Radon is a naturally occurring radioactive gas that forms when uranium in soil, rock, and water breaks down. It is colorless, odorless, and tasteless, making it impossible to detect without specialized equipment. While it’s present in low levels outdoors, radon can accumulate to dangerous levels indoors, posing serious health risks.

In Canada, radon is the second leading cause of lung cancer, responsible for about 16% of cases. When radon gas is inhaled, its radioactive particles can damage lung tissue, increasing the risk of lung cancer over time. The risk is especially high for smokers exposed to elevated radon levels.

Radon enters homes through cracks in foundations, floors, walls, and gaps around pipes. Basements and ground-level rooms are most vulnerable, but any home, new or old, can have radon problems. Poor ventilation can allow radon to build up, creating hazardous conditions for occupants. Testing is the only way to know if your home has elevated radon levels.
