What is radon? Radon is an often underestimated health risk

Radon is a radioactive noble gas and occurs in varying concentrations in all soils. Radon can penetrate buildings from the ground. If it accumulates in closed rooms, high concentrations of radon can develop there, which can cause lung cancer in the occupants.

Formation of radon

Radon is produced by the radioactive decay of uranium, which is found in all rocks and soils. Radon escapes from the ground into the open air and into buildings.

In the open air, radon dilutes quickly so that the radon concentration there is low and harmless to health.
