November is National Radon Action Month and Health Canada is encouraging Canadians to test their homes for radon.


What is radon?


Radon is a radioactive gas that is produced naturally by the breakdown of uranium in the ground. Since radon can’t be seen, smelled, or tasted, it can get into your home undetected. In outdoor air, radon is diluted and therefore not a concern. But in confined spaces like your house, radon can build up to high levels and become a health risk.

Radon can enter your home any place where the house touches the soil and there is an opening.


  • Radon is the second leading cause of lung cancer after smoking
  • Every home has some level of radon.
  • Fall is the best time of year to test your home for radon.
