- Institute of Environmental Radioactivity Radioecology Division, Soil and Plant Dynamics
Ph.D. in Agricultural Science. My area of expertise is Environmental Radioecology. My research focuses on the behavior and transfer of radionuclides in the terrestrial environment utilizing their speciation.
Main Focus of Research
- Elucidation of radionuclide transfer from soil to crop
- Elucidation of dynamics of radiocaesium in reservoirs
- Evaluation of radiocaesium and 90Sr activity concentrations in agricultural crops collected from Fukushima Prefecture and radiation dose estimation from foods
Fields of Research
Environmental Radioecology, Analysis of trace elements, Health Physics
Radionuclide, Radiocaesium, 90Sr, Speciation of radionuclides, Soil, Crops, Agricultural water, Reservoir bottom sediment
Radionuclides released into the environment transfer through various processes, being affected according with the existence forms. Therefore, to grasp the behavior of radionuclides, it is necessary to study on speciation as well as transferring amount.
I have so far conducted research in the field of Environmental Radioecology, with the focus on dynamics of radionuclides mainly in the terrestrial environment. In the current research, I work to clarify the existence forms of radionuclides (mainly radiocaesium and 90Sr) in the terrestrial environment, elucidating and analyzing their dynamics in soil-plant system, land water and their related factors.
A few words
Environmental Radioecology is a comprehensive academic field that combines various research fields such as analytical chemistry, geochemistry, environmental chemistry, and biology, etc. With my experience and knowledge, I have been engaged in the following activities after the TEPCO Fukushima Daiichi Nuclear Power Station accident.
Immediately after the accident from March to July 2011, in cooperation with several researchers, I continued to post and update “Information on the nuclear accident” in a website of Japanese Society of Soil Science and Plant Nutrition. At that time, much confused information on the radionuclides dynamics were spreading around but our information at the website was used many times as information based on academically correct knowledge. The information we updated was finally published in Japanese Journal of Soil Science and Plant Nutrition 82 (2011) 408-418. In addition, as a commentary for the general public, I disseminated information on the dynamics of radiocaesium in soil and its transfer in soil-plant system.
In 2012 to 2013, I joined Fukushima Future Center for Regional Revitalization at Fukushima University. Since 2014, I have belonged to IER to conduct studies in Fukushima Prefecture as my research fields. I am aiming to face the challenges of Fukushima Daiichi Nuclear Power Station accident by elucidating the dynamics of radionuclides in the environment. As a citizen of Fukushima, being closely related to the future of this place, I hope to disseminate scientific and universally correct data from Fukushima.
