erties The GAC wishes to reaffirm the views previously expressed with respect to the importance ‘of tests of nuclear weapon design as a necessary means of progress. The GAC further strongly endorses the recommendations in the staff papers with respect to the NPG. ~ However, the GAG does not believe that the number of tests should be limited to 10 per year as suggested, but that the number should be determined by the needs of the weapon laboratories and the Division of Military Application. The GAC fully endorses the recommendation that each proposal for a test should be scrutinized with the utmost care as to need, and that no effort should be spared to exercise the greatest pre~ | eautions to safeguard the surrounding communities and the test personnel with respect to fall-out, blast, and blast damage. With the increased understanding of these proposals, precautionary measures become more effective. _ The GAC knows of no substitute for tests on the continental. site to maintain our lead in the field of atomic weapons. We have seen no suggestion for another site which. has the advantages of the NPG, , , : The GAC therefore recommends that the use of the NPG be continued, and that no arbitrary limitation should be imposed on the number of ‘tests in any given period. At the same time the GAC recognizes that unless the greatest precautions are taken, a certain element of danger will always attend tests of nuclear weapons, Sincerely yours, I, I. Rabi Chairman
