November is Radon Action Month and Huron Perth Public Health is encouraging residents to test their homes.
Radon, an odourless, colourless, and tasteless gas is produced by the decay of naturally occurring uranium in the soil and rocks.
The gas can travel into homes through cracks in foundation floors, gaps around pipes or cables, or sumps and drains.
Long-term exposure to higher levels of radon is the second-leading cause of lung cancer after smoking.
Radon gas can be found at low levels in many homes across Ontario.
They recommend residents test their homes for radon using a long-term test. A long-term test monitors indoor air for a minimum of three months.
The Canadian Guideline for radon is 200 Bq/m3 (becquerels per cubic metre).
