Where should I place the kit?
Place the detector in the lowest level of your home that is regularly occupied—typically a basement living area or ground-floor room. Keep it away from drafts, direct sunlight, high humidity areas, and exterior walls. The included placement guide has detailed diagrams to help you choose the best spot.
How long does the test take?
The detector must remain in place for a minimum of 91 days. You can leave it in place for up to 12 months if you prefer a longer sampling period. Long-term testing provides a more accurate annual average than short-term tests, which is why Health Canada recommends testing for at least 3 months during the heating season (October–April).
How do I return the kit?
After the testing period, seal the detector in the provided return envelope and take it to a Canada Post depot, post office, or authorized postal outlet. Do not use a street mailbox. The pre-paid tracked return label is included in your kit—no extra cost. You can track the return shipment using the tracking number on the label.
When will I get my results?
Results are typically delivered by email within approximately 2 weeks after the lab receives your detector. Your report includes your radon concentration in Bq/m³, how it compares to the Health Canada guideline of 200 Bq/m³, and clear Health Canada context for the result.
What if my result is above 200 Bq/m³?
If your result exceeds the Health Canada guideline of 200 Bq/m³, Health Canada recommends contacting a C-NRPP (Canadian National Radon Proficiency Program) certified radon mitigation professional. Your results email includes the Health Canada guideline and a link to the C-NRPP directory so you can find a certified professional in your area. According to Health Canada, mitigation systems can typically reduce radon levels by more than 80%.
Can I order multiple kits? Is there a discount?
Yes! We offer three quantity options: Lowest Level Home ($89 — 1 kit), Lowest Level + Main Level ($139 — 2 kits) — our most popular option — and Estate Sized Home Multiple Levels ($198 — 3 kits). Each kit includes the detector, lab analysis, pre-paid return shipping, and results delivered with Health Canada context. Use the quantity selector on the product page, then click Add to cart.
Do you ship to Quebec? / Livrez-vous au Québec?

Can I use this test for a Tarion warranty claim?
