Radon is one of the most common home health risks people rarely think about, mostly because you can’t see it or smell it. That’s exactly why Radon Awareness Week exists: to remind homeowners that testing is easy, awareness saves lives, and prevention is possible.

What Is Radon (and Why You Can’t Detect It Without Testing)
Radon is a naturally occurring radioactive gas that forms as uranium breaks down in soil and rock. It can enter homes through small cracks and openings in the foundation and build up indoors over time.
Because radon is invisible and odorless, the only way to know your home’s radon level is to test. The U.S. Environmental Protection Agency (EPA) also emphasizes that testing is the first step in protecting your household. EPA: Health Risk of Radon
Why Radon Awareness Week Matters
Radon is widely recognized as the second leading cause of lung cancer. The important takeaway is not panic, it’s prevention. Radon-related risk is manageable when homeowners know what steps to take and when to take them.
If you want quick answers to common questions, our Radon FAQs cover testing, results, and next steps in more detail.
4 Steps to Take During Radon Awareness Week
1) Check Your Local Radon Risk
Radon risk can vary by region and even from one home to the next. Learning about your area is a helpful starting point before testing.
A quick way to begin is using Protect Environmental’s radon level search by ZIP code to see known radon trends where you live.
2) Test Your Home
Testing is the only way to confirm whether radon levels are elevated. Homeowners can use a test kit or schedule a professional test depending on what feels most comfortable.
To learn more about testing options and what to expect, explore our radon testing resources.
3) Understand What Your Results Mean
The EPA recommends taking action if radon levels are 4.0 pCi/L or higher. Some homeowners also choose to reduce radon at lower levels based on risk tolerance and household needs.
For more guidance, the EPA explains what radon is and why it matters here: EPA: What Is Radon Gas?
4) Reduce Elevated Radon Levels with Mitigation
If test results come back high, mitigation is the next step. A properly installed radon mitigation system can reduce indoor radon levels and help improve long-term indoor air quality.

Common Questions About Radon
Can new homes have radon?
Yes. New construction does not prevent radon entry, which is why testing is still recommended.
Do radon levels change over time?
Yes. Weather, soil conditions, ventilation, and home modifications can all affect radon levels.
How often should radon be tested?
Testing every few years, and after major home changes, is a smart long-term habit.
Is radon only a concern in certain areas?
No. Elevated radon levels have been identified across the country, which is why testing matters regardless of location.
Take Action This Week
Radon Awareness Week is a simple reminder that small actions can make a meaningful difference. Check your local risk, test your home, and if needed, explore mitigation options so you can feel confident about the air you breathe indoors.
