What is Radon?

Radon is a radioactive, colorless, odorless, and tasteless gas that forms naturally from decaying soils in the ground. It enters homes through unsealed crawl spaces, foundation cracks, and even water supplies.

The EPA estimates radon is responsible for over 20,000 lung cancer deaths annually in the United States, making testing the only way to know your home's risk level.

How We Test

  • Device placement — radon measurement devices are positioned throughout the home
  • Sample collection — devices collect air samples over a 2–4 day period
  • Lab analysis — samples are sent to an independent laboratory for testing
  • Results delivery — you receive results within 48 hours of sample receipt

Can Radon Be Fixed?

Yes. If elevated radon levels are detected, mitigation systems can reduce concentrations to safer levels. The EPA recommends testing every two years to ensure ongoing safety.

All testing is conducted by our certified Radon Measurement Professionals (RMP) for both residential and commercial properties.

Why Radon Testing Should Be Part of Every Home Purchase

Radon is present in every home to some degree — the question is whether the level is high enough to require mitigation. Because radon is invisible, odorless, and tasteless, testing is the only way to know. Noble Property Inspections deploys EPA-approved measurement devices and uses accredited laboratory analysis to give you an accurate, defensible result.

  • Short-term testing: 48-hour minimum deployment meeting EPA measurement guidelines
  • Accredited laboratory analysis — not home test kit accuracy
  • Deployment at lowest livable level as required by EPA testing protocols
  • Clear report with measured pCi/L levels and EPA action threshold comparison
  • Mitigation referrals available if levels exceed 4 pCi/L

Radon is the second-leading cause of lung cancer in the United States. A mitigation system — typically costing $800-$2,500 — can reduce radon levels by 90% or more. Testing before closing puts the responsibility for mitigation on the seller, not the buyer.

Frequently Asked Questions

What is radon and why is it dangerous?
Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It is odorless and colorless. Radon is the second leading cause of lung cancer in the US after smoking, according to the EPA, responsible for approximately 21,000 deaths annually.
What radon level is considered unsafe?
The EPA recommends mitigation if indoor radon levels are 4 pCi/L or higher. Levels between 2–4 pCi/L should be considered for mitigation. The average indoor radon level in the US is about 1.3 pCi/L.
How is radon testing performed?
We deploy EPA-approved short-term radon measurement devices at the lowest livable level of the home for a minimum of 48 hours. Devices are then sent to an accredited laboratory for analysis and results are delivered within 3–5 business days.
Can radon levels be reduced?
Yes. A radon mitigation system (sub-slab depressurization) can typically reduce radon levels by 90% or more. Mitigation systems are installed by certified contractors and typically cost $800–$2,500.
Is radon testing required when buying a home?
Radon testing is not universally required but is strongly recommended, especially in high-risk areas. Some lenders and states require it. We offer radon testing as a standalone service or as an add-on to any home inspection.
