WHAT IS RADON?
Radon is a naturally occurring radioactive gas that can enter homes from the soil through cracks, sump pits, penetrations and even the concrete basement slab.
KEY THINGS TO KNOW
- You can’t see, smell or taste radon — testing is the only way to know.
- Any home can have elevated radon, including new homes.
- Radon levels fluctuate. Long-term testing of at least 91 days provides the best representation of average exposure.
- Long-term exposure is the leading cause of lung cancer in Canadian non-smokers.
- Health Canada’s action guideline is 200 Bq/m³. Elevated radon levels can usually be effectively reduced with professional mitigation.
