Potential exceedance of the reference value of radon concentration in buildings? Radon map (FOPH)

Radon is a naturally occurring, radioactive noble gas, which can seep into buildings through the ground. Switzerland is particularly affected by this problem due to its geology. The radon map indicates the probability (in %) of exceeding the reference value of the radon concentration of 300 Bq/m3 in a building.

Geoinformation and health

What is the concentration of noxious emissions and allergens in a particular place? In which region and how quickly does a disease or virus spread? In the health sector, as in other areas, geoinformation helps to understand interrelationships and dynamics and to find answers to a wide variety of questions.
