“The Utopian Promise of the Peacetime Atom”"The Atomic Energy Act of 1946, known informally as the McMahon Act, established the Atomic Energy Commission (AEC) as a federal institution to have total control of developments in the field of atomic energy. To replace the predominate image of atomic weapons as destructive, the AEC began a public relations campaign to show the atom’s positive side. Hopes for a utopian society with atomic-powered cars and airplanes had died down by the late 1940s. But the promise of atomic energy for medical research, diagnosis, and treatment and for preventing starvation through duplicating photosynthesis remained. In 1954, President Dwight D. Eisenhower signed a revision to the McMahon Act opening development to private industry. In the following article from the popular magazine Look published a year later, David O. Woodbury reprised the “utopian promise” rhetoric of the late 1940s, as he discussed the potential of radioisotopes for health, food production, and industry, as well as the production of electric power through atomic energy. The first nuclear power plant began operation in 1957 and facilities proliferated during the next two decades. Due to a drop in demand for electricity, a strong grassroots antinuclear movement concerned about safety and the disposal of nuclear waste, and national anxiety after the Three Mile Island accident in 1979, no new facilities were built after 1979 and many have been shut down.
