This November, as part of Radon Action Month, Health Canada is encouraging Canadians to test their homes for radon. Radon is the number one cause of lung cancer in non-smokers, leading to the deaths of more than 3,200 Canadians each year.

Radon is a radioactive gas naturally produced by the breakdown of uranium in the ground. It can easily enter homes undetected through cracks and gaps in the floors and walls that are in contact with the ground. You can’t see it, smell it or taste it. All homes and buildings have some level of radon. The only question is how much and the only way to know is to test.

Find out what you can do on the Take Action on Radon web page, and don’t forget that some local libraries also have lending programs for radon detectors.
