Christian Ole Lind (Norwegen): Atmospheric Transport and Environmental Behaviour of Radioactive Particles

A multitude of past, present and future sources of radioactivity have contributed, or have the potential to contribute to radioactive contamination of the environment. A significant fraction of the radionuclides released from nuclear events such as nuclear weapon detonations and nuclear accidents will be in the form of radioactive particles. The characteristics of such particles are source related and release scenario dependent. Thus, they carry information about the source and the event.
Since particle characteristics influence environmental transport, particle weathering rates, mobilisation, ecosystem transfer and dosimetry, the knowledge of particle properties such as radionuclide and stable element composition, size and density can reduce uncertainties in impact assessments.
This seminar focuses on research performed to quantify and reduce uncertainties in various radioecological models with emphasis on radioactive particles and the use of state-of-the-art analytical techniques.
