Saharan dust events contribute to the aerosol load over Switzerland, mostly during spring and autumn. These events can be detected accurately with continuous measurements at the Jungfraujoch and at the aerological station in Payerne. …….
The nuclide-specific monitor at the Fribourg station was moved to Mühleberg at the beginning of February. For this reason, no new measured values will be displayed at the Fribourg station.
The new automatic network for monitoring airborne radioactivity operated by the Federal Office of Public Health (FOPH) is operational. It replaces the old network, which was put in place after the Chernobyl accident and became obsolete. This network makes it possible to identify and quantify radionuclides in the air and to generate an alarm if set thresholds are exceeded.
