What Is Radon and Why Should You Care?
You can't see it, smell it, or taste it but radon is the #1 cause of lung cancer in non-smokers. The good news? Understanding it is the first step to staying safe.
Radon is an invisible gas that comes from the ground
Think of it like this: deep underground, tiny amounts of uranium break down naturally — the same way a log slowly turns to ash. As it breaks down, it releases a gas called radon.
That gas seeps up through the soil and can get trapped inside your home. Outside, it's harmless — it just floats away. But inside a closed house, it can build up like steam in a bathroom with no fan.
Radon is radioactive, which means breathing it in over time can damage your lungs. It's the #1 cause of lung cancer in people who have never smoked.
How Does Radon Get Inside Your Home?
Radon sneaks in through the tiniest gaps. Think of your house like a straw sitting on top of the ground it gently pulls radon up and in.
Starts Underground
Uranium in soil and rock naturally breaks down over millions of years. One of the byproducts of this process is radon gas odorless and invisible.
Seeps Into Your Home
Radon rises through the soil and enters through cracks in your foundation, gaps around pipes, sump pits, and even through concrete itself. Your home's natural air pressure actually pulls it inside.
You Breathe It In
Once trapped indoors, radon builds up in the air you breathe every day. Over years, the radioactive particles can damage lung tissue even if you've never smoked.
Is Radon Really That Dangerous?
We get it something you can't even see sounds hard to worry about. But the numbers tell a serious story.
Radon is the second leading cause of lung cancer overall and the #1 cause for non-smokers. The EPA estimates that about 21,000 lung cancer deaths per year in the U.S. are linked to radon exposure.
To put it in perspective, that's more than drunk driving, house fires, and drowning combined. The difference? Those risks are visible. Radon isn't which is exactly why awareness matters
Common Radon Myths Busted
Let's clear up the most common misconceptions about radon. Tap each myth to see the truth.
Brand new homes can have high radon levels too. Radon comes from the ground beneath your house, not from the house itself.
Radon levels can vary dramatically from house to house — even next-door neighbors. Differences in foundation, soil conditions, and home ventilation mean each house has its own unique radon profile.
It’s as simple as a smoke detector. A basic radon test or detector is very affordable and easy to use.
Radon can be found and fixed. Professional mitigation systems are affordable, and some states offer support to low-income families.
Opening windows can temporarily lower radon, but it's not a real solution. You can't keep every window open year-round (especially in winter!). A proper mitigation system works 24/7, rain or shine.
Radon Is Fixable Here's How
Knowing about radon might feel scary, but the solution is surprisingly simple, affordable, and effective.
1. Test Your Home
Start with your free Radon Report Card grade. If it shows elevated risk, use a simple test kit to measure your actual levels.
2. Mitigate If Needed
If levels are high, a certified pro can install a mitigation system usually a vent pipe and fan that redirects radon safely outside.
3. Breathe Easy
Mitigation systems reduce radon by up to 99%. They're quiet, energy-efficient, and last for years. Just re-test every 2 years.
What Do Radon Levels Mean?
Radon is measured in picocuries per liter (pCi/L). Here's what the numbers mean for your home.
Now You Know. Time to Test.
The only way to know your home's radon level for sure is to test it. Kits start at about $15, and digital detectors give you results in real time. It's quick, easy, and could save your life.
