The Rossendorf Beam Line ROBL - a dedicated experimental station for XAFS measurements of actinides and other radionuclides

X-ray absorption fine structure (XAFS) spectroscopy is a powerful tool for obtaining basic molecular-level information, which is required for a better understanding of the mechanisms responsible for radionuclide transport in the environment. A unique experimental station dedicated to the study of ac tinides and other radionuclides by XAFS spectroscopy has become operational at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The main characteristics of the Rossendorf Beamline, ROBL, and its radioch emistry end station and selected results obtained on Tc and Np solutions ar e presented.
