Order radon dosimeter

So that you know where to expect RADON

Measuring point recognized by the FOPH

Since January 1, 2018, a new radon reference value of 300 Bq/m³ (previously 1000 Bq/m³) has applied in Switzerland in accordance with the new Radiation Protection Ordinance. This emphasizes the increased importance of managing radon exposure throughout the country. The average radon gas concentration over the year should not exceed this reference value in rooms where people regularly spend several hours a day. With the help of dosimeters (short-term or long-term measurement), the radon concentration in indoor air can be measured easily and inexpensively.

Ecosens AG is a measuring station for radon recognized by the Federal Office of Public Health (FOPH).
