Titre : Thinking about the co-production of knowledge outside “hybrid forums”: the controversy surrounding mine waste inventory. The case of the former uranium mine in Pen Ar Ran (Piriac-sur-Mer, Loire-Atlantique) Auteurs : Saliha Hadna, Revue : Technology and Innovation Numéro : Issue 4 Volume : 3 Date : 2018/09/7 DOI : 10.21494/ISTE.OP.2018.0287 ISSN : 2399-8571 Résumé : In this article, we take an interest in a former uranium mine’s environmental monitoring. The particular case of the Pen Ar Ran mine (Loire-Atlantique) shows that even if any instance for dialogue with populations has been created, a group of organized citizens has contributed to the decontamination of some areas which have been impacted by radioactivity. We analyze the course pursued by this cause and the method used by citizens in knowledge production on radioactivity. Éditeur : ISTE OpenScience
