Radon is quite widespread in Estonia, due to complicated geological conditions caused by
the appearance of tectonic cracks, graptolitic argillite, phosphorite and also uranium in some places. Geological Survey of Estonia
mapped radon priority areas and Radon Risk Atlas was published, according to this 1/3 of the entire territory is a radon risk area.
