The radon map indicates the probability [%] of exceeding the reference value of the radon concentration of 300 Bq/m3 in a building.
Probability [%] of exceeding the reference value:
Existing buildings: Only a measurement can determine the radon concentration in a specific, existing building. The list of approved measuring services is available below (see "Documents").
New buildings: The FOPH recommendations concerning radon protection in new buildings (see "documents" below) are currently being updated. In addition to the building characteristics, it is planned to also consider the probability of exceeding the reference value of 300 Bq/m3 corresponding to the new radon map.
