Fukushima and Radiological Contaminated Environments World-wide: The Important Role of Environmental Chemistry and Radiochemistry in Remediation and Restoration (#374)

The Fukushima Daiichi nuclear power station accident in March 2011 released substantial amounts of radionuclides, such as Cs-134, Cs-137, Sr-90, I-129 and transuranium nuclides, to land, rivers, and the seacoast in the Fukushima and neighboring prefectures. Numerous cleanup activities have been undertaken since then. However, the environmental restoration of the contaminated areas is very difficult, costly, and far from being finished. More advanced remediation techniques must be developed to replace or complement the current methods to accelerate the decontamination efforts. This symposium will provide an opportunity to review and discuss the current technological approaches from the standpoint of environmental chemistry and radiochemistry. Furthermore, technical and scientific issues of decontamination techniques and migration behavior of relevant radionuclides will be discussed. Similar experiences, findings and knowledge of the restoration of nuclear legacy in United States and Europe will be also shared, as they may be helpful for the ongoing and planned decontamination efforts in Japan. The symposium will cover 1) a scientific and technical review of the current decontamination programs in Japan, 2) recommendations from research-based decontamination experiences in other countries, and 3) our role as chemists to effectively contribute to the environmental remediation in Fukushima.
