Legal dispositions concerning radon

As from 1.1.2018, the limit value of 1000 becquerels per cubic meter (Bq/m³) is replaced by a reference level of 300 Bq/m³ for the average annual concentration of radon gas in "premises where people stay regularly for several hours a day". In addition to this reference level, a threshold value of 1000 Bq/m³ is applicable for the average annual concentration of radon gas at workplaces exposed to radon.
