Every year, we at the Radiation Effects Research Foundation (RERF) hold an Open House event to introduce our research activities to the general public.

In addition to exhibits and panel explanations, we have planned hands-on activities. We warmly welcome not only those interested in research, but also students and children interested in science and radiation, and families with young children. Please invite your friends and family members and be sure to stop by.
Since the RERF Hiroshima Laboratory will be relocating to Hiroshima University Kasumi campus next year, this will be the last event held at our current location in Hijiyama.

The dates and times for both venues are listed below. Refer to the relevant information on the flyer below for the details of the exhibits.

Please be aware that the event may be canceled due to unavoidable circumstances such as inclement weather or emergencies. In such cases, we will post an announcement on this website.
