The Dangers of Radon in Your Home

Your home should be a safe space where you feel at ease. But even if everything appears to be in order, there could be a hidden danger lurking in the air you breathe. It’s called radon. 

Radon is a naturally occurring gas created from the decay of radioactive elements such as uranium and radiumThere are actually trace amounts of radon in most of the air around you. Don’t panic, though. At low levels, radon is harmless.  

When it becomes concentrated, such as in a home, it can become life threatening. 

There are different ways radon can find its way into your home. It could come from the soil beneath your home, seeping through the foundation. It can also be found in natural materials used to build your home, such as concrete or stone. 

Radon can also be found in water, particularly water from underground wells, though this generally doesn’t contribute to radon exposure. 

Since radon is heavier than normal air, it typically gathers in the lowest level of your houseOnce it reaches a high enough presence, it may start to harm your body. 

Radon is the Second Leading Cause of Lung Cancer 

The dangers of radon are real. When breathed in, radon decays, leaving tiny radioactive particles inside of your lungs. These particles latch on to the cells inside of your lungs, damaging them. Prolonged exposure to high levels of radon can cause lung cancer.  

Around 20,000 lung cancer deaths are linked to radon. For smokers who are exposed to radon, the chances of developing lung cancer are significantly higher.  

Those diagnosed with lung cancer have the lowest survival rate of any form of cancer. 

Research has recently suggested that radon may cause other types of cancer as well, including leukemia in children. 

Getting Radon Out of Your Home 

Radon can appear in homes of any state across the US. The only way to know is to get your home tested for radon. It’s estimated that 1 in 15 US homes have radon levels above the EPA’s recommended level. 

Don’t assume you’re safe just because a neighbor’s test came back negative. Radon levels can vary drastically even between houses in the same neighborhood. 

Call a professional and have your home inspected for radon. Radon testing is quick and affordable. For all of your radon mitigation needs in Springfield, Ohio and beyond, contact Air Duct Cleaning & Radon Company. 

Frequently Asked Questions About Radon Testing Before Basement Renovation

Short-term tests typically run for 48 to 96 hours. That’s enough to get a clear baseline before renovation. If you're on a tight timeline, we offer same-day professional radon testing, using calibrated digital monitors with faster turnaround and higher accuracy.

🛠️ Pro Tip: Schedule your test at least a week before framing or insulation begins — that gives you time to take action if mitigation is needed.

Often, yes. Finishing a basement reduces natural ventilation, seals air pathways, and creates negative pressure zones — all of which can trap radon gas inside. We frequently see radon levels double or triple after renovation.

If you plan to install drywall, flooring, or closed-cell insulation, test first. It's much harder to retrofit a system once the space is finished.

Absolutely. In fact, newer energy-efficient homes are often more airtight, which can amplify radon accumulation.
Radon isn’t about age — it’s about soil conditions, slab construction, and airflow. We’ve mitigated brand-new builds in Columbus that tested over 10.0 pCi/L before occupancy.

The EPA recommends testing every 2 years, but after a basement remodel, you should test immediately after the work is complete — even if you tested beforehand.

🎯 And if you already have a radon mitigation system, make sure to re-test after any HVAC upgrades, insulation changes, or new construction that may affect airflow.

  • Below 2.0 pCi/L: No action needed — considered low risk.
  • 2.0 to 3.9 pCi/L: Consider mitigation, especially if children live in the home.
  • 4.0+ pCi/L: The EPA’s action threshold. Mitigation is strongly advised.

🔎 We’ve seen plenty of “borderline” homes spike to dangerous levels after finishing — so if you're anywhere near 4.0 pCi/L, don't wait.

Final Takeaway: Test First, Then Build

The only way to ensure a safe renovation is through early detection. Testing for radon before finishing your basement isn’t just smart — it’s essential.
