The Atomic Energy Act of 1946 was a significant piece of legislation in the United States that established a framework for the control and regulation of atomic energy. It aimed to promote the peaceful use of atomic energy while ensuring that nuclear materials were not used for military purposes. The act created the Atomic Energy Commission (AEC) to oversee the development and regulation of nuclear energy and technology. This legislation marked the beginning of the U.S. government's efforts to manage the complexities of atomic energy following the end of World War II. It set the stage for future policies regarding nuclear power, research, and safety, reflecting the dual goals of harnessing atomic energy for civilian use while preventing its proliferation for military applications.
