Worried about radon gas in your home?
Radon gas is both odorless and difficult to detect using our senses. The most reliable way to determine its presence is by conducting radon testing using DIY test kits or radon monitors.
Let’s discuss various radon testing methods in detail!
Before Testing Radon at Home
Radon is heavier than air and tends to accumulate in lower areas of buildings. It’s recommended to test for radon in the lowest level of your home, typically the basement. Remember to place the device 2 to 6 feet above the ground.
All the DIY testing kits and monitors mentioned here can be purchased at hardware stores, online, or through national radon offices.
Radon Testing Methods Comparison
Activated Charcoal Adsorption Kit
Activated charcoal adsorption is an easy way to determine if further radon inspection or mitigation is needed. This test works by using charcoal granules to absorb radon in the air, and then counting the number of radon using a scintillation detector. It takes 2 to 7 days to get the results from lab analysis.
While being simple and cost-effective, this test doesn’t give long-term radon measurements.
Radon Alpha Track Detector
As radon levels can fluctuate from season to season, it is also important to monitor the annual radon levels. In winter, when airflow is limited, radon levels can rapidly increase with closed windows and doors.
Alpha track detectors are recommended for long-term measurements, as they can be exposed for 3 to 12 months.
When air passes through the detector, radon particles cause tracks on a special plastic inside the container. These tracks are then counted using a microscope or optical reader to determine the radon concentration in the lab.
Radon Electric Monitors
If you don’t want to wait for a result from the lab, Smart Radon Detector can provide readings within 10 minutes to 1 hour. Some models even connect to mobile apps for easy access to data.
These monitors use an ionization chamber to sample the air and give a running average of the radon concentration. They are well-suited for real-time measurements of radon gas.
However, it’s worth noting that radon monitors are more pricey than DIY testing kits and accuracy can vary among different brands.
