Calgary Commercial Radon Testing: A 2025 Guide for Business Owners

Radon is emerging as one of Calgary businesses' top health and safety concerns in 2025. With growing evidence of its serious health risks, commercial property owners can no longer ignore this invisible danger. Radon is a proven carcinogen. When concentrations rise indoors, particularly in sealed, at-grade environments, it poses a threat not only to building owners but also to employees, customers, and tenants. 

Why Businesses Should Prioritize Radon Testing & Mitigation 

The demand for radon safety is rising in Calgary, with Health Canada data and local surveys showing that many homes and commercial buildings exceed recommended exposure levels. Alberta’s distinct geology—rich in naturally occurring uranium—contributes to elevated indoor radon concentrations. For businesses, proactive testing and mitigation are not only vital for protecting employee health but also for reducing long-term liability and ensuring regulatory compliance.

What You Should Know about Radon Gas in Commercial Buildings

Sealed, airtight commercial spaces—especially those with basements or underground parking—are particularly susceptible to radon infiltration. The gas can enter through cracks in concrete slabs, floor drains, utility penetrations, and construction joints. Without proper testing, radon can accumulate over time to hazardous levels, posing significant health risks to occupants.

Occupational Hazard: Radon Exposure in the Workplace

Employees working in offices, workshops, retail spaces, and warehouses may be exposed to elevated radon levels for extended periods—often eight hours a day or more. Prolonged exposure significantly increases the risk of lung cancer, even among non-smokers. Beyond the health implications, awareness of radon exposure can affect employee morale and productivity, as staff may feel unsafe or concerned about their work environment.

What Employers Need to Know About the Health Risks

Health Canada recognizes radon as the leading cause of lung cancer among non-smokers. Even moderate, long-term exposure can pose serious health risks, making radon awareness and mitigation a critical responsibility for Calgary employers.

Home Radon levels in Calgary: 

Recent assessments indicate that several Calgary neighborhoods—particularly in the Northwest and Southeast—can have elevated Radon Levels. These areas are situated on uranium-rich soils and contain many older buildings with inadequate ventilation, making them especially high-risk. Radon testing is essential for both residential and commercial properties to ensure occupant safety and regulatory compliance.

Work Safety and Radon: Legislative and Ethical Strategies

Canadian employers are legally required to maintain safe work environments, which includes managing environmental hazards like Radon. Ethical and proactive leadership begins with regular testing and acting on results to protect employees and the public.

Key Benefits of Commercial Radon Testing for Businesses in Calgary

Commercial radon testing delivers both immediate and long-term benefits. It enhances indoor air quality, supports employee health, and can help reduce absenteeism. Conducting testing also demonstrates a strong commitment to safety, transparency, and regulatory compliance—strengthening your company’s reputation with clients, regulators, and the public. Early detection and mitigation minimize the risk of costly health claims, legal liabilities, or expensive retrofits in the future.

How to Choose A Professional Commercial Radon Testing Service in Calgary

When selecting a radon testing service, look for a certified professional with credentials from the Canadian National Radon Proficiency Program (C-NRPP) and proven experience in commercial settings. Commercial buildings have unique ventilation systems and structural complexities that require specialized expertise. While long-term testing provides the most accurate results, short-term testing can offer valuable preliminary insights.

Protecting Yourself From Workplace Radon Exposure

Start by consulting a certified radon professional to assess your building. After mitigation, always conduct follow-up testing to verify that radon levels have been successfully reduced.

Conclusion

In 2025, health and safety standards for commercial spaces are more stringent than ever. For Calgary businesses, radon testing is no longer just a recommendation—it’s a necessity. With growing public awareness and evolving regulations, proactive testing and mitigation are the smartest ways to protect your employees, safeguard your business, and uphold your reputation.
