Of the 4 IAEA laboratories concerned, three are environmental laboratories: the Isotope Hydrology Laboratory in Vienna; Terrestrial Environmental Radiochemistry Laboratory in Seebersdorf, 35 kilometers south of Vienna; and the Radiometrics Laboratory in Monaco. The second laboratory is the Radiation Security Technical Companies Laboratory in Vienna.

From 29 August to 2 September, the duty drive met in Vienna and traveled to Sibersdorf and Monaco to go to all 4 laboratories. They mentioned analytical methods for estimating the radionuclide content material of samples, the timeline for the work, and future evaluation for extra samples.

IAEA consultants briefed the duty drive on the right way to put together to research greater than 30 totally different radioisotopes in every water pattern with the assist of superior instrumentation. Specialists clarify the variations in how every radioisotope is measured and the way the samples are ready. Joint improvement work in laboratories with particular person analytes will guarantee the absolute best outcomes even for the in any other case difficult evaluation of irregular radionuclides. “The IAEA laboratories are working collectively to make sure a complete scientific evaluation and make sure the info from TEPCO. We’re working exhausting to make sure that these preliminary outcomes attain the worldwide neighborhood earlier than the beginning of water discharge in 2023. will be supplied,” Caruso mentioned.

The Job Pressure additionally mentioned strategies and preparedness for verifying the industrial radiation safety capabilities of TEPCO and Fukushima Daiichi Nuclear Energy Station. The proposed technical overview and analysis are based mostly on the necessities for the evaluation of occupational danger as specified within the Normal Security Information No. GSG-7.

Earlier this 12 months, the IAEA facilitated two sampling campaigns of handled water from Fukushima Daiichi for evaluation by the company and third-party laboratories. Further sampling expeditions from Fukushima Daiichi and the encircling marine surroundings are deliberate within the coming months and years. The IAEA conducts routine efficiency checks annually for about 500 laboratories measuring radionuclides within the surroundings, which serves as a scientific baseline to evaluate the standard and capabilities of collaborating laboratories.
