Quebec Radon Map: Risk area map and complete guide
Radon, a natural radioactive gas, is a major public health issue in Quebec. Invisible and odorless, it can accumulate in homes and increase the risk of lung cancer. Thanks to the Quebec Radon Map, it is possible to identify areas where high concentrations have been measured.
In summary: the map identifies statistical zones, but regardless of the region, all homes can have a high level of radon. Testing your home remains the only reliable method, and if levels are high, a mitigation solution exists.
Why the Quebec Radon Map is important
The Quebec Radon Map is an interactive tool developed by the Quebec Lung Association. By entering a postal code, users can consult available regional data concerning radon.
The Quebec radon map identifies risk areas, but every home is unique. Even in a low-risk area, high concentrations can be measured.
Even in a low-risk area, a home can exceed 200 Bq/m³.
👉 1 in 5 homes in Quebec is at high risk.

What is radon and why worry about it?
Radon comes from the natural disintegration of uranium present in the soil. It can infiltrate buildings through foundation cracks, drains, or joints. When it accumulates to high levels, it becomes a significant cause of lung cancer.
Consulting a radon map in Quebec is a first step, but it does not replace an actual test in your home. Each property is different and can have a unique level.
Some key statistics
- About 1,000 deaths per year in Canada are linked to radon.
- Nearly 1 in 5 homes in Quebec exceeds 200 Bq/m³.
Home tested: 380 Bq/m³
After mitigation: 45 Bq/m³
✔ Fast and lasting reduction
✔ Installation in one day in most cases
👉 A solution exists if your level is high.

How to test your home for radon
- Order a certified radon detector.
- Perform the measurement according to the recommended protocol.
- Take action if the threshold of 200 Bq/m³ is exceeded.

Don't take unnecessary risks
Radon is invisible, but its effects are very real.

Can all homes in Quebec have radon?
Yes. Regardless of the region or type of building, any home can have a high level of radon. The only way to know is to measure it directly in your home.
What is a dangerous radon level?
Health Canada recommends intervening when the concentration exceeds 200 Bq/m³. However, it is preferable to reduce radon to the lowest possible level.
How much does a radon test cost?
A certified radon detector is generally affordable and allows you to obtain a representative measurement for your home.
How to reduce radon in a home?
The most effective method is to install an active sub-slab depressurization system, which captures radon from under the foundation and vents it outside.
