About RADON

Radon is a clear, colourless, and radioactive gas.
It is produced by the natural radioactive decay of uranium found in soil and bedrock.

Radon in your home can be a serious concern - it is the second leading cause of lung cancer in Canada.
Any crack, gap, or discontinuity in the foundation wall or slab can serve as a potential entry point for radon.

Radon intrusion is typically greatest during the heating season. As warm indoor air rises, it draws replacement air from below the structure - potentially from the soil beneath the building.
This stack effect, combined with closed-building conditions during the colder months, is why Health Canada recommends performing a long-term radon test (minimum 90 days) between October and April.

It is the radioactive decay products of radon that pose health risks. Radon decay is measured in units of becquerels (Bq), where one becquerel equals one radioactive decay per second. The higher the radon concentration, the greater the number of decays - and thus, the higher the becquerel level.

Health Canada recommends taking remedial action when radon concentrations exceed 200 Bq/m³.

The only way to know your home’s RADON level is to test.
