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.
