Further more to this list of towns, radon concentration is high in:
- air permeable slack or sand formations all over the country
- underground estates
- ridge areas
Because noxious radon appear all over Finland, it is justified and reasonable to measure all livable properties for radon.
Radon measurements in nearby properties should not be taken as a reliable result for neighborhood. Every house and property should be measured.

The list of noxious radon areas is updated by STUK. Measurements of sufficient areal samples and results define the areas.
We recommend measurements all over in Finland. Radon is a problem everywhere, so only measured results are reliable.
