It can get into any type of building and build up in your home. Breathing in Radon Gas for extended periods of time can potentially be hazardous to you and your family.


What to know

What you need to know about Radon


Radon is a colorless, odourless, radioactive gas that is found naturally in the environment.


Lung cancer remains the leading cause of cancer death for both men and women. Radon is the second leading cause of lung cancer only second to smoking! Radon can increase your chances of lung cancer if you are a smoker and according to the Canadian Lung Association Radon Gas exposure accounts for roughly 16 percent of lung cancer deaths in Canada.


Radon in living areas is measured in Becquerel's per cubic meter (Bq/m3). In 2006, Health Canada changed the acceptable standard annual radon concentration from 800 Bq/m3. Health Canada estimates that some parts of Canada have over 20 percent above the recommended levels.


Levels of Radon can differ from home to home it all depends on the construction and location.


Water from some deep wells may contain dissolved radon. This can lead to exposure by either drinking the water or inhaling the radon that has been released when that water is agitated (e.g. showering, washing clothes or cooking). While drinking water contains radon has not been shown to be harmful to health, the additional radon released into the air in water vapour may increase the inhalation hazard.
