There is apparently no scientific foubt that the world-wide radiation generated in an all-out war of H-bemhs would be a hazard to life over the whole globe. Scientists also seem to be agreed that the testing of H-bombs involves at least a certain risk. The issue is over the immediacy of the radiation danger--that is, just how many tests the different nations may conduct before the cancer threshold is crossed. This must be measured against the contribution tests make to our military security. without now judging this question, however, we feel that the potential danger alone justifies a much greater effort to explore the vossibilities for the treatment or, hopefully, prevention of raciation-incuced cancer, 2. leukemia, and cell cegeneration. Vigorous Reassertion of Your Supoort of an International Atomics aneray agency. ve believe that the vast majority of the american people are fully behind your dramatic effort to develop peaceful uses of the atom through the United Nations. As Congressmen, we are anxious for the momentum behind these proposals to be sustained. The exercise of your prestige and leadership will not only ensure the passage of the appropriate legislation. It will also present the proper image of the United States as a nation devoted to using the atom to builc a better world. z=}ie _ 3. a o- A National Shelter Program. “” ew " -“ The policy of mass evacuation, on which the Unitea States planned to rely in a war of atom bombs, is now cutmoded by the vastly more powerful H-bombs. A fifty megaton H=bomb can incinerate all life within a radius of 15 miles of the explosion. ithin a few cays the people who live in the downwind area of fallcut will also sicken and die. Uncer these circumstances, it appears prudent and imperative to provide some form of shelter for our people at the places where they live and work. Gur capacity to take a blow and keep on fighting is just as important as our ability to deliver one. «an adequate system of shelters will therefore give pause to a potential aggressor and make a formidable contribution to our policy of deterrence.
