An interview between Joi Iti, Sean Bonner and Pieter Franken, the co-founders of Safecast, a citizen science organisation that formed in response to Fukushima nuclear disaster. At the time of the disaster, information on local radiation level was scarce, but their organisation combined a crowd-sourcing approach with cutting edge and easily sourced technology to quickly begin monitoring, collecting, and openly sharing information on environmental radiation.
