Radon guides the test, the report, and when to mitigate
An address does not give a radon level. The gas comes from the soil, it has no smell and no colour, and two houses side by side can be very far apart. This guide sorts the blog posts by the decision you have to make.
Understand, then measure
What radon is, the 200 Bq/m³ guideline and how to do the test cover the basics. The room and the season are in where to place the detector and when to test in Quebec.
Read the result
Reading Bq/m³ and, if the number is above Health Canada’s line, what follows above 200. A system already in place is checked again: how often to retest.
Correct it
How a system works, what changes the price and why an air exchanger does not replace suction under the slab.

The map of Quebec shows the sectors. It does not replace the detector in the room where you live.
Canada, province by province
The percentages from the Health Canada survey (winters 2009–2011) are gathered in radon by province. Pages that take one place out of that table: Gaspésie, Manitoba, Saskatchewan, Ontario, New Brunswick, Yukon. In English: radon levels by province.
Questions, one by one
Placement, health, guidelines, wells, cottages, condos and breakdowns: all the questions.
The 4-day test gives a first reading. The 91-day test covers the three-month minimum Health Canada asks for. Both are $59 before tax: shipping, return and the laboratory are included, taxes extra. The PDF report is sent within 2 business days after the laboratory receives the detector.
Above 200 Bq/m³, mitigation is confirmed with a quote. Gaz Radon is C-NRPP certified for measurement and mitigation.
