Radon testing guides

Le radon est un gaz radioactif qui se forme dans le sol quand l’uranium se dégrade. Il entre par les fissures de la fondation et les joints des tuyaux. L’isolation et une maison étanche le retiennent à l’intérieur. Des années d’exposition causent le cancer du poumon, et ce gaz reste méconnu. Utilisez la recherche pour les mots que les gens cherchent : gaz radioactif, uranium, fondation, maison étanche, cancer du poumon, becquerels.

Radon in Edmonton: 1.4% in a 73-home sample, which is too small to skip the test

A low regional line on a short sample. It does not clear a closed house.

Radon in Calgary: 8.1% of 86 homes in the 2012 sample

Alberta’s two big cities did not match. Both samples are short.

25 oct. 2026

Radon in Brandon: 44.3% of homes in the 2012 health-region table

The clearest high result in Health Canada’s health-region table. It still is not your basement.

25 oct. 2026

Radon in Winnipeg: 12.1% of a small 2012 sample, not the Brandon number

People quote Manitoba and picture one city. The 2012 table splits Winnipeg and Brandon.

25 oct. 2026

Radon in Saskatoon: 7.9% in the 2012 sample, far under Regina

Same province, a much lower regional result. The house still needs its own test.

25 oct. 2026

Radon in Regina: 25.5% in the 2012 health region, and a later figure above half

Do not blend 25.5% and “over half” into one number. They are different studies. Test the house.

25 oct. 2026

Radon in Nunavut: zero of 78 homes in the 2012 survey, and what that leaves open

The lowest result in the country, on a limited sample, in a housing stock often raised off the ground.

25 oct. 2026

Radon in the Northwest Territories: 5.4% of 185 homes

A moderate territorial result. The 2012 table does not split out Yellowknife.

25 oct. 2026

Radon in the Yukon: 19.6% of homes, and a high share above 600

One of the four highest jurisdictions in the survey, with a thick tail of very high results.

25 oct. 2026

Radon in Prince Edward Island: the lowest provincial percentage in the 2012 survey

The lowest province in the Health Canada survey still had homes over the guideline.

25 oct. 2026

Radon in Newfoundland and Labrador: the west of the island tested higher than St. John’s

The 2012 Health Canada table splits the island. St. John’s does not speak for Corner Brook.

25 oct. 2026

Radon levels by province in Canada: the 2012 survey, not a postal-code map

Population-weighted and raw percentages above 200 Bq/m³ for every province and territory.
