The Silent Threat: Why Continuous Radon Monitoring Matters

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It can enter buildings through foundation cracks, floor joints, and service penetrations. Because it is odourless, colourless, and invisible, it often goes undetected until it becomes a significant health concern. According to Health Canada, radon exposure is the leading cause of lung cancer among non-smokers and contributes to more than 3,000 deaths in Canada each year. While every building has some level of radon, sustained exposure to elevated concentrations is the concern, and that risk can only be managed through consistent measurement.

Fluctuating Levels Require Continuous Monitoring

Radon concentrations are constantly fluctuating. They vary with temperature, humidity, ventilation rates, and building pressure. Traditional short-term tests, which capture data over just a few days, often fail to reflect real exposure levels.

By contrast, continuous monitoring delivers ongoing data trends that reveal daily and seasonal fluctuations. These insights enable building owners and property managers to:

• Identify and confirm sources of radon intrusion.
• Assess the effectiveness of mitigation systems in real time.
• Maintain compliance with safety guidelines and occupational exposure limits.
• Provide verifiable documentation of air quality conditions

A Radon Monitoring Solution

Polygon Climate Control’s radon detector can integrate seamlessly with other Exactaire sensors to deliver precise, real-time visibility into indoor air conditions.

Key capabilities include:

• Continuous, real-time data collection: Capture hourly readings for accurate trend analysis and long-term evaluation.
• Automated alerts: Configurable thresholds trigger notifications when radon levels exceed safe limits.
• Cloud-based platform: Access live readings and historical data from any device through Polygon Climate Control’s secure portal.
• Comprehensive data integration: Merge radon measurements with temperature, humidity, dew point, and differential pressure data to understand overall indoor air quality.
• Simple deployment: Compact sensors and wireless connectivity make installation and scalability straightforward for both new and existing buildings.
