Radon in Your Home? How to Find Out Before It’s Too Late!

Dor-Mar Radon testing technician

Radon gas is an invisible, odorless, and tasteless radioactive gas that can seep into your home without warning. Long-term exposure to high radon levels is the second leading cause of lung cancer in the United States, making it a silent but deadly threat. If you’re unsure whether your home is at risk, now is the time to take action before it’s too late!

What is Radon and Why Should You Care?

Radon is naturally released from the breakdown of uranium in soil, rock, and water. It enters homes through foundation cracks, gaps around pipes, sump pumps, and even well water. Since it is undetectable without testing, many homeowners remain unaware of the potential danger lurking in their basements and living spaces.

The U.S. Environmental Protection Agency (EPA) recommends radon testing in all homes, regardless of geographic location. Even if your neighbor’s home tested low for radon, your house could still have dangerous levels.

How to Test Your Home for Radon

The only way to know if you have a radon problem is through testing. Here’s how you can do it:

1. Purchase a Radon Test Kit

Radon test kits are widely available online or at home improvement stores. The state of Ohio has free radon test kits available.

There are two main types:

  • Short-term tests (2-7 days) provide quick results but may not show long-term exposure levels.
  • Long-term tests (more than 90 days) offer a more accurate average of radon levels over time.

2. Hire a Professional Radon Tester

For precise results, consider hiring a certified radon professional like Dor-Mar Radon Testing and Mitigation. This is especially important if you are buying or selling a home, as buyers often request professional testing before real estate transactions. 

3. Use a Continuous Radon Monitor

Digital radon monitors provide ongoing, real-time readings, alerting you to dangerous fluctuations. These are ideal for homeowners who want consistent monitoring without repeated test purchases.

Interpreting Your Radon Test Results

Once your test is complete, you’ll receive a radon level measurement in picocuries per liter (pCi/L). Here’s what the numbers mean:

  • Below 2.0 pCi/L – Considered safe, no immediate action needed.
  • 2.0 – 4.0 pCi/L – Moderately concerning; consider mitigation steps.
  • Above 4.0 pCi/L – Dangerous levels! Immediate action is required to reduce exposure.

What to Do If Your Radon Levels Are High

If your test results show high radon levels, don’t panic—there are effective solutions to lower them.

1. Install a Radon Mitigation System

A professional mitigation system uses vent pipes and fans to redirect radon gas outside before it accumulates in your home.

2. Seal Foundation Cracks and Openings

While sealing alone won’t solve the problem, it can help reduce radon entry points.

3. Improve Ventilation in Your Home

Increasing airflow, especially in the basement, can help lower radon levels. However, this should be done in conjunction with other mitigation strategies.

Final Thoughts

Radon is a serious but preventable risk. Testing is the first step to ensuring your family’s safety. If you haven’t tested your home yet, take action today—don’t wait until it’s too late!
