Tweets from Fukushima: Connected Sensors and Social Media for Dissemination after a Nuclear Accident

Digital services for information and communication, especially social media, are increasingly being used to share the information required to manage disasters such as a nuclear accident. In this particular case, victims can only rely on measurements to evaluate the radioactive contamination of the environment, food and people. This chapter presents a study that is the accident that took place at the Japanese Fukushima Daiichi Nuclear Power Plant in March 2011. It also deals with a type of connected object, the radiameter, which is a physical object endowed with radioactivity sensors. Social media is an important lever for the diffusion of information, especially during natural or industrial disasters. The chapter details the spread of measurements from connected sensors via social media during the post‐accident phase of the Fukushima Daiichi nuclear accident. It further discusses the forms and processes of the dissemination of information relating to radiation measurements via Twitter.
