What is Radon?
Radon is the #1 cause of lung cancer in non-smokers.
You can’t see it, smell it or taste it, but this naturally occurring radioactive gas can leak into your home from soil, rock and groundwater. It’s also the leading cause of lung cancer in non-smokers.
Radon gas gets into homes by entering the basement through cracks in the foundation, drains and spaces around pipes. Radon can pass through tiny cracks that are invisible to the eye. Once inside, radon gas levels can accumulate.
According to a survey of homes conducted by Health Canada in 2009:
- 15% of homes tested across Wellington-Dufferin-Guelph tested above the recommended guideline for radon
- 18% of homes tested in Guelph tested above the recommended guideline for radon
High levels of radon present a health risk: radon is the leading cause of lung cancer in non-smokers. And the risks of developing lung cancer from radon are greater for smokers and those exposed to second-hand smoke. The only way to know the level of radon in your home is to test for it.
Testing your home for radon is easy and inexpensive. Health Canada recommends using an approved long-term radon detector for at least three months. The best time to test is between October and March, when windows and doors are usually closed. If the radon level in your home is high, there are steps that you can take to lower it.
