Radon in Saguenay
Quebec, Canada
Geological Context
Location and surrounding area
Estimated radon potential
HighEstimate based on the bedrock under the city (Global Lithological Map): granite-type and acid volcanic rocks carry more uranium. It is not an official classification. Only a measurement gives the radon level of a building.
What the regulations require
Dwellings
Guideline 200 Bq/m³ for homes, offices and schools (Health Canada, not legally binding federal law). Measurement and mitigation recommended if exceeded.
Workplaces
Employers must measure if radon exceeds 200 Bq/m³. Mitigation recommended. Occupational exposure governed by provincial regulations.
New construction
National Building Code (2020) requires radon protection measures in new buildings in radon-affected areas: soil gas barriers, rough-in provisions.

What should you do?
Regardless of the official classification, the only way to know the radon level in a specific building is to measure it. A long-term test (at least 3 months) is recommended. You can either test yourself with passive detectors or hire a certified professional.
FAQ
What does the radon potential classification mean?▾
The radon potential indicates the likelihood that buildings in this area will have elevated radon levels, based on geological and measurement data from official authorities. It does not predict the level in any individual building.
Is measurement mandatory here?▾
It depends on the national regulations and the type of building. In priority action zones, measurement is often mandatory for workplaces and public buildings. For dwellings, measurement is generally recommended. Check the obligations section above for details specific to this country.
What should I do if the level is above the reference level?▾
If your long-term measurement exceeds the national reference level, mitigation measures such as sub-slab depressurization, sealing or improved ventilation can reduce radon levels significantly. Contact a qualified radon professional.
