Choosing the Right Radon Monitor or System When selecting a radon monitor or mitigation system for your home, there are a few important factors to consider. First, decide whether you prefer a short-term test or a continuous monitoring system. Short-term monitors are generally affordable and simple to set up. However, they must be used under specific conditions to ensure accurate readings. Some models also require shipping to a laboratory for analysis once the test period is complete. Long-term monitors, or continuous radon devices, track radon concentrations over extended periods and provide ongoing data. The accuracy and precision of these devices vary depending on their design and sensitivity. A high-quality monitor will record multiple readings per hour rather than relying solely on a rolling average. Monitoring radon levels is especially important during the winter months, when windows and doors remain closed and heating systems are in use. These “closed conditions” provide a more accurate picture of your true radon exposure. It’s also advisable to test your home after major renovations or changes to your HVAC system, as these can affect air pressure and radon entry points. Before beginning any mitigation work, it’s best to consult with a C-NRPP–certified radon professional who can explain the mitigation process and help determine the best solution for your property. Remember, radon mitigation reduces levels significantly, but it is not possible to remove radon entirely. The goal is to bring concentrations down to a level that is safe and compliant with Health Canada’s guidelines.
