New automatic network for measuring radioactivity in the air in Switzerland
The new automatic network for monitoring airborne radioactivity operated by the Federal Office of Public Health (FOPH) is operational.

This network makes it possible to identify and quantify radionuclides in the air and to generate an alarm if set thresholds are exceeded.
