On 18 Sept. 61, Gerry Johnson sent a draft paper entitled, "Nuclear Test Program," to the Deputy Sec. of Defense. The paper has been coordinated with DDR&E and DASA and apparently is the same as a draft to be presented to the AEC for approval immediately. } 5 If approved, apparently the paper would go to the National Security Council who requested such a study by NSA memo No. 87. eptember ; 18 Sep ? , are, W nd welf n and U.S. Secretary of Health, Educatio out over . fall in rise Abraham Ribicoff, reports sharp it oes n° says but eastern and northern parts of U.S. o levels n atio radi : n : pose public health danger "unless . time of iod per long a over ned tai sus are ge this ran wr There is a great deal more discussion in these files but now I start getting into an area where we have plenty of documentation in other files, from other sources, so! will just mention a few things. An 18 September, Memo in the NVOO files documents the facts that LASL Py| is interested in further geological surveys at the Test Site, not as ta what they might have to do with suchas the Christmas Tree concept, but for yA . very decp hole sampling down to 6000 fect in Arca 3 and also deep He 4f holes in other areas suchas Area 15. The purpose of these discussions and requests for surveying is to locate areas that might be feasible sites for higher yield tests and just to learn more about the geology as well as to avoid the sround water problem in certain areas.
