What is radon gas?
Radon is a colourless, odourless, radioactive gas that can cause lung cancer. (Public Health Ontario)
Radon can be found in buildings (e.g. homes, schools, and offices) and is formed by the breakdown of uranium, a natural radioactive material found in soil, rock and groundwater.
When radon is released from the ground into the outdoor air it gets diluted to low concentrations and is not a concern. Radon can sometimes accumulate to elevated levels in enclosed spaces like homes, which can present a health risk with long-term exposure.
Cross-Canada Survey of Radon Concentrations in Homes - Results
Here you will find a summary of the results from the Cross-Canada Survey of Radon Concentrations in Homes, a two-year study conducted by Health Canada's National Radon Program. The study estimated that 7% of homes sampled in Canada and 8.2% of homes sampled in Ontario had radon concentrations above the Health Canada guideline of 200 Bq/m3. In Oxford County, there were 104 homes tested and twelve homes (approximately 11.5%) were above the guideline.

Where a home touches the ground, radon can get in anywhere it finds an opening including: cracks in the foundation, spaces around pipes, sump holes and floor drains, etc.
