WHAT IS RADON?
Radon is a naturally occurring radioactive gas that is released by the breakdown of uranium in the Earth's crust. It is found everywhere on the surface of the planet.
Whether your home is new or old, radon can find its way into it. Since radon is odourless, colourless and tasteless, the only way to detect it is to use a radon detector.
In Canada, it is estimated that 16% of deaths caused by lung cancer are associated with radon exposure.

WHY MEASURE RADON IN YOUR HOME?
Although radon dissipates quickly outside, it can accumulate in our home, reaching high concentrations and creating long-term health problems. In Québec, approximately 10% of homes are said to exceed the radon concentration recommended by Health Canada.In Canada, it is estimated that 16% of deaths caused by lung cancer are associated with radon exposure.
More information on this gas may be found in the Quebec Lung Association's brochure (Radon: Are you at risk?) (see download section).
It should be noted that the presence of radon in a neighbor's home does not necessarily mean that it is present elsewhere. Concentrations can vary considerably from one home to another, even if they are close to each other.
Several factors influence radon levels:
- the composition of the soil under the house;
- the condition and waterproofing of the foundation;
- the configuration of the basement;
- the ventilation system;
- atmospheric conditions.
The only reliable way to know if a home is affected is to conduct a screening test. Screening kits are available online, at some hardware stores, or from a certified professional.
