Radon is a natural radioactive inert gas which is formed from uranium in the soil. It enters a building via the ground and can accumulate there. The gas is neither detectable by smell nor by taste.
An accumulation of radon in frequently used rooms can entail a significantly increased risk of cancer. Radon is the second-most common cause of lung cancer after smoking.
Whether or not radon enters and accumulates in a building depends on the natural uranium concentration in the soil but also on the permeability of the subsoil, the groundwater situation and the building itself. The age and condition of the construction materials (joints, cracks, fissures), the type of foundation and the presence of sealing materials also play a part. Sumps, pipe penetrations and ducts can be routes of entry for radon, too.
Therefore, the question whether a radon problem exists in a building or whether there is a health risk is always a case-to-case decision. Radon measurement and an evaluation of the construction materials with regard to a potential hazard from radon by an LGA expert help to avoid unnecessary risks.
Our services to you include:
- Research on the radon situation in the investigated area
- Inspection by an expert and setting up a sampling plan
- Technical investigation (radon overwiew measurements and search for the routes of entry)
- Soil gas investigations (subsurface investigation with regard to radon)
- Risk assessments with regard to radon
- Assessment of the existing construction materials with regard to radon protection
- Counseling on precautionary radon protection in new buildings
