Keeping your home safe involves more than just locking doors and windows; it also means being aware of invisible threats like radon gas. Radon is a naturally occurring radioactive gas that can build up indoors and is the second leading cause of lung cancer in the United States. Radon testing is the only way to know your home’s radon level, so knowing the different types of radon tests is important.
Testing for radon is the first step in protecting your family from exposure.
In this article, we’ll explore the different types of radon tests available, from short-term and long-term kits to advanced continuous monitoring systems like our proprietary Radon Sentinel™ Radon Measurement System
What is Radon Testing?
Radon testing measures the concentration of radon gas in a home or building. It uses detectors or monitors placed in specific locations for a set period of time. These tools show whether radon levels exceed safety guidelines. Results help homeowners take the right steps to reduce risk and protect indoor air quality.
Regular radon testing helps track changes over time. It also supports a safer living environment for you and your family.
What are the Different Types of Radon Tests?
There are several types of radon testing devices. Each serves a different purpose and offers its own benefits. Learning about these options helps you choose the best approach for your home.
The most common include:
- Short-Term Test Kits: These are typically used for initial screening and provide results quickly, usually within 2 to 7 days. They include activated charcoal canisters, electret ion chambers, and alpha track detectors.
- Long-Term Test Kits: These devices, such as alpha track detectors and electret ion chambers, remain in the home for an extended period, typically 90 days to a year, offering a more full picture of the average radon level in the home over time.
- Continuous Radon Monitors (CRMs): These electronic devices continuously measure radon levels over time. Depending on its calibration, a CRM can record a radon level every hour for 48 hours and then provides the average of those levels to determine your result. Our proprietary Radon Sentinel™ Radon Measurement System, a leading product in this category offered by Protect Environmental, provides active radon monitoring and detailed reporting, making it a preferred choice for both residential and commercial radon risk analysis.

How Do The Different Radon Tests Work?
Each type of radon test has its own way of detecting and measuring radon levels.
- Short-Term Test Kits: Activated charcoal canisters absorb radon gas. A laboratory analyzes the canister to determine radon concentration. Electret ion chambers and alpha track detectors also capture radon particles for lab review.
- Long-Term Test Kits: These tests work in a similar way but remain in place for a longer period. This produces an average level that accounts for radon changes due to weather and seasonality.
- Continuous Radon Monitors (CRMs): A CRM uses sensitive electronic components to read radon levels frequently. It records and stores data for quick reporting. Only certified radon professionals conduct CRM testing. Contact your home inspector or work with our Protect Environmental team to schedule CRM radon test for your home.
How Long Does It Take to Get the Results?
The time it takes to get radon test results depends on the type of test you use. Some tests provide results within a few days, making them ideal for initial screenings, while others take longer but offer a more detailed picture of radon levels over time.
- Short-Term Test Kits: Results are typically available within a week after the testing period ends (depending on shipping times) as the kit is mailed to a laboratory for analysis.
- Long-Term Test Kits: These require 90 days to a year for data collection, with results available shortly after the testing period depending on shipping times and lab analysis turnaround times.
- Continuous Radon Monitors (CRMs): Because radon test results are electronically recorded, reports with your test results can be provided within just a few days depending on your provider.
Which Type of Radon Testing Is Better to Use?
Each testing method has its advantages, so consider your situation and the level of detail you need when deciding which test is best for you. Please keep in mind, that the best radon test to use is any test!
- Short-Term Test Kits are ideal for initial screening and quick results.
- Long-Term Test Kits provide a more detailed average radon level as the sample is collected over an extended period, making them suitable for comprehensive assessments. Since radon levels can fluctuate with changing seasons, temperature, and weather, long-term tests help you understand a more full picture of the radon levels in your home.
- Continuous Radon Monitors (CRMs) provide electronic results within a short turnaround time and include a more detailed analysis with continuous active monitoring technology for a more detailed understanding of your radon risk.
What is a Safe Level of Radon?
The EPA recommends taking action at 4.0 picocuries per liter or higher. Since no radon level is completely safe, homeowners should aim to reduce radon as much as possible.
What Comes After Radon Testing?
If radon is detected in your home, taking steps to mitigate is crucial for ensuring a safe living environment. A licensed radon professional can assess your situation and recommend an appropriate solution tailored to your home’s needs.
Radon mitigation involves the process of ventilating radon gas out of your home. Depending on your home’s construction, radon is usually collected from beneath concrete slabs or membranes and then vented outside through a pipe system that extends from the ground up through or past the roofline. A fan, which can be installed in the attic or on the outside of the home, helps to draw radon gas out of the soil beneath the foundation and exhaust it safely into the outdoor air.
Many mitigation systems include alarms to alert you if the system stops working. We recommend having your mitigation system inspected each year to ensure performance.
The installation of radon mitigation systems can often be completed within a day, though this timeframe may vary depending on factors such as the size and layout of your home and the type of foundation. After installation, be sure to have a follow-up radon test conducted to be sure the installed system is working to reduce radon in your home to the lowest possible level.
