The regulation of atomic energy has had a long and unique history in the United States and it is the effectiveness of that regulation which poses the problem analyzed here. Government documents and secondary sources are used to provide data and critical opinion about atomic energy regulation. The first chapter deals with the history of the earliest attempts to deal vith atomic energy while the second chapter is concerned with the political nature of the Atomic Energy Commission (AEC). Questions o secrecy and potential environmental danger from the nuclear enterprise are topics for the third and fourth chapters respectively. A concluding chapter indicates the future direction the regulation of nuclear power may take under the newly established Nuclear Regulatory Commission and the Energy Research and Development Administration.
