Noémi M. Nagy is a professor of radiochemistry in the Imre Lajos IsotopeLaboratory of Physical Chemistry, University of Debrecen, Hungary. She earned herM.Sc. and Ph.D. degrees in radiochemistry at that university. She has a D.Sc. degreein agrochemistry from the Hungarian Academy of Sciences. Dr Nagy has more than35 years of experience in nuclear and radiochemistry teaching. Her research interestis the study of the interfacial processes of natural sorbents, including soils, rocks,clay minerals mainly by radioactive tracer methods. Recently, she has been dealingprincipally with studies of nuclear waste storage. She has written or co-writtennumerous peer-reviewed scientific papers and is the co-author four books in thefields of nuclear and radiochemistry as well as the interfacial chemistry of geologicalformations. She won the George Hevesy’s award for nuclear safety in Hungary.Dr Nagy is the president of the Radiochemical Scientific Committee of HungarianAcademy of Sciences.József Kónya is a professor of radiochemistry in the Imre Lajos Isotope Laboratoryof Physical Chemistry, University of Debrecen, Hungary.
