November is Radon Gas Awareness Month
Radon is a radioactive gas that comes from the breakdown of uranium in soil, rock and water. Radon gas can enter your home or cottage where the house contacts the soil including cracks in foundation walls or floor slabs, gaps around service pipes and support posts, floor drains and sumps, and your water supply. Radon can be found in groundwater from private wells, too.
Note that Radon is colourless, odourless and tasteless.
Almost all homes have some Radon. The levels depend on many factors including the uranium content of the soil, the amount of contact of the home with the soil, the condition of the foundation, and occupant issues like the use of exhaust fans, windows and fireplaces.
Because there are so many factors, it is not possible to predict the Radon level in a home; the only way to know for sure is to test.
To learn more about Radon, and how to detect it in your home or cottage, visit Take Action on Radon.
