Monitoring station Schauinsland: history and tasksmission

1946, a group of scientists from the Institute of Physics of the Albert-Ludwigs-University in Freiburg began to conduct experiments to characteris the cosmic radiation on Mt Schauinsland in the Black Forest. 1953, the researchers for the first time succeeded in detecting fallout from nuclear weapons tests in precipitation samples. As a result, a permanent monitoring station was built on Mt Schauinsland for the continuous long-term monitoring of the atmosphere for artificial and natural radioactivity. In 1957 the station began operation. Today the station is also part of the International Monitoring System (IMIS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) adopted by the UN.

Trace analysis worldwide

The international Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has a worldwide network. Once fully completed it consists of 80 radionuclide measurement stations for detection of radionuclides bound to airborne dust. In addition 40 of these stations are equipped with systems for the measurement of radioactive xenon (xenon-133).

One of these radionuclide measurement stations is operated by the Federal Office for Radiation Protection (BfS) on Mt Schauinsland near Freiburg im Breisgau.
