The nuclear accident at Three Mile Island in March 1979 was as much a social-systems failure as it was an engineering failure. It raised questions not only about the regulation and management of nuclear-power plants but also about the effects of nuclear accidents on the community, on society, and on the total controversy surrounding nuclear energy. Questions were also raised about public perceptions of the risks of high technology. At the request of the President's Commission on the Accident at Three Mile Island (the Kemeny Commission), the Social Science Research Council commissioned social scientists to write a series of papers on the human dimensions of the event. This volume includes those papers, in revised and expanded form, and a comprehensive bibliography of published and unpublished social science research on the accident and its aftermath.
