September 19, 1952. Dear Mr. Durham: On September 16 I advised you by telephone that the executive agencies are making no public statements nor giving background information to uncleared correspondents or others on the autumn test series at Eniwetok, This policy I explained is to prevail until after the conciusion of the tests and the public reporting at that time is to be less extensive than on previous tests. . This policy was arrived at for the executive agencies following a Psychological Strategy Board study whose recommendations were endorsed by the National Security Council. I am sending a copy of the PSB study which sets forth the reasons for the policy, and of the NSC directive to the executive agencies | clearly setting out the limited public reporting to be done on the test series. This policy cannot be fully effective unless it is followed: by the Joint Committee members and. staffas well as by the executive branch agencies. We trust that you and the otner. members of the Committee will agree that it is in the national interest. So that the members not in Washington may know of it, we Will appreciate your conveying its general terms to them and forwarding the Commission's request that they pursue the same course. JI regret that the NSC instruction to the executive _ agencies was not available earlier, and hasten to send it on now that it has become available. sincerely yours, H,. D.
