You can now borrow a Radon Detector from the Library!

Radon is a naturally occurring radioactive gas that is formed by the breakdown of uranium in soil, rock and water. The only way to detect radon in your home is through long-term testing using a radon monitor. Health Canada has determined that the current guideline for radon in your home or workplace is 200 becquerels per cubic metre (200 Bq/m3).

Radon levels in homes can vary significantly over time. In fact, it is not uncommon to see radon levels change by a factor of 2 to 3 over a 1-day period, and variations from season to season can be even larger. If you detect a high level of radon in your home while using our short-loan detectors, Health Canada recommends that you conduct a longer test for at least three months by either purchasing your own detector or by hiring a professional. More information can be found by visiting Take Action on Radon.

How can I Reduce the Amount of Radon in my Home?

If your radon test result is above the guideline of 200 Bq/m3 you should hire a mitigation professional certified under the Canadian National Radon Proficiency Program. To learn more, visit or call 1-855-722-6777

Health Canada recommendation for remedial action:
  1. Remediate within 2 years: Results between 200 and 600 Bq/m3, Health Canada recommends taking steps to reduce the radon level within 2 years.
  2. Remediate within 1 year: Results greater than 600 Bq/m3, Health Canada recommends taking steps to reduce the level within 1 year.

While the health risk from radon exposure below the Canadian Guideline is small, there is no safe level of radon. It is the choice of each homeowner to decide what level of radon exposure they are willing to accept.
