ua In the Foreword to the Summary Report, Dr, Bronk stated: The use of atomic energy is perhaps one of the few major technological developments of the past 50 years in which careful consideration of the relationship of a new technology to the needs and welfare of human beings has kept pace with its development. Almost from the very beginning of the day of the Manhattan Project careful attention has been given to the biological and medical aspects of the subject, By contrast, the automobile revolutionized our pattern of living and working, but we are only now beginning to appreciate the problems of safety, urban congestion, nervous tension and atmospheric pollution which have accompanied its development. In the same way, the development of the aircraft industry outran our knowledge of how to meet the environmental needs of the human beings it intended to transport through the skies," The scientists, save for the geneticists, were all persons who had actively participated in the past in the efforts to reduce industrial toxicological hazards, air pollution, stream and harbor pollution, and soll and crop pollution, and destruction which has occurred with developing industries largely uncontrolled until serilous damage had already taken place, They are determined that with 4 much greater body of knowledge to draw on concerning radiation effects, similar situations will not arise as a result of the rapidly growing atomic energy industry with its even greater potential dangers, Consequently, once they had assured themselves on two points, namely; weapons testing at the present rate and with present safeguards was not a present menace, and the safety precautions of our present atomic energy operations were indeed effective, they became preoccupled with pointing out the problems (=< 5} * Enclosure II
