What is Radon and Why It’s a Hidden Threat in Calgary
If you own or manage a commercial property in Calgary, you could be overlooking a serious indoor air quality risk: radon gas. Often undetected due to being odorless, colorless, and tasteless, radon exposure is a growing concern for Calgary businesses. Health Canada has consistently ranked Calgary among the Canadian cities with the highest indoor radon levels—posing risks not just to health, but also to regulatory compliance and workplace safety. Understanding the nature of radon and why it thrives in Calgary’s soil composition is the first step toward protecting your commercial space.

Understanding Radioactive Radon Gas
Radon is a radioactive gas released naturally from the breakdown of uranium in the ground. It permeates the soil and can effortlessly enter commercial buildings through foundation cracks, sump pits, or wall joints. Left unmonitored, this gas accumulates over time—invisibly increasing health risks while remaining undetectable without professional testing.
Why Calgary Has Above-Average Radon Levels
Calgary’s unique geology, particularly its glacial till soil and layering of shale and sandstone, creates a perfect environment for radon release. Cold seasons also exacerbate indoor concentrations, as commercial HVAC systems increase building airtightness, reducing natural ventilation. Health Canada studies underscore Calgary’s higher-than-average readings, with some commercial zones displaying radon levels more than double the national guideline of 200 Bq/m³.
How Radon Enters Buildings and Accumulates
In commercial structures, radon typically infiltrates from underlying soil and rock, moving into the building through foundational openings. HVAC systems can inadvertently draw more radon in due to pressure differentials. Once inside, radon gets trapped—especially in basements, mechanical rooms, or poorly ventilated areas—resulting in elevated exposure for occupants working in these zones.
Quick Fact: Radon is odorless and invisible—professional testing is the only reliable way to measure its presence in your commercial space.
Being aware of radon’s silent presence is step one. Next, learn how radon impacts your employees and business liability across Calgary’s commercial sector.
Radon Exposure Risks in Commercial and Office Settings
A modern business has legal, ethical, and health-related reasons to take radon seriously. Whether you’re a commercial landlord or facility manager in Calgary, ignoring radon levels in your office or retail space could expose tenants and employees to long-term health risks—and expose you to possible liability. Ensuring safe indoor air quality isn’t optional—it’s a legal and moral imperative that’s gaining traction with insurers, HR policies, and federal guidelines.
Health Effects of Long-Term Radon Exposure
Long-term exposure to elevated radon levels is directly linked to lung cancer. According to the World Health Organization (WHO), radon is the second leading cause of lung cancer after smoking. For non-smokers, it ranks as the top known cause. Even moderate exposure across working hours can create cumulative risk, especially in spaces where employees spend years.
Impact on Employees and Indoor Air Quality
Radon silently undermines efforts to maintain a healthy work environment. Unlike carbon monoxide or mold, radon gives no visual or sensory cues. Poor air quality directly correlates with reduced staff productivity, increased sick days, and lower tenant satisfaction—making radon detection a key element of corporate health and safety strategies.
Radon is the leading cause of lung cancer in non-smokers—and Calgary is in a high-risk zone. Start with a Calgary radon test to know your levels, then trust our experts for radon remediation in Calgary if needed. One call protects your home.
Legal and Insurance Implications for Businesses
Commercial building owners in Calgary could face serious liability if radon levels exceed Health Canada’s 200 Bq/m³ guideline and no action is taken. Should a worker develop a health issue linked to unsafe radon exposure, claims against the business or property manager could follow. In parallel, growing awareness around environmental safety means more insurers are beginning to request radon assessments during underwriting.
“Businesses may face liability claims if workplace radon levels are unsafe and unaddressed.”
Proactively managing your building’s radon levels not only safeguards health—it strengthens your legal and operational standing in Calgary’s competitive commercial environment.
How Commercial Radon Testing Works in Calgary
Your business can’t afford ambiguity when it comes to radon—precise, professional testing is essential. For Calgary property managers, the commercial radon testing process begins with selecting a certified expert and ends with clear, actionable data. Whether you’re concerned with baseline compliance or long-term diagnostics, understanding how the process works enables informed, timely decisions.
Choosing Certified C-NRPP Professionals
Commercial tests must be performed by C-NRPP (Canadian National Radon Proficiency Program) certified professionals to ensure acceptable methodology and documentation. Only certified technicians like those at Calgary Radon Detection are qualified to provide test results valid for regulatory or legal reference. They follow strict protocols to place detectors based on occupancy zones and HVAC system dynamics.
Pro Tip: Only C-NRPP certified professionals should be used for legally credible radon documentation in workplace settings.
Types of Radon Testing Devices for Commercial Use
Calgary’s commercial spaces often require a mix of digital and passive testing devices. Active monitors deliver real-time readouts over short testing periods (typically 48-96 hours), while long-term alpha track detectors gather data over 90+ days for more reliable seasonal averages. Device choice depends on intended use—routine surveillance, immediate diagnostics, or ongoing post-mitigation monitoring.
How Long Does a Commercial Radon Test Take?
Short-term assessments can be completed in as little as 2 to 5 days, while long-term tests require three months for seasonal accuracy. Businesses typically choose short-term tests for quick diagnostics, followed by long-term confirmation if elevated levels are discovered. During this period, environmental controls like ventilation and heating continue as usual to avoid false readings.
With the right experts and tools, testing your Calgary property provides peace of mind in just a few days—an easy decision that protects people, property, and compliance requirements.
Certified Radon Mitigation for Commercial Properties
Radon don’t wait—neither should you. If a radon test reveals elevated levels in your commercial space, it’s critical to act swiftly and correctly. Calgary Radon Detection delivers certified radon mitigation systems tailored to the structural and HVAC complexities of businesses across Calgary, AB. Whether you’re managing a storefront, high-rise, or office complex, we’re equipped to help you meet Health Canada’s radon limit of 200 Bq/m³—protecting workers and tenants while fulfilling provincial health and safety expectations.
Top mitigation strategies: Sub-slab depressurization & ventilation
The gold standard for most commercial buildings is active sub-slab depressurization. This system uses a fan and PVC piping to pull radon from beneath the foundation and vent it safely outdoors. In certain scenarios—especially where sub-slab access is restricted—mechanical ventilation is used to dilute radon concentrations with fresh air. Our expert team selects the optimal method based on building architecture, usage patterns, and HVAC design.
Commercial buildings often require custom mitigation designs due to HVAC and structural complexity.
Retrofit solutions for older Calgary buildings
Historic and older office buildings in Calgary often have crawlspaces, stone basements, or non-standard construction materials, making traditional radon mitigation challenging. Our C-NRPP-certified professionals specialize in retrofits, incorporating flexible ducting, perimeter suction systems, and crawlspace encapsulation to protect even the most architecturally unique properties.
What happens after mitigation? Post-install testing and compliance
Once installation is complete, we perform thorough post-mitigation testing to verify results. Documentation is provided for compliance with Alberta’s occupational health regulations. This proof of action safeguards commercial property managers against liability while demonstrating due diligence to stakeholders, building inspectors, and insurers.
