Cooperation with Fukushima Prefecture in the area of radiation monitoring and remediation

Following the accident at TEPCO’s Fukushima Daiichi nuclear power plant, the IAEA and the Fukushima Prefecture agreed to cooperate on radiation monitoring and remediation. The Practical Arrangements on this cooperation aim to provide broad and extensive assistance in the Prefecture in these two areas, complementing existing Japanese activities and providing immediate assistance and support that directly benefit those living in the Prefecture.

The cooperation covers assistance in research and study on:

  • Radiation monitoring, including the application of environmental mapping technology by using unmanned aerial vehicles, and using radiation monitoring data to develop maps to be made available to the public;
  • Off-site decontamination, including in analyses of environmental monitoring results and the exploration of exposure pathways so as to reduce or avoid exposure; and
  • The management of radioactive waste and on management methods of low-level radioactive waste from off-site decontamination activities.

A project on the application of environmental mapping technology and the use of radiation monitoring data to develop maps for the public has been successfully concluded.

Reports on the cooperative activities are prepared by the IAEA and the Prefecture respectively, describing the progress of projects dealing with the movement of radioactivity in forests and wild animals; decontamination strategies for rivers and lakes; and management methods of low-level radioactive waste produced during decontamination activities.

Four mid-term reports were released in April 2021, which document the developments in the implementation of the Practical Arrangements between 2013 and 2020. Two were prepared by the IAEA and two by Fukushima Prefecture. The reports are available below in both English and Japanese.

IAEA mid-term summary reports

These reports are written by the IAEA and document the radiation monitoring and remediation activities identified and proposed by the IAEA under the Fukushima Cooperation Projects agreed in 2012.

Activities are conducted by Fukushima Prefecture and include monitoring of air dose rates of radiocaesium, protection of forest workers against radiation, safe management of radioactive waste from remediation activities and effective communication of these results to the general population.

Fukushima Prefecture interim reports

These reports are written by the Fukushima Prefectural government and document the Fukushima Prefecture Initiative Projects in radiation monitoring and remediation that supplement activities under the Fukushima Cooperation Project.

Projects are supported by the IAEA and include monitoring of the movement of radionuclides in river waters and among wildlife such as wild boar, in order to foster a sense of safety and security and in light of lifting shipping restrictions, and the development of environmental mapping using Global Positioning System (GPS) data for quick and precise radioactivity measurements, particularly across terrain that is inaccessible on foot.

Other materials

The IAEA assists Fukushima Prefecture on the dissemination of information on the areas of work under the cooperation on radiation monitoring and remediation. This includes the preparation and publication of information materials for its citizens on radiation such as:

  • A series of brochures on the outcomes of the cooperation (JP/EN)
  • The Fukushima Prefecture Newsletter on Environmental Radiation Monitoring- Fukumoni (JP/EN)
  • The Information and Advice for Hunters brochure (EN).

Reports and other materials are also available on the Fukushima Prefectural Centre for Environmental Creation website in English and Japanese, along with research results, survey reports and technical information.

They can also be found in Japanese only, here.
