Ludwig Feinendegen, M.D., former director of the Department of Nuclear Medicine, University Hospital, Heinrich Heine University Duesseldorf, Germany, 2010 Marie Curie Prize - Jerry Cuttler, D.Sc. in nuclear sciences and engineering, recipient of 2011 International Dose-Response Society Award for Outstanding Career Achievement: There is considerable controversy regarding risk of health detriment after low-level exposure to ionizing radiation.
