Is there Radon in Ottawa

Radon is big news due to the dangerous effects of having it in your home. Radon is hazardous, especially at high levels, and a known carcinogen. You may have read that radon gas problems are spread throughout Canada but tend to be more concentrated in some geographical regions.

So, does Ottawa have a radon gas problem or not? And if so, what areas is it found?

What Levels Of Radon Are Dangerous?

Radon, which can cause lung cancer, is present in many houses and other buildings in varying amounts. The higher the concentration, the more dangerous it is. Health Canada rates the following 3 levels according to their degree of danger and the urgency of taking action.

  • Less than 200 Bq/m3: acceptable level, no follow-up action necessary
  • 200 to 600 Bq/m3: moderately dangerous, action required within the next 2 years
  • 600 Bq/m3 or above: hazardous, mitigation required within the next years

NOTE: Bq/m3 stands for becquerels per cubic metre, the typical Canadian measurement for describing radon levels.

Is Radon A Problem In Ottawa?

Yes, radon is definitely a problem in Ottawa and the National Capital Region, as it is across the country. As a naturally mineral-rich land, Canada has the largest reserves of uranium anywhere on the planet. As this uranium decays (breaks down), it produces radon gas. Although the air will dilute radon gas to harmless levels outdoors, this gas will concentrate inside your home, most frequently in enclosed places on the lowest floor.

What Areas In Ottawa Have High Levels Of Radon?

Areas of Ottawa tend to have a higher incidence of dangerous radon gas levels.  Some main parts of Ottawa that have higher levels are:

  • Kanata
  • Stittsville
  • Bells Corners
  • Carleton Place
  • Barrhaven
  • Centrepointe
  • Bel Air Heights
  • The Glebe

Are Some Types Of Homes More Exposed To Radon?

The type, style or even the dollar value of your home will not make it more or less vulnerable to radon. Funnily enough, two similar houses on the same block in Ottawa each could have very different radon levels.

How does your home get exposed to radon:

  • the presence of uranium in the rock and soil under your foundation PLUS
  • openings that allow radon gas inside, such as a sump pit, foundation or basement cracks, an unfinished crawl space, construction joints, plumbing openings, and the like.

Should I Buy A Home That Has Radon?

Imagine you’ve found your dream home in Ottawa. It offers the features you most want… and then you find out it has radon. Should you buy the house, radon and all, or just walk away?

Don’t give up on your dream. First of all, find out what it means that the house for sale “has radon”? Have the sellers had it professionally radon tested, with either a long term radon testing or short term radon test? If so, how high were the results?

Second, bear in mind that even dangerous amounts of radon in a home can be effectively reduced with expert mitigation. Active Soil Depressurization (ASD) is a non-invasive, reasonably priced radon mitigation system that will make your home secure and healthy.
