What is radon gas and where does it come from?
Radon is a radioactive gas formed from the natural breakdown of uranium in soil, rock, and water. It is colourless, odourless, and tasteless, making it virtually undetectable without specialized equipment. As radon rises from the ground, it can seep through foundation cracks, pipes, or sump pumps—accumulating in enclosed structures. Commercial buildings with underground levels or aging ventilation systems are particularly susceptible.
Why radon levels matter in Calgary buildings
Due to Calgary’s northern climate, commercial structures often operate in closed-air mode for months during winter. HVAC systems recirculate indoor air to conserve energy, but this also traps radon inside. Without proper monitoring, radon concentrations can spike seasonally, often surpassing Health Canada’s radon guideline limit of 200 Bq/m³.
Radon is a radioactive gas that naturally forms in the ground and accumulates indoors — especially in sealed, low-ventilation areas.
Understanding radon’s link to commercial air quality standards
Maintaining indoor environmental quality (IEQ) in workplaces involves more than just balancing temperature and humidity. Radon falls under air quality assessments and is critical for compliance with indoor pollutant exposure guidelines. Regular commercial radon testing ensures you’re aligning with modern air quality expectations laid out by Health Canada and Alberta OHS regulations.
Local radon testing services like Calgary Radon Detection help verify safe working conditions—on your schedule and with certified precision.

Do you know what your employees are breathing for 8+ hours a day? Radon gas isn’t just a residential issue — commercial buildings in Calgary face rising concerns over long-term exposure. Proactive testing is essential to protect health and meet workplace safety mandates.
How radon causes lung cancer — even in non-smokers
Radon gas decays into radioactive particles called polonium isotopes. When inhaled, these particles can damage the lining of the lungs. Over time, this cellular radiation damage leads to an increased risk of lung cancer—even in individuals who have never smoked. Studies from Health Canada show a direct link between elevated radon levels and occupational health risks.
Health Canada guidelines and what exposures are considered dangerous
Health Canada recommends corrective action if radon levels exceed 200 becquerels per cubic meter (Bq/m³). Yet properties testing over 300 Bq/m³ are not uncommon—especially in older or poorly ventilated buildings. The risk grows with prolonged exposure, which is why commercial radon testing with calibrated digital radon monitors is strongly encouraged for all business properties in Calgary.
According to Health Canada, radon is the second-leading cause of lung cancer in the country.
The unseen risk to employees spending 8+ hours in commercial buildings
Employees stationed in high-radon environments face significant health burdens due to cumulative exposure. A full-time employee may unknowingly inhale radon-contaminated air for thousands of hours annually. Unlike more obvious safety threats like carbon monoxide leaks, radon works in silence—often revealing its damage only decades later.
Employees in high-radon workplaces can be exposed for thousands of hours annually — dramatically increasing health risks over time.

Regulations, Insurance, and Radon Liability for Calgary Businesses
A compliance specialist verifies commercial air quality and radon safety standards in a Calgary office environment.
Compliance isn’t optional when it comes to hazardous indoor air pollutants like radon—especially in professional commercial environments. Across Calgary, OHS regulations and insurance considerations are tightening around radon prevention. Owning or managing a property requires active awareness and mitigation planning.
Alberta OHS laws and indoor air quality requirements
The Alberta Occupational Health and Safety Code mandates that employers ensure indoor environments are free from known air contaminants. Radon testing falls squarely under this mandate. Section 4 of the code addresses exposure limits and signals legal obligations for detection and reduction of airborne carcinogens like radon before employee health is compromised.
Alberta’s Occupational Health and Safety Code requires employers to ensure an indoor environment free from known air contaminants like radon.
Can radon levels affect commercial insurance or liability?
Yes — increasingly so. Commercial insurance underwriters in Calgary are beginning to incorporate indoor environmental quality data into property risk profiles. Excessive radon concentrations may result in higher premiums, denied coverage for health-related claims, or increased general liability if tenant or employee health is impacted. Long-term liability can even affect resale value or leasing viability for commercial properties.
Reduced radon levels can potentially lead to lower insurance premiums or reduced liability exposure according to local insurance agents.
Workplace safety compliance for long-term employee health
As part of environmental due diligence, many Calgary businesses now factor radon testing into annual workplace health audits. Protecting employee health is not just a moral obligation—it’s a smart HR strategy. Certified testing also demonstrates proactive leadership to regulators, insurers, and employees alike. Calgary Radon Detection works with property managers to deliver professional reports tailored for compliance documentation.

How Radon Testing and Mitigation Works in Commercial Buildings
A properly designed radon mitigation plan for your Calgary commercial space begins with accurate, certified testing. If you’re a property manager or business owner looking to uncomplicate radon compliance, understanding the professional processes involved is key. At Calgary Radon Detection, we demystify radon testing and remediation with efficient steps and high-performing systems tailored for large-scale spaces.
Step-by-step breakdown of testing using long-term kits and CRM devices
Professional radon testing typically involves the deployment of long-term alpha track detectors or Continuous Radon Monitors (CRMs), ideally over a 90+ day period to capture seasonal variations. C-NRPP-certified technicians strategically place monitors in frequently occupied zones — such as offices, conference rooms, or employee lounges — ensuring accurate readings aligned with Health Canada guidelines.
C-NRPP-certified professionals typically perform testing using long-term alpha track detectors or continuous radon monitors over 90+ days.
Common commercial radon mitigation systems like sub-slab depressurization
If elevated radon levels are detected, mitigation solutions vary based on your building layout. The most common and effective method is active sub-slab depressurization (ASD), which vents radon-laden soil gases before they enter the structure. In commercial retrofits, this may involve multiple suction points or fan-assisted piping routed through mechanical zones to maintain aesthetics without compromising performance.
Other methods include heat recovery ventilation (HRV) systems or fully integrated air-exchange solutions for larger complexes such as schools or warehouses. Calgary Radon Detection customizes each mitigation approach to match the architectural and air-pressure challenges specific to commercial Calgary properties.
Timelines: when and how often to test your commercial space
Initial testing should occur during peak occupancy — typically winter months — when buildings are most sealed off. Retesting is recommended every five years or after major structural changes, HVAC retrofits, or renovations. For high-occupancy spaces like medical clinics or daycares, annual testing may be warranted under internal safety protocols or insurance compliance guidelines.
Stay compliant and protect your space — schedule a certified radon test before peak season hits.
