Understanding Radon and Its Risks
Radon is a naturally occurring radioactive gas that seeps into homes from the ground. It is colorless, odorless, and tasteless, making it impossible to detect without proper testing. Long-term exposure to elevated radon levels is a serious health concern, as it is the second leading cause of lung cancer in the United States, according to the Environmental Protection Agency (EPA).
In Pennsylvania, radon is particularly prevalent due to the region’s geology. Areas like Newtown Square are known to have elevated radon levels, making radon testing a crucial step for homeowners, buyers, and builders.
How Does Radon Enter Homes?
Radon gas is produced from the breakdown of uranium in soil and rocks. It moves through the ground and can enter buildings through:
- Cracks in foundations and basement floors
- Gaps around pipes and utility lines
- Crawl spaces and sump pump pits
- Construction joints
Once inside, radon accumulates, particularly in poorly ventilated areas like basements and lower floors.
Is Radon Testing Necessary?
If you’re wondering, “Is radon testing necessary?”—the short answer is yes. The EPA and the Pennsylvania Department of Environmental Protection (PA DEP) strongly recommend radon testing for all homes, regardless of age or location.
When Should You Test for Radon?
- Before Buying a Home: Many buyers ask, “Is a radon test required when buying a home?” While not legally mandated in Pennsylvania, many lenders and homebuyers require radon testing before finalizing a purchase.
- New Construction Homes: Do you need a radon test for new construction? Yes! Even new homes can have high radon levels. While some new builds include radon-resistant construction techniques, testing is the only way to ensure safety.
- After Renovations: If you’ve recently finished a basement or made structural changes to your home, radon levels may have changed.
- Every Two Years: Radon levels fluctuate due to weather, home ventilation, and soil conditions, so regular testing is recommended.
How is Radon Testing Done?
Radon testing is simple and affordable. You can choose between:
- Short-Term Tests (2-7 days): These are useful for quick assessments, particularly during real estate transactions.
- Long-Term Tests (90+ days): These provide a more accurate reading of annual radon levels in your home.
Certified professionals, such as Batten to Beam Inspections, LLC, use advanced radon detection technology to ensure accurate results.
What Happens If Your Home Has High Radon Levels?
If your radon test results exceed 4.0 pCi/L, the EPA recommends mitigation to reduce radon levels. Common radon mitigation strategies include:
- Active Soil Depressurization (ASD): A vent pipe and fan system draw radon from beneath the home and release it outdoors.
- Sealing Cracks and Openings: Reducing radon entry points can help, but it should not replace professional mitigation.
- Improving Ventilation: Increasing airflow can help disperse radon, though it is not a standalone solution.
