The purpose of this study was to examine what kind of changes could be seen in risk perception and opinion by presenting information on geological disposal of high-level radioactive waste. In particular, we focused on the effect of presenting ambiguous information that discussions with experts continue. In this presentation, we will report the results of a questionnaire experiment using the Internet in December 2019(N=1,000). Also, we report on the analysis for individual characteristics such as how to perceive as ambiguous, and a threat to freedom of information presented.
