Around 1,000 people gathered at the stands in the mechanical engineering department of the Technical University of Munich (TUM) on German Unity Day. In addition to the FRM II research neutron source and the Heinz Maier-Leibnitz Zentrum, ITM Radiopharma, the Gesellschaft für Nuklear-Service, and the TUM School of Natural Sciences also presented themselves here. Particularly popular were the two experimental lectures in physics and chemistry, each with 400 spectators, and the guided tours of the FRM II research neutron source, which were attended by a total of 246 adults and 88 children.
