It is very important to understand the impact for CTBT stations caused by radioxenon emitted from nuclear facilities and medical isotope production facilities for detection of underground nuclear tests. Predictions of the impact on the CTBT radionuclide station in Germany of radioxenon emitted from the medical isotope production facility in Belgium were carried out by participants from seven nations using ATM (Atmospheric Transport Modeling) based on the emission data of radioxenon from this facility, as part of study on impact of radioxenon emitted from medical isotope production facilities on CTBT radionuclide stations.
