THE CASE FOR CLEAN NUCLEAR WEAPONS | All nuciear weapons of present design produce large amounts pf radicactive debris « in the alr when alr burst, on the ground and in the aly when ground burst. Human injury fram this debris is directly proportional te the amount produced and absorbed. Scientists disagree on the hasards imposed by nuciear tests. (They agree that the debris and its human effects from nuclear war with present weapons would be infinitely worse than tests. They disagree som t upon the ultimate world-wide injury from wartime nuclear debris, as they do on the similar but jesser issue of teste. The moat pessimi believe that the human race may be deformed or annihilated. Others are more sanguine. Even the most sanguine anticipate many casualties from wartime radioactive debris in or near areas of conflict. No one knaws; and the growing problem of world-wide contamination, even from pepcetal uses and radioactive waste disposal, is a subject af increasing concern. At this initlal stage of knowledge, it would be foolhardy to create vast quantities of radioactive debris by nuclear war, despite the belief of some scientists that its effects would be insignificant in comparigon with the direct effects of such a war. As insurance for us and for hurnanity against the possibility that the optimiets might be wrong, rr would be wise to avoid this incompletely evaluated peril as best we can - by avoiding nuclear war, if possible, and by using only clean weapons if we cannot avoid it. We depend increasingly upon nuclear weapons to oppose Russia; yet our clean weapon capabilitics are still embryonic. The stockpil contains none. Without policy changes and continued tests there w never be many because the military show little real interest in cl weapons, and wholly clean ones cannot be developed if tests stop. the other hand, given a high priority, continued tests should bring advances in this field similar to the phenomenal progress achieved in high yield weapons. There are compelling reasons why all nuclear weapons should| be basically clean. Some of the reasons for development of clean weapons of all sizes are - DECLASSIFIED Authority AiR 76-45, #13) By AK/18NLE DATE ._Sltelgc SESGRET wena 8 ! !
