TESTING YOUR HOME FOR RADON

Radon, BC Real Estate blogs, new developments

Radon is a naturally occurring colourless, odourless and tasteless radioactive gas, formed when uranium in soil, rock and groundwater breaks down. It is not a problem outside because it is diluted when released into the air.

BUT Radon can seep into your home through any opening that is in contact with the ground. It can move through cracks in the foundation, gaps around pipes, floor drains, and window casements. This can happen in both new and old homes, and it’s different from building to building even in the same neighborhood.  Worse yet, Radon tends to accumulate in the lowest levels of a building, such as basements.  Long term exposure to high levels of Radon can cause lung cancer.

The limits for the concentration of radon is different around the world:

  • Health Canada’s limit guideline is 200 Bq/m3
  • The World Health Organization (WHO) recommends a limit of 100Bq/m3
  • United States has a limit of 148 Bq/m3

We do have a Radon tester and we will be happy to lend it to you for FREE to check the Radon levels in your home! Contact us

CONCENTRATION LEVELS IN BC

In B.C., the highest levels of Radon concentrations are found in the interior and northern regions.  A survey conducted by Health Canada concluded that homes within the Vancouver Coastal Health region generally had low concentrations.   However, some homes on the North Shore (North Vancouver, West Vancouver, the Sea to Sky Corridor) and the Sunshine Coast has been found to slightly exceed the Canadian guidelines.

You can purchase a Radon test kit at some hardware stores or online from several organizations that are working to reduce the concentration levels.  You can also hire a certified professional to perform a test for you.

If the level is above 200 Bq/m3, you should work certified professional to lower the levels in your home. Even if the levels are below 200 Bq/m3, you may still want to try to get them lower.

RADON IN HOMES IN BC

BC Financial Services Authority now considers radon to be a latent defect. When you are selling your home you have to fill in a Property Disclosure Statement which now includes questions like:

  • Has the Unit/Common property/Lands being tested for Radon?
  • What was the most recent level detected?
  • Is there a Radon mitigation system in your home?

If you planning to buy a home, you should consider purchasing in an area where the likelihood of high concentration of Radon is low, or testing the home  prior to firming up the purchase.

Awareness of Radon has historically been very low.   However, in the past 10 years, more evidence of communities with elevated levels has been found, and it appears that the provincial government and municipalities are starting taking it more seriously.

Radon can accumulate in schools & work places and any other indoor environment. In winter 2017/2018 VCH tested public schools on the North Shore, Sea to Sky, Sunshine Coast, Powell River and Central Coast. Download the Results Report.

The BC Centre for Disease Control has released an Interactive Map. Find out the levels in your area!
