Air surveillance
For the monitoring of radioactivity in the atmosphere, the URA section operates, in addition to the UraNet network, other sampling systems allowing to reach a very low detection limit (high sensitivity measurements).
High Volume Sampler
Since 1993, the URA section has maintained a network of high-flow aerosol collectors. Currently, six stations are in operation:
No trace of iodine-131 in January air samples in Switzerland.
