In Radiant Infrastructures Rahul Mukherjee explores how the media coverage of nuclear power plants and cellular phone antennas in India—what he calls radiant infrastructures—creates environmental publics: groups of activists, scientists, and policy makers who use media to influence public opinion. In documentaries, lifestyle television shows, newspapers, Bollywood films, and through other forms of media (including radiation sensing technologies), these publics articulate contesting views about the relationships between modernity, wireless signals, and nuclear power. From testimonies of cancer patients who live close to cell towers to power plant operators working to contain information about radiation leaks and health risks, discussions in the media show radiant infrastructures are at once harbingers of optimism about India's development and emitters of potentially carcinogenic radiation. In tracing these dynamics, Mukherjee expands understandings of the relationship between media and infrastructure and how people make sense of their everyday encounters with technology and the environment.
