Radon-safe construction.
What is radon?
What is radon? What makes it so dangerous? And what is the remedy? Our explanatory video will provide you with the most important facts about the naturally occurring radioactive noble gas and show you how you can protect yourself against it.
The most important facts about radon:
- Statutory reference value for the annual average radon concentration in the air in indoor spaces and at workplaces: 300 Bq/m3
- Measures required in accordance with the general rules of technology for humidity protection are considered suitable preventative measures against the ingress of radon into buildings.
- The radon concentration in the soil vapour may vary between regions and seasons.
- Radon experts help to determine the radon level and position the appropriate measuring devices (exposimeters). Following this they also provide assistance with defining necessary measures.
- Radon is the second most frequent cause of lung cancer after smoking.
- The radioactive noble gas blends with the ambient air outdoors and is therefore quite safe.
- Everyday tip: Aerating thoroughly and regularly reduces the radon concentration.

Radon map of Germany
The radioactive noble gas occurs in concentrations that differ from one region to the next. The radon map of Germany published by the Federal Office for Radiation Protection (BfS) in 2004 shows the areas in which there are increased radon levels.
This is based on very approximate grid measurements of the radon concentration in the soil air as well as in building interiors and outdoors. Although radon blends with the air outdoors, it can still be detected at ground level. Higher concentrations of radon are particularly noticeable in the mountainous regions of Germany.
Statutory reference value for the annual average radon concentration in the air in indoor spaces and at workplaces: 900,000 radon particles can enter a house at the same time through a hole the size of a pinhead.
Radon was discovered in 1900. However this noble gas has been in existence since the beginning of time.
Danger posed by rectangular recesses
Rectangular recesses in the floor slab, as are still sometimes created today for wastewater entries, are not state of the art and do not protect the building adequately against the ingress of gas. The same applies to incorrectly sealed building entries.
See for yourself.
Safe from radon with correct sealing
Choosing the right solutions is crucial for reliable protection when it comes to sealing supply and disposal lines. Professional solutions for entries both for supplying a building and for wastewater disposal are therefore important factors when planning and constructing a building.
