Lecture: Radioecology

The Radioecology lecture is part of the module "Umwelt- und Actinidenchemie" (Chem-Ma-M06). Lecture topics on environmental radioactivity deal with e.g. sources of radionuclides in the environment, factors influencing radionuclide migration and uptake in food chains and our ecosystems, sampling and pre-treatment of environmental samples, and radionuclide separation methods. In addition, examples on how radioecology is present in every-day life are given. A short outline of the course is given below.
