Release of reports and a video on the joint project with the IAEA regarding Marine Monitoring: Confidence Building and Data Quality Assurance

August 2, 2021

After the accident of Tokyo Electric Power Company’s Fukushima Daiichi 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.

The IAEA and Japan organized annual joint sampling to collect sea water, sediment and fish samples collected and compared analysis results of radionuclide between laboratories, as Interlaboratory Comparisons (ILCs) (Note) from 2017 to 2020.

On 30 July, the IAEA have 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.

In addition, the IAEA released a video introducing ILCs in Marine Monitoring Review.

IAEA Marine Monitoring will be continued and its details are under the discussion between the GOJ and the IAEA.

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