How can I protect myself from radon?

If there is too much radon in your house, regular intensive ventilation can help in the first instance. The high radon concentrations usually arise because soil air containing radon penetrates from the building subsoil. Because of this

• new buildings should be sealed against ground humidity and therefore against radon penetration and
• unsealed points in existing buildings should be identified and sealed.

The suctioning of soil air containing radon from beneath or beside buildings can also help, as can the installation of technical ventilation systems. Only measurements can show whether the concentration of radon in a building requires protection measures.
