Radon gas testing is essential for protecting your family’s health and your home’s value. This invisible, odorless gas poses a serious health risk if it accumulates indoors. Fortunately, with proper testing and mitigation, you can prevent long-term exposure.
In this guide, we explore why radon gas testing is crucial, how radon enters buildings, available testing methods, and how professional mitigation services—like those offered by DSM Radon ensure your environment remains safe and breathable.

Why Radon Gas Testing Matters
Radon gas testing is not just a precaution; it’s a necessary step in maintaining indoor air quality. According to the EPA, radon exposure is the second leading cause of lung cancer in the U.S., following smoking. Unlike visible hazards, radon cannot be seen, smelled, or tasted.
This makes routine radon gas testing all the more important particularly in high-risk geographic areas. It ensures that even invisible threats are brought to light and addressed effectively. You can learn more about radon and its dangerous effects here.
Radon and Its Sources
Radon is a naturally occurring radioactive gas that results from the breakdown of uranium in soil, rock, and water. It’s released into the air and can seep into buildings through gaps and cracks. While outdoor radon levels are usually low and harmless, indoor levels can accumulate and become dangerous.
Due to its radioactive nature, radon decays into solid particles that can attach to lung tissue when inhaled, leading to serious respiratory health problems over time. That’s why radon gas testing is essential in both new and older buildings.
How Radon Enters Your Home
Radon typically enters homes through:
- Cracks in the foundation or walls
- Construction joints
- Gaps around service pipes
- Sump pump openings
- Crawl spaces
Once inside, radon gas becomes trapped and concentrated, especially in lower levels like basements. Even airtight homes are not immune, which reinforces the need for regular testing.
Testing Methods: Short-Term vs. Long-Term
There are two main types of radon gas testing:
- Short-Term Testing
This method lasts from 2 to 7 days. This test provides a quick snapshot of radon levels and is often used during real estate transactions or for preliminary evaluation.
- Long-Term Testing
Lasting 90 days or more, this method offers a more accurate understanding of your average radon exposure over time. It is ideal for making decisions about mitigation.
While DIY test kits are available, professional testing ensures precise placement of monitors, accurate readings, and proper interpretation of results.
How to Interpret Test Results
Results are measured in picocuries per liter (pCi/L). The EPA recommends mitigation if your home’s radon level is 4.0 pCi/L or higher.
However, even levels between 2.0 and 4.0 pCi/L may pose health risks with prolonged exposure. Many experts suggest taking preventive measures even if results are only slightly elevated. A follow-up long-term test can confirm whether mitigation is needed.
What to Do if Radon Levels Are High
If radon gas testing reveals high levels, the next step is to install a radon mitigation system. These systems typically work by:
- Sealing entry points
- Creating a suction point below the foundation
- Venting radon gas above the roofline, away from windows and vents
Post-installation testing ensures the system functions correctly and reduces radon to safe levels. Maintenance and periodic retesting also help ensure long-term protection.
