The Silent Threat: Why Continuous Radon Monitoring Matters

Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. It seeps into buildings through foundation cracks, floor joints, and service penetrations. Because it’s odorless, colorless, and invisible, it often goes undetected until it poses a significant health risk. According to the U.S. Environmental Protection Agency (EPA), radon exposure is the second leading cause of lung cancer in the United States, responsible for more than 20,000 deaths annually. 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’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’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.
