Areas requiring radon measurements in workplaces

Areas requiring radon measurements in workplaces

Radon concentrations greater than the reference value in workplaces can be predicted on the basis of previous radon measurements in dwellings and workplaces.

According to section 155 of the Radiation Act, radon concentration at workplaces must be determined in areas where more than 10 per cent of the radon concentrations measured earlier in apartments, other living areas and workplaces exceeds the value of 300 Bq/m³. At the tables below are listed all such areas.

Check if your workplace is either on the list of municipalities or postcodes

The tables include areas where thirty or more measurements have been made. Note that the areas where radon measurements are to be performed are defined both as municipalities and as postal code areas outside these municipalities.
