Radon in the canton of Neuchâtel

Radon in the canton

The national map shows the probability of exceeding the reference level, not the concentration in your home. Ground conditions, air entry routes and construction mean that conditions vary from one building to another. Measurements in occupied rooms are still needed to assess your exposure, even if a neighbour already has a result.

Building or renovating in Neuchâtel

The Service de l’énergie et de l’environnement (SENE) provides cantonal information and the radon commitment form for construction or alteration projects. Check with your municipality which documents your application requires. Planning pipe routes, airtightness and ventilation in advance allows radon protection to be built into the project before work begins.

Support from Corcelles

If you have no previous measurements, we consider the location, building, occupancy and your timeframe to suggest a suitable approach. If you already have results, we start by reviewing them.

An in-depth survey involves approximately one week of simultaneous measurements in rooms in contact with the ground, with additional measurements on upper floors where needed. It provides the basis for solutions where the findings warrant action.

Preparing your enquiry and the next steps

Tell us the municipality, building type, number of rooms and other spaces in contact with the ground, your objective and timeframe. Include any results or documents received from the authorities if available; you can also send these after the first contact.

If mitigation is needed, Robert prepares the proposal and carries out the work. Monitoring before and after the work, the mitigation report and confirmation using passive detectors are all part of the same service.
