Start with the question you have right now
Test for Radon
Learn how long to test, where to place a device, and the difference between short-term screening and a long-term measurement.
Understand Your Result
Health Canada’s radon guideline is based on a long-term average. See what a result above 200 Bq/m³ means and how quickly action is recommended.
Reduce Radon
Learn how professional mitigation works, what affects the price, and what to ask before hiring a radon professional.
What does 200 Bq/m³ mean?
The Canadian radon guideline is 200 becquerels per cubic metre (Bq/m³). Health Canada recommends corrective action when the average annual radon level in a normally occupied area is above that guideline, and recommends acting sooner as concentrations increase.
For a decision about mitigation, Health Canada’s current residential measurement guidance uses a minimum 91-day long-term measurement. A short-term reading can be useful as a screening signal, but it is not the same thing as the long-term average used for the Canadian guideline.

Radon testing in Winnipeg
Winnipeg Public Library offers radon screening kits during the colder part of the year. The City says the kits are available from November 1 through April 30 and are intended for short-term screening. The City also cautions that these screening devices do not replace Health Canada’s recommended long-term testing.
Already have a reading?
If you have a test result and are unsure what it means, start with the result guide. If you are ready to speak with someone about mitigation, you can request local help.
Radon can be reduced
Health Canada identifies active soil or sub-slab depressurization as the most common professional radon-reduction approach. A fan and pipe system draws radon-containing soil gas from beneath the home and exhausts it outdoors before it enters the living space.

For testing and mitigation, Health Canada recommends using appropriately qualified professionals, including C-NRPP-certified radon professionals.
