Many homeowners are unaware of a hidden health hazard that could be affecting their homes—radon gas. This invisible and scentless radioactive gas can accumulate indoors over time and lead to significant health issues. The good news is that radon testing is an affordable and easy process that can help protect your loved ones.
What is Radon and Why Testing is Important
Radon naturally forms when uranium in soil, rock, and water breaks down. This gas can move up through the ground and enter homes through cracks in floors, walls, and even through water systems. Without testing, you wouldn’t know it’s there until it becomes a danger.
According to the Environmental Protection Agency (EPA), radon is the second most common cause of lung cancer in the United States and the leading cause for non-smokers. Even minimal but prolonged exposure can be harmful, making regular testing highly advisable.
Best Times and Methods for Testing
Professionals recommend conducting radon tests during colder months when homes are sealed, and readings tend to be more accurate. There are two main testing options:
- Short-term tests (2 to 7 days): Useful for quick checks or during property sales.
- Long-term tests (90+ days): Provide more reliable data about annual average radon levels.
You can purchase test kits at home improvement stores or online or hire a licensed expert. If the test shows a radon level of 4 picocuries per liter (pCi/L) or above, it’s important to consider mitigation solutions.
Interpreting Radon Test Results
Here’s what your results may mean:
- Below 2 pCi/L – Generally safe, but retest every few years.
- 2 to 4 pCi/L – Consider mitigation, especially for long-term exposure.
- 4 pCi/L or above – Take prompt steps to reduce radon levels.
If a short-term test shows high results, follow up with a confirmatory test to be sure before taking action.
Reducing High Radon Levels: Mitigation Solutions
If your radon levels are high, don’t panic. There are effective systems designed to lower indoor radon levels by ventilating the gas out from below the home. These often involve fans and piping systems. Whether your house has a basement, crawlspace, or slab foundation, there’s a specific method suited for your structure. While professionals are ideal for installation, capable homeowners can install some systems with guidance. It’s wise to consult your state radon program beforehand.
How Radon Gets Indoors
Radon gas enters homes through:
- Cracks in floors and walls
- Construction joints
- Gaps around pipes
- Unsealed floor drains
- Water sources like private wells
Lower areas like basements are especially vulnerable, so those should be prioritized for testing.
When Should You Test Immediately?
Even though radon can’t be seen or smelled, these signs may indicate a need for immediate testing:
- Recent renovations or finished basements
- Neighbors reporting high radon levels
- Noticeable cracks in the foundation or ventilation issues
- Living in a region known for its high radon levels
Because symptoms take years to show, proactive testing is the safest approach.
Why Routine Testing Is Important
Radon levels can fluctuate due to weather, home upgrades, changes in airflow, etc. Experts suggest retesting every 2 to 5 years, even if previous tests showed low levels. Consider retesting after major renovations, HVAC system installations, or any significant insulation changes.
DIY Kits vs. Professionals
Choosing between doing it yourself or hiring help depends on your needs. DIY kits are affordable and convenient for general monitoring. However, during home sales or if you need certified results, it’s best to bring in a licensed radon specialist.
To ensure accurate results:
- Place the kit on the lowest livable floor
- Avoid high-moisture areas like bathrooms or kitchens.
- Keep windows and doors closed as advised.
Conclusion
Radon may be silent and invisible, but it’s not uncontrollable. With routine testing and prompt action, you can significantly reduce your risk. Whether you’re moving or staying put, periodic testing is a smart move to protect your health and peace of mind.

Frequently Asked Questions (FAQ)
1. Is radon testing really necessary if I don’t live in a high-risk area?
Yes. Radon can be found in any home, regardless of location. Every home should be tested because radon levels vary from house to house—even on the same street.
2. How long does a radon test take?
Short-term tests take between 2 and 7 days. Long-term tests monitor radon levels over 90 days or more for more accurate annual averages.
3. Can I do radon testing myself?
Absolutely. DIY kits are widely available and easy to use. However, for real estate transactions or peace of mind, you may prefer to hire a certified radon testing professional.
4. How much does it cost to install a radon mitigation system?
Depending on your home’s structure and foundation type, mitigation systems typically cost between $200 and $2,500. Financial assistance may be available for qualifying households.
