Reading this page

In Kelowna, the published mean indoor radon reading is 135.3 Bq/m³, based on Health Canada survey sampling from 106 home readings in the Kelowna metropolitan area. 15.1% of tested homes in this sample exceed the 200 Bq/m³ guideline, and the highest single reading recorded was 1174 Bq/m³.

Local geology is recorded as mixed. Geology helps explain regional averages; individual homes still vary with foundation type, ventilation, and soil contact, so a moderate regional average does not rule out a high reading in any single home.

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 Kelowna

Kelowna 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.

Testing strongly advised

15.1% of tested homes in this area exceed 200 Bq/m³. Individual homes vary — the only way to know your level is to test.

1Order a Health Canada approved long-term test kit
2Place the detector on the lowest occupied level for 3+ months
3Send the kit to the lab and compare results to 200 Bq/m³
4Retest every 2 years or after major renovations

Order a long-term radon test kit

Average indoor radon in Kelowna is 135.3 Bq/m³, and 15.1% 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.
