Radon

What Is Radon & How Is Your Health at Risk?

Radon is a colourless, odourless, and radioactive gas that is naturally occurring caused by the breakdown of uranium in soil, and you can’t see, smell, or taste it. Outside, radon gas disperses into fresh air, and is harmless. Though naturally occurring outdoors, radon can be a threat to your health indoors, where it can accumulate to high levels when it enters through pipes, drains, and foundation cracks.

The Ontario Lung Association has shown that smokers who are exposed to high levels of radon have a 1 in 3 chance of developing lung cancer, compared to a 1 in 10 chance for smokers not exposed to radon. Radon is measured in Becquerels per cubic meter (Bq/m 3). Health Canada recommends that homes should not exceed 200 Bq/m3.

Radon Testing

The only way to know whether your home has radon is to test it. Fortunately, testing your indoor environments for radon is easy and inexpensive! 

Health Canada recommends testing your environment for 90 days to 1 year, using a long-term detector certified by the Canadian National Radon Proficiency Program. 

Detectors cost approximately $50, and can be purchased at EcoSuperior, local hardware stores, or rented out by your local library for free.
