A half-day Workshop on Medical Applications of Radiation and Metrology Standards Workshop was held at Minamisoma city, Fukushima prefecture, Japan, 16 September 2025. It was organized by the Fukushima Institute for Research Education and Innovation (F-REI) with the support of National Metrology Institute of Japan (NMIJ) and the CCRI section I “dosimetry” and was followed by 116 participants, 48 of them connected remotely.

Japan has a long history of ionizing radiation therapy, and as expected for a technologically advanced nation, boasts a very impressive range of radiotherapy facilities. Japan is a recognized world leader in innovative treatment modalities, including carbon-ion therapy, theranostics (use of radionuclides for diagnosis and treatment of cancer) and boron neutron capture therapy (BNCT). The Fukushima district is also in an era of major revitalization, with the Fukushima Institute for Research Education and Innovation having an ambitious plan to become a major research and development institute, centered around 5 technology pillars, which all directly or indirectly implicate ionizing radiation measurement science. The workshop opened with a detailed overview of F-REI and its combined technological and societal aims. This was followed by presentations on developments in radiological medicine and the status of radiotherapy in Japan. In the second part of the workshop, the focus narrowed to ionizing radiation (IR) metrology with contributions from CCRI members and from the Japanese National Metrological Institute (NMIJ) and long-time partner of the international IR community.

During the discussions that followed, it was noted that information sharing, as through this workshop, between entities such as F-REI, NMIJ and CCRI is of mutual benefit and necessary to explore future collaborations and develop common messaging on the benefits of ionizing radiation in addressing global health needs. Best practice in engaging with local communities, high schools and universities on the challenges and opportunities of radiation science was also shared.

CCRI also deeply expressed its gratitude to F-REI and NMIJ for their exceptional support and welcome in all the events organized at Minamisoma that week.
