For day 1, it was held jointly with the 2022 ERAN Annual Meeting, and the Oral and poster presentation were conducted. All the oral presentations for experts were given in English. We received many questions from participants, such as how groundwater is affected by tritium. The “Student Award” was presented to students who gave the outstanding poster presentation at this year’s poster session. Three students received the award, including KUROSAWA Honoka, a PhD student in the IER and Polina PAVLENKO, who has been accepted in the SATREPS Chernobyl project.

For day 2, in the symposium for the general public, six IER professors gave presentations on the theme “Environmental Radioactivity: New Frontiers”. We received a variety of questions from participants, both from researchers and the general public. Several questions were asked about ALPS treated water, indicating the high interest in the release of ALPS treated water from the Fukushima Dai-ichi Nuclear Power Plant. In the discussion session, all presenters were asked about their thoughts: what kind of thoughts led to their presentation.

Thank you very much for your participation in the annual symposium!
