RADON TESTING IN REGINA.
91-day Health Canada protocol. Performed by a C-NRPP certified specialist.
Overview
Radon is a radioactive gas that comes from the breakdown of uranium in soil and rock. It moves through cracks in the foundation, around utility penetrations, and through the slab itself, and it accumulates in the lowest enclosed level of a home. Regina is, by Health Canada's own survey data, the highest-radon city in Canada — about half of homes here test above the 200 Bq/m³ action level. The number does not get smaller by being ignored.
Wind Rose runs Health Canada–protocol long-term radon testing. The test is a 91-day continuous measurement of the air in the lowest occupied level of the home, deployed during the closed-house season (the months when windows stay shut). At the end of the test period the device is retrieved, the data is reviewed, and a written report is issued — including the average concentration in Bq/m³ and a recommendation for whether mitigation is required.
Short-term tests (2–7 days) exist and have their place — typically real-estate transactions on a closing timeline — but the long-term protocol is what Health Canada points to for a real read on a home's actual radon exposure. Wind Rose runs both. The 91-day report is the one most homeowners need.
C-NRPP CERTIFIED. RED SEAL TRADE.
C-NRPP is the credential Health Canada points to for compliant radon work in Canada. Wind Rose holds it. Most Regina mechanical contractors do not. The Red Seal trade card means the same hands that read your radon test can also size and install the mitigation system, run the gas line for the boiler in the same basement, and sign off on the plumbing — without a subcontract.
C-NRPP is the certification required for Health Canada–compliant radon testing. Without it, a test report is not credentialed work.
The Process
Consultation
Confirm the home's lowest occupied level, the closed-house season window, and whether a long-term or short-term test fits the situation.
Same-day phone scheduling
Deployment
Place a calibrated continuous radon monitor in the correct location per protocol. Test runs untouched.
91-day measurement window
Retrieval & Report
Retrieve the device, review the data, and issue a written report with the average Bq/m³ reading and a mitigation recommendation if the result exceeds the Health Canada guideline.
Written Bq/m³ report
Next Steps
If mitigation is indicated, the same Red Seal trade who ran the test can design and install the mitigation system end-to-end. No referral, no second contractor.

Frequently asked
How long does a Health Canada radon test take?
The Health Canada protocol calls for a long-term test of at least 91 days during the closed-house season — the months when windows stay shut and the air in the home reaches its real average exposure. Short-term tests (2–7 days) exist for time-sensitive situations like real-estate transactions, but the 91-day result is the one Health Canada actually references for risk decisions.
How much does radon testing cost in Regina?
Wind Rose's radon testing starts at $325 for a long-term Health Canada–protocol test, including device deployment, retrieval, and a written report in Bq/m³ with mitigation recommendation. Short-term tests on a real-estate timeline are priced separately.
What is a safe radon level?
Health Canada's action level for residential indoor radon is 200 Bq/m³ (Becquerel per cubic meter) averaged over a long-term measurement. Above that, mitigation is recommended. The World Health Organization recommends a lower threshold of 100 Bq/m³, which some homeowners choose to use as their own action level.
Why is Regina especially high for radon?
Regina sits on uranium-rich prairie soil with a clay-heavy water table that tends to trap gas under the slab. Health Canada survey data has repeatedly found about 50% of Regina homes test above the 200 Bq/m³ action level — compared to roughly 16% across Saskatchewan and about 7% nationally. Regina, Saskatchewan is the radon capital of Canada.
Do I need a long-term test if I'm selling my home?
Real-estate transactions usually move on a timeline that does not allow a 91-day test. Short-term radon tests (2–7 days) are designed for that situation and Wind Rose runs them. A long-term test is still the right call once the new owner takes possession — the short-term reading is a snapshot, not an average.
Can you test a commercial building?
Yes. Commercial radon testing follows a different protocol from residential, but the C-NRPP credential covers both. Wind Rose runs commercial radon assessments for tenant-improvement projects, occupied-building surveys, and pre-purchase commercial inspections.
