Tateda, Yutaka
Dr. Yutaka Tateda, scientist at the Environmental Science Research Laboratory of the Central Research Institute of Electric Industry (CRIEPI) in Abiko, Chiba. He is internationally recognized expert with over 40 years of experience in investigations of marine radioecology. He was Visiting Scientist at the National Institute of Radiological Science Japan, especially studying the experimental application of radiotracer to clarify the bio-kinetics of radionuclide and the corresponding trace element behaviors in marine biota and environment. In addition, he was Visiting Scientist at the Marine Environmental Laboratory of the IAEA in Monaco, responsible for the sediment trap study evaluating the natural radionuclide flux and inventory in coastal ecosystem. He also led international projects on application of natural radionuclides to evaluate the carbon budget in coastal ecosystem not only in marine but also of terrestrial biota with several Asian countries. After his return to the CRIEPI, he established the dynamic biological transfer model for evaluation of radionuclide distribution between biota and environment under transient state, e.g., for the unexpected accidental emergency case. After 2011, he has been successful on understanding of environmental impacts of the Fukushima accident on marine ecosystems by his accumulate research carrier. He published more than 100 scientific papers with more than 500 citations (Google Scholar).
Povinec, Pavel P.
Prof. RNDr. Pavel P. Povinec, DrSc., Professor at the Faculty of Mathematics, Physics and Informatics of the Comenius University in Bratislava, retired Head of the Radiometrics Laboratory of the IAEA-MEL in Monaco, former Head of the Department of Nuclear Physics and Vice-Dean of the Faculty of Mathematics and Physics. He is recognized expert with over 50 years of experience in low-level radioanalytical and nuclear science (rare nuclear decays), in environmental (radionuclides as tracers, radiocarbon dating), and space physics (radionuclides in lunar samples and meteorites). At IAEA-MEL he was responsible for the development of radiometric (including underground laboratory) and mass spectrometry methods (ICP-MS, AMS) for marine radioactivity studies. He led several international projects on assessment of dumping of radioactive wastes, on impacts of nuclear weapon test sites, on worldwide marine radioactivity studies (WOMARS), on submarine groundwater discharge studies (SGD), on the development of global marine radioactivity databases (GLOMARD/MARIS), etc. After his return to the Comenius University, he established at the Faculty of Mathematics, Physics, and Informatics a Centre for Nuclear and Accelerator Technologies (CENTA) focusing on the development of IBA and AMS methods and their wide applications in nuclear, material, environmental, and biomedical sciences. In recent years he has been focusing on assessment of environmental impacts of the Fukushima accident. In 2017 he got Hevesy Medal Award for his contribution to nuclear sciences. He published more than 20 books and book chapters and more than 700 scientific papers with more than 12,000 citations (Google Scholar), organized more than 20 international conferences, and delivered more than 50 invited talks.
