The National Institute of Metrology (Thailand) (NIMT) congratulates the Office of Atoms for Peace (OAP), Thailand’s Designated Institute in ionizing radiation, on its official acceptance as a member of Section I “Dosimetry” of the Consultative Committee for Ionizing Radiation (CCRI).
The 2025 meeting of CCRI Section I “Dosimetry” was held in Minamisoma City, Fukushima Prefecture, Japan, during 17–18 September 2025. The meeting was hosted with the support of the Fukushima Institute for Research Education and Innovation (F-REI) and the National Metrology Institute of Japan (NMIJ). Approximately 50 participants, including 10 online attendees, convened to review the current status of dosimetry worldwide and to discuss future technical developments in ionizing radiation metrology.
During the meeting, the Committee officially welcomed two new members: OAP (Thailand) and FANR (United Arab Emirates). The inclusion of OAP as a member of CCRI Section I reflects Thailand’s strengthened technical capabilities and international recognition in the field of radiation dosimetry. OAP’s presentation to the Committee further demonstrated the country’s commitment to advancing measurement standards in ionizing radiation and contributing actively to the global metrology community.
As Thailand’s National Metrology Institute, NIMT expresses its sincere congratulations to OAP on this important milestone. OAP’s membership in CCRI Section I enhances Thailand’s visibility and role in the international metrology system, reinforces national measurement infrastructure, and supports the country’s continued development in radiation protection, medical dosimetry, and nuclear applications.
This achievement marks another significant step in strengthening Thailand’s position within the international metrology framework and promoting excellence in ionizing radiation measurements for the benefit of society and industry.
