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 applied will be shown. A short outline of the course is given below.

Lecture content

Part I

Introduction to radioactivity and radioactive decay

Formation of Earth and the elements

Natural radioactivity

  • Primordial radionuclides
