weapons which will lead to more efficient use af both tactical and strategic atomic weapons should the need arise, In short, enormous gaing in defensive power of the free world have come from these tests. The detonations have produced no substantial hazards to the public health and safety. n the proving ground itself mone af the worlmen, the scientists, engineers nor the troopa have com even close te experiencing radiation sickness or blast injury. For the people off-site there has been no reason to give serious sonsideration to injury. The record of highest radiation exposures in populated areas cutside the proving ground has been published in the AEC's 14th Semianmial Report to Congress. It's analysis shows no hazard to health. Livestock grazing in the immediate vicinity ef the proving ground have suffered some nominal injury from radioactive fall-out. (Hare supply the facts ef:are finally determined.) The Livestock herds and flocks affected were in close-in areas where their grasing was a calculated risk on the part of the owers. Nevertheless the AEC has moved to compensate.(Here what the facts turn out to be.) The tests have brought inconvenience to some industries and scientific study enterprises whose products or operations are affected by increase in the background radiation brought on by radioactive fall-out. The film industry, hovevar. with AEC cooperation has learned to live with the RRC ae
