Radon Gas In Canadian Homes

What is Radon Gas?

Radon is a colourless, odorless, radioactive gas that is present in our environment. It occurs when natural  uranium in soils and rocks break down. It is not man made. Some Canadian cities have higher levels of Radon than others according to a study done by the government in 1970.

Why Should You Be Concerned?

In the open air, radon gas dissipates and does not pose a health risk to humans. However, in confined spaces like basements radon can accumulate to  high levels over time and become a health hazard. Exposure to high levels of radon has been associated with an increased risk of lung cancer. Two recent independent scientific studies, one done in Europe, and one conducted in North America show that lung cancer can be correlated with levels of radon found in some homes. Radon is believed to be the second highest cause of lung cancer after cigarette smoking.

How Does it Get into Your House?

Radon gas will move through small crevaces in the soil and rock under a house’s foundation. It can seep into a home in a variety of ways, such as dirt floors, cracks in concrete, sumps, joints, jack posts and under the furnace base if the base is buried. Concrete-block walls are particularly conducive to radon leakage. There are other ways that radon can get inside a home as well.
