I’m pleased to announce a special issue of the Journal of the History of Biology (vol. 54, issue 1), which I have guest-edited with my colleague Linda M. Richards. It focuses on the history of radiation exposure, and it draws together stories of science, activism, art, culture, and struggles over historical narrative. It includes essays by scholars who participated in workshops related to the OSU Downwinders Project, as part of a research effort funded by the National Science Foundation. Contributing authors to the special issue include M. X. Mitchell, Cynthia Folkers, Jonathan Luedee, N. A. J. Taylor, Sumiko Hatakeyama, and David K. Hecht.
