Radon map of Switzerland

The concentrations of radioactive noble gas differs from region to region. The radon map shows the probability[%], that the Reference value of 300 Bq/m3 for radon concentration in buildings is surpassed. The map helps determine the necessity of measuring the radon level in a building. For the measurement, survey institutes authorised by the Bundesamt für Gesundheit BAG can be contacted.

300Bq/m3

Statutory reference value for the annual average radon concentration in the air in indoor spaces and at workplaces: 900,000 radon particles can enter a house at the same time through a hole the size of a pinhead.

Radon was discovered in 1900. However this noble gas has been in existence since the beginning of time.

Buildings without a basement

Radon can penetrate into a building through the smallest of cracks.
