Release of a report on the joint project with the IAEA regarding Marine Monitoring

June 27, 2022

After the accident of Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Station, Japan has been cooperating with the International Atomic Energy Agency (IAEA) in Marine Monitoring: Confidence Building and Data Quality Assurance since 2014 to ensure the reliability and transparency of Sea Area Monitoring data.

  1. The IAEA and Japan organized a joint sampling to collect sea water, sediment and fish samples and compared analysis results of radionuclide between laboratories, as Interlaboratory Comparisons (ILCs)1 in 2021.
    Third-country laboratories from France, Germany and the Republic of Korea also participatd in ILC 2021.
  2. On 27 June, the IAEA released a report on the results of the ILCs stating that Japan's sample collection procedures were appropriate and a high level of accuracy and competence on the part of Japanese laboratories involved in the analyses of radionuclide as part of the Sea Area Monitoring was demonstrated.
  3. IAEA Marine Monitoring will be continued in the future.

ILC is a test to check if laboratories’ analytical methods for radioactive material are appropriate, by comfirming analytical methods and comparing analysis results between laboratories, using the identical samples during all the process from sampling to analysis.
