Is Radon Monitoring Necessary? What Homeowners Should Know
Radon is an invisible, odorless gas that can seep into homes from the ground below. Because it’s undetectable without proper equipment and can contribute to serious health issues (it’s the second leading cause of lung cancer), radon is a concern for many homeowners. One question we often get asked is whether it’s enough to do a one-time radon test — or if it’s worth investing in a continuous radon monitor.
The truth is that radon levels can fluctuate daily, weekly, and seasonally. A single test may not always capture the full picture. That’s where ongoing monitoring comes in.
What Is a Radon Detector?
A radon detector is a device designed to measure the level of radon gas inside your home. There are different types, ranging from basic short-term kits to advanced digital monitors.
Short-term radon test kits measure levels for a few days or weeks. They’re inexpensive and accessible but only give a snapshot of your home’s air quality.
Electronic and digital radon detectors offer a more accurate and longer-term view of radon levels. Many of these devices include displays, data logs, or even phone apps, allowing homeowners to track changes easily.
No matter which you choose, the goal is the same: protecting your household from radon exposure.
Continuous Radon Detector vs. Short-Term Tests
Short-term test kits are a good starting point for detecting radon. They’re useful for identifying immediate risks and are often recommended when buying or selling a home. However, they have limitations. A test conducted in the winter might show elevated levels, while the same test in summer could read much lower.
A continuous radon monitor fills that gap. These devices track levels around the clock, providing real-time data and alerts if radon concentrations rise above safe levels. Instead of relying on a one-time reading, you gain a clear picture of how radon behaves in your home year-round. This ongoing awareness is especially valuable in areas known for fluctuating radon levels.
How Does a Continuous Radon Monitor Work?
Continuous radon monitoring devices use sensitive electronic radon gas sensors to measure levels in your home’s air. The data is updated regularly, often hourly, and displayed on a digital screen or sent directly to your smartphone. Some models act as a radon alarm, alerting you immediately when levels exceed recommended thresholds.
By offering real-time visibility, these devices empower homeowners to act quickly if radon levels rise, and they help confirm whether a mitigation system is effectively reducing radon exposure.
Why Ongoing Monitoring is Important
Unlike other household risks, radon levels are not fixed. They can fluctuate due to:
Seasonal shifts in air pressure and ventilation
Weather conditions such as storms or heavy rainfall
Changes in how a home is used (open windows, basement renovations, HVAC adjustments)
Because of these fluctuations, relying on a single test can create a false sense of security. A long-term radon monitor ensures that you’re always aware of your home’s air quality, helping you make informed decisions about when to take action.
