June 17, 2025 – Homeowner.org, a leading resource for homeownership education and safety, today announced the official release of Version 1.0 of its interactive Radon Risk Map – a free tool designed to help homeowners, renters, and real estate professionals understand potential radon exposure risks across the United States.
Accessible at Homeowner.org, the new map allows users to explore radon levels by state and ZIP code, making it easier than ever to identify areas with elevated radon risk. Built using public EPA data and local testing insights, the tool empowers Americans to take proactive steps toward a safer home environment.
“Radon is the second leading cause of lung cancer in the U.S., yet many people don’t realize it could be lurking in their homes,” said a staff member at Homeowner.org. “We built the Radon Map to make radon risk visible, understandable, and actionable – especially for families moving into new homes or those considering radon mitigation.”
The Importance of Regular Home Testing
While the Radon Map is a powerful starting point, individual testing remains essential. Radon levels can vary significantly between homes—even in the same neighborhood—due to differences in soil composition, foundation structure, ventilation, and home maintenance.
Homeowner.org recommends that:
- All homeowners test for radon at least every 2–5 years, or after major renovations
- New homebuyers test before or shortly after moving in
- Residents in high-risk areas consider continuous monitoring with digital devices
Regular testing helps homeowners detect long-term exposure risks and respond early with ventilation or mitigation solutions.
Affordable and Reliable Testing Devices
Several cost-effective options are available for homeowners who want to test or monitor radon levels in their homes:
- Airthings Wave Plus – A smart monitor offering continuous radon tracking, air quality insights, and smartphone alerts
- Radon Eye RD200 – A fast, accurate digital radon detector with real-time readings and app connectivity
- First Alert RD1 – A trusted short-term charcoal test kit ideal for initial checks (mail-in lab analysis included)
- Safety Siren Pro4 – A plug-in radon gas detector with an LED display and built-in alarm for high levels
All devices are available online and in home improvement stores, with prices ranging from $20 (for test kits) to $200+ (for smart monitors).
Key Features of Radon Map v1.0:
- Search by ZIP code to check estimated radon risk in your area
- EPA radon zone overlays for easy reference
- Responsive, mobile-friendly design
- Free and open to the public – no sign-up required
Future updates will include filterable data layers, additional mitigation resources, and the ability to report test results anonymously to improve the data set.
