[en] The exhibition has been induced by the observation that psychologists and social scientists remained relatively mute in the public discussion about the peaceful uses of nuclear energy and the hazards involved for mankind. Did they really, or did the public just not listen to them. This question initiated the search for publications by experts in the two fields, and the present exhibition and relevant bibliographic material point to statements and other publications by well-known authors, showing the psychological and social aspects of the problem. The material covers citations, references, and supplementing texts from political or medical publications, and it becomes clear that there have been mechanisms of suppression that put aside many an important aspect. A bibliography of literature by social scientists is given. (HSCH)
