How is radon measured?

Measuring radon is very simple and does not require any intervention in the room.
📦 When you receive the detector, simply place it in the room where you want to measure (e.g., basement, bedroom, living room).

🔌 Plug the detector into a power source, wait a few minutes, and the recording of values will begin.
⏱️ The first result is visible after just 10 minutes, while more accurate insights are obtained after several hours or days of measurement.

 

We measured elevated radon concentrations – what now?

 

Almost all homes with excessive radon levels can be remediated, sometimes with very simple and inexpensive measures. The cost of remediation can range from nothing to a few thousand euros. Check whether the average radon concentration in your home exceeds the reference value of 300 Bq/m³, and we will help you find the most suitable solution for your building. With us, you can rent or purchase a radon detector.

 

If you are buying a property, we recommend measuring radon before purchase. You may be able to negotiate a better price if the property is exposed to high radon levels and no mitigation measures have been implemented.

 

What can we do to reduce radon concentrations?

 

Ventilation of rooms
When radon levels are only slightly elevated (up to 400 Bq/m³), especially in rooms where you do not spend much time, ventilation alone can be sufficient. Several times a day, open windows for a few minutes to equalize the radon concentration in your home with the outside air. However, the concentration may return to near the reference value within 3 to 6 hours.

 

Remediation or sealing of the foundation slab
If ventilation alone does not achieve the desired effect (at concentrations above 400 Bq/m³), it is necessary to identify and seal the entry points of radon into your home. These are often larger openings in the floor slab, which the homeowner usually knows about (such as shafts, larger cracks, etc.).

 

Ventilation of soil and sub-slab depressurization
At higher radon concentrations (above 1000 Bq/m³), room ventilation and sealing of the slab are rarely sufficient. Significant reduction of radon levels (even over 90%) can be achieved by extracting air from beneath the foundation slab. This solution includes one or more pipes that draw air from under the house’s slab (accessed by drilling through the slab or from the outside) and release it above the living space. Ventilation can be passive, relying on natural air pressure differences (stack effect), or active with fans, which usually consume little electricity.
