The disaster at the Chernobyl nuclear power plant was an event of obviously transnational significance—not only in the airborne particulates it deposited across the Northern hemisphere, but in the political and social repercussions it set off well beyond the Soviet bloc. Focusing on the cases of Great Britain and France, this innovative study explores the discourses and narratives that arose in the wake of the incident among both state and nonstate actors. It gives a thorough account of the stereotypes, framings, and “othering” strategies that shaped Western European nations’ responses to the disaster, and of their efforts to come to terms with its long-term consequences up to the present day.
