Question 2: Where are Radon-affected areas?

Radon is found in small quantities in all soils and rocks, although the amount varies from place to place, depending on the geological underground. Radon from the ground is drawn through openings, cracks and gaps into buildings, like homes, offices, schools, kindergartens.

Measurements in Europe, like in Germany, Austria and Italy, show Radon levels varying not only between different parts of the country but even between neighbouring buildings.
