Citizen Science and the Politics of Environmental Data.

In this commentary, I reflect on the differences between two independent citizen approaches to monitoring radiological contamination, one in Belarus after the 1986 Chernobyl nuclear accident and the other in Japan following the 2011 Fukushima Daiichi accident. I examine these approaches from the perspective of their contribution to making radiological contamination more publicly visible (i.e., publicly recognized as a hazard). The analysis is grounded in my earlier work (Kuchinskaya 2014), where I examined how we have come to know what we know about post–Chernobyl contamination and its effects in Belarus, a former Soviet republic most heavily affected by the fallout. As I described in this study, much of what we know about the consequences of Chernobyl is based on the work of the Belarusian nonprofit Institute of Radiation Safety, "Belrad." I compare Belrad's approach to radiological monitoring with the work of the volunteer network Safecast, arguably one of the best-known citizen science projects in the world, which is working to monitor the scope of the post–Fukushima contamination. Through this comparison of approaches, I raise broader questions about a form of sensing practices—data-related practices of citizen science that make environmental hazards publicly in/visible.
