Protection against radon
Radon – the invisible danger from the ground
Radon is invisible, odourless and tasteless. But its radioactive decomposition products are dangerous: If the concentration of radon in an inhabited building is too high, it can build up in the lungs and lead to lung cancer. In simple terms the situation can be described as follows: «There are laws but no-one pays any attention to them». Radon and/or its decomposition products are a ticking time bomb for owners and tenants.

Conclusion for responsible builders and owners
Radon causes lung cancer and is found everywhere in the ground. No two houses are the same and a measurement is necessary in order to be establish the facts. Building measures can resolve the radon problem and safeguard the value of a property.
Solutions
1. Radon-proof construction measures
- Seal all cracks and joints in the floors and walls that are in direct contact with the soil or ground below
- Seal all the conduits for wiring
- Install a radon-proof division between the inhabited and the uninhabited areas
- Floor slabs instead of strip foundations
