FAQ

What does the radon potential classification mean?▾

The radon potential indicates the likelihood that buildings in this area will have elevated radon levels, based on geological and measurement data from official authorities. It does not predict the level in any individual building.

Is measurement mandatory here?▾

It depends on the national regulations and the type of building. In priority action zones, measurement is often mandatory for workplaces and public buildings. For dwellings, measurement is generally recommended. Check the obligations section above for details specific to this country.

What should I do if the level is above the reference level?▾

If your long-term measurement exceeds the national reference level, mitigation measures such as sub-slab depressurization, sealing or improved ventilation can reduce radon levels significantly. Contact a qualified radon professional.
