commission PUBLIC REPORTING POLICY FOR IVY At the recommendation of a panel comprised of representatives of the Departments of State and Defense, the Central Intelligence Agency, the Atomic Energy Commission, and the Psychological Strategy Board, the PSB has endorsed a public reporting policy for IVY. This policy provides that no further public statements shall be issued, nor background information be given to correspondents or other uncleared persons concerning the tests until the conclusion of the series, unless unforeseen circumstances make issuance necessary. So far as can now be foreseen, the only contingency likely to make necessary a public statement before the end of the series, would be some occurrence of detectable phenomena or other special circumstance in connection with the Mike shot. The Department of Defense, through its membership on the PSB has coneurred in this policy. The Commission has accepted it, Operating officers will of course be expected to conform to it. In due time the formal documents will be forthcoming from the PSB through the top offices of the DOD and the AEC. In the meantime I am sending this notice of the policy that has been adopted so that we may know of it and not inadvertently deviate from it. Compliance is simple: No public statements in connection with IV¥Y from now on until the conclusion of the tests, unless unusual events or circumstances make public statements necessary. In case Such events or circumstances should arise, the public statements proposed should be cleared through AEC, DOD, and possibly State. The Public Information Service, AEC, will act as clearance agent. if such events arise. Addressees: , .
