Lecture: Radioecology

The Radioecology lecture is part of the module "Umwelt- und Radiochemie". 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, radionuclide separation methods and specific counting techniques for low-level samples. In addition, examples on how radioecology is present in every-day life are given. A short outline of the course is given below.
