Reading this page

In Victoriaville, average indoor radon is 40.6 Bq/m³ (below the Quebec average of 101 Bq/m³). 0% of tested homes exceed Health Canada's 200 Bq/m³ reference level.

Local geology (Mixed) contributes to regional variation. Geology helps explain area averages; individual home levels still depend on foundation type, ventilation, and soil contact.

How to read this

Figures come from Health Canada's Cross-Canada Survey of Radon Concentrations in Homes: long-term tests in participating dwellings, aggregated by geography. The 200 Bq/m³ guideline applies to the normal occupancy area (lowest lived-in level). A city mean is not a reading for your address.

Start with the mean and the share of homes at or above 200 Bq/m³, then check whether this page is labeled direct or regional. Direct means the survey geography matches this municipality or its named metro breakout. Regional means you are seeing a broader area average that may not match your street. Compare with the provincial reading only as context; house-to-house variation is usually larger than city-to-city gaps.

Prefer a three-month (or longer) alpha-track test that includes heating season. Short-term tests are screening tools. Place the detector on the lowest lived-in level, away from exterior walls and high airflow. For elevated results, hire a C-NRPP measurement or mitigation professional, then retest after any work.

Mixed beneath Victoriaville

Victoriaville sits on Mixed bedrock or surficial deposits. Radon enters homes through cracks in foundations, sump pits, and utility penetrations. Geology explains regional averages, but individual home levels depend on construction, ventilation, and soil contact.

Test to confirm your level

Regional averages are moderate, but radon varies house to house. Health Canada recommends all Canadians test their homes.

  • 1Use a long-term test kit during heating season (October–April)
  • 2Place the detector away from drafts, windows, and exterior walls
  • 3If results are below 200 Bq/m³, retest every 2 years
  • 4If results exceed 200 Bq/m³, consult a C-NRPP certified mitigator

Test your home anyway

Average indoor radon in Victoriaville is 40.6 Bq/m³, and 0% of tested homes exceed the 200 Bq/m³ guideline. A three-month alpha-track test on the lowest occupied level is the right first step.
