Radon Huntsville › Services › Radon Testing
Radon Huntsville is the local starting point for accurate radon testing in Huntsville. Tests are performed by certified radon measurement professionals, often with continuous electronic monitors that record radon hour by hour.
You can also start with a do-it-yourself kit. The Alabama Department of Public Health offers free radon test kits to Alabama households while supplies last. If your result is high, a professional test can confirm it before you mitigate.
Short-term vs. long-term tests
Short-term tests (2 to 90 days)
Charcoal canisters and continuous monitors give a fast reading, often in 2 to 7 days. They're good for a first check or a real estate deadline, but radon changes with weather and seasons.
Long-term tests (more than 90 days)
Alpha track and similar detectors give a better picture of your year-round average, which is what health risk is based on.
How to get an accurate result
- Test on the lowest level you live in or use regularly.
- Keep windows and outside doors closed, except for normal coming and going, starting 12 hours before and during a short-term test.
- Place the test away from drafts, humidity, kitchens and bathrooms, about 20 inches or more above the floor.
- Don't test during severe storms or very high winds if you can avoid it.
- Follow the kit's instructions exactly, and mail it back right away.
If your result is high
If a short-term test is 4 pCi/L or higher, the EPA suggests a second test to confirm. Use another short-term test if you need results quickly, or a long-term test for a better average. If the average is 4 or more, plan to mitigate. See radon mitigation.
Frequently asked questions
Are free radon test kits available in Alabama?
The Alabama Department of Public Health has offered free test kits to Alabama households, typically while supplies last. Check ADPH's radon page for the current offer.
Should I hire a professional or use a kit?
Kits are fine for a first check. Professional continuous monitors are better for real estate deals, confirming a high result, and testing after mitigation.
