Radon Health Facts
Health Impact
Radon is the second-leading cause of lung cancer after smoking, accounting for about 16% of lung cancer deaths in Canada annually.
Geographical Variations
Certain regions, such as Monitoba, Saskatchewan, New Brunswick and parts of British Columbia and Quebec, have higher radon prevalence.
Recent Findings
A 2023 study indicates that nearly 17.8% of Canadians live in home with dangerous
Testing Recommendations
Health Canada recommends that all homes be tested for radon, regardless of geographic location or foundation type.
Increased Risk for Smokers
Smokers exposed to elevated radon levels have a significantly higher risk of developing lung cancer compared to non-smokers.
Detection Necessity
Radon is a colorless, odorless, and tasteless gas, making testing the only way to detect it’s presence in homes.

Everything You Need Know
What is short-term radon test?
What is a long term radon test?
Why should I get a short-term test instead of waiting 91+ days?
✅ You need fast results – If you’re buying or selling a home, you can’t wait months.
✅ It gives a strong indication of risk – High radon levels in a short-term test mean immediate action is needed.
✅ It’s ideal for initial screening – If elevated, a long-term test can confirm trends.
How do radon levels fluctuate over time?
Radon levels are not constant—they can change due to weather, ventilation, and seasonal factors.
During the heating season (fall & winter), radon levels are often higher because:
✔ The Stack Effect: Warm air rises inside the home and escapes through the roof, creating a vacuum effect that pulls more radon from the ground into your home.
✔ Less Ventilation: Windows and doors stay closed longer in colder months, trapping radon inside.
✔ Frozen Ground: In some areas, the ground outside freezes, forcing more radon to enter through foundation cracks.
This is why radon levels often spike in winter and why a long-term test (90+ days) gives the best year-round measurement.
What is considered a dangerous radon level?
• Health Canada Action Level: 200 Bq/m³ (Becquerels per cubic meter) – Homes at or above this level should take action.
• World Health Organization (WHO) Guideline: 100 Bq/m³ – WHO recommends mitigation at this lower level.
• U.S. Environmental Protection Agency (EPA) Guidelines: 148 Bq/m³ and is used as the U.S. action level.
Even low radon levels carry some risk, but the higher the concentration, the greater the chance of developing lung cancer over time.
What happens if my home has high radon levels?
Do newer homes have higher radon levels?
Does my home insurance cover radon mitigation?
Can radon levels vary between houses in the same neighborhood?
Yes! Even if your neighbor’s home has low radon levels, your home could still have high radon due to differences in:
✔ Soil composition under your home
✔ Foundation cracks & construction materials
✔ Ventilation & air pressure in your home
The only way to know is to test your home!

How does radon enter a home?
Radon comes from the natural breakdown of uranium in soil and rock. Since it’s a gas, it seeps into homes through small openings in the foundation and structure.
🚪 Common entry points include:
✔ Cracks in foundations, basement floors, and walls
✔ Gaps around pipes, drains, and sump pumps
✔ Crawl spaces with exposed soil
✔ Poorly sealed construction joints
✔ Well water (in rare cases, radon can be released from groundwater into indoor air)
Once inside, radon accumulates, especially in basements and lower levels, and can reach dangerous concentrations if not properly ventilated.
When is the Best Time to Test for Radon?
Radon can be tested any time of the year, but the best time to test is during the heating season (October–March).
Why?
✔ Higher Radon Levels in Winter: During colder months, homes are sealed up, windows stay closed, and the stack effect pulls more radon inside.
✔ More Accurate Results: Since radon levels are usually at their peak in winter, testing during this time gives a worst-case scenario reading, ensuring your home is safe year-round.
✔ Less Air Circulation = Higher Readings: Using furnaces, fireplaces, and exhaust fans can create negative pressure, drawing in more radon from the soil.
If you test outside the heating season, consider a long-term test (90+ days) to account for seasonal variations.
🚨 No matter the time of year, the most important step is to test! 🚨
Should I test for radon before buying a home?
Do condos and apartments need radon testing?
Yes! Radon can accumulate in multi-unit buildings just like in single-family homes, and it doesn’t stay confined to one area.
✔ Ground-floor and basement units are at the highest risk since radon enters from the soil beneath the building.
✔ Radon can travel between units through shared walls, ventilation systems, plumbing, and electrical openings.
✔ Elevator shafts and stairwells can act as radon pathways, allowing the gas to rise to upper floors due to the stack effect.
✔ Some provinces require radon testing in multi-unit buildings to protect occupants from long-term exposure.
💡 The only way to know if your unit has high radon levels is to test—regardless of which floor you live on!
