BLOG: Radon Doesn’t Care Where You Live

As a radon professional, you're on the front lines of protecting families. You’re the first, and sometimes the only, professional who gets to assess the invisible risks inside a home. And when it comes to radon, there’s one truth we can’t ignore: Radon is everywhere. And the only way to know if it’s in a home is to test.

For years, many in our industry have leaned on the old EPA radon zone maps to determine whether testing is necessary. But those maps are based on county-wide averages from decades ago. Even the EPA clarifies that:

“Homes with elevated radon levels have been found in all three zones.”

That means every home, in every state, should be tested for radon.

If you’ve ever said, “We don’t have radon in my state,” it’s time to update your thinking. One example is Florida, where the Department of Health has found that 1 in 5 homes have elevated radon levels(1).

That’s why testing in Florida is now required in:

● Schools

● Commercial daycare centers (including home daycares)

● Assisted living facilities

● Hospitals and healthcare buildings
​
​

Florida isn’t alone. States like Texas, and others previously labeled “low-risk” are showing elevated levels as testing increases (2,3). These states weren’t exempt, they just weren’t testing.

For instance, Randall County Texas, reports an average of 17.8 pCi/L (4), over four times the EPA's recommended action level and a record radon level of 7,879.3 pCi/L, was recorded in a building in Dallas County (5), one of the highest levels documented nationwide. ​

Radon knows no borders. It doesn’t follow county lines or zoning maps. It comes from the ground, and levels can vary dramatically from one house to the next, even next door. The only way to protect your client is to recommend a test in every home.

After the pandemic, people finally began paying attention to indoor air quality. More recently, wildfires have pushed air into the headlines again.
But we have to make sure radon stays part of that conversation. Because when the smoke clears, radon is still there.

We believe the future is in new interactive mapping, education, and empowering consumers (6). People want to understand their own exposure. They want tools. And they want to take action for their health, not just hear about risks.

Professional radon monitors like the Airthings Corentium Pro are becoming essential tools in this shift by providing accurate, on-the-spot readings that guide smarter decisions and empower both measurement professionals and homeowners to act confidently regarding healthier indoor environments.

We’re seeing more collaboration, more innovation, and more interest than ever before. That’s exciting. That’s hopeful. And most importantly, it’s working.

You’re not just inspecting homes. You’re giving families peace of mind. And when you recommend a radon test, you’re protecting futures.

Leave the outdated maps behind and move forward with real data and real action. Radon doesn’t care what state you’re in. But your clients do. And with every test, you prove that home inspectors aren’t just part of the transaction, you’re part of the solution.
