What Preparations Are Required of Authorities for Consensus Building on the Recycling of Low-Level Radioactive Soil: Insights from Advancing and Stalled Cases

The present study aimed to identify key points that authorities should consider in dialogues with local stakeholders regarding the recycling of soil containing low-level radioactive materials. We conducted a quantitative analysis of publicly available information from resident briefing sessions in two stalled cases, and a qualitative analysis of an interview with a local government official in one advancing case, regarding soil recycling in Japan following the Fukushima Daiichi nuclear power station accident. In the stalled cases, residents prioritised not only radiation safety but also feelings of assuredness and the rationale for selecting the site. In the advancing case, the project was organised from the bottom up, and its progress was attributed to a local government official supporting horizontal collaboration between the national government and residents. Based on these results, the following are recommended for authorities: Emphasise local government officials as mediators for horizontal collaboration between the national government and residents; aim not only to ensure an understanding of safety but also to foster feelings of assuredness; and disclose all information, including the rationale for choosing the region and the anticipated impacts of the project on the community.
