Radon Gas Safety & Mitigation
What Is Radon?
Radon is a naturally occurring radioactive gas that comes from soil and rock. It is invisible, odorless, and tasteless, and can enter homes through foundation cracks and openings.
Long-term exposure to elevated radon levels is a leading cause of lung cancer in non-smokers.
Why It Matters
Radon can build up in:
- Basements
- Crawl spaces
- Lower levels of homes
Any home can have elevated levels, regardless of age or construction type. The only way to know your level is to test.
Radon Levels
- 4.0 pCi/L or higher: Take action
- 2.0–4.0 pCi/L: Consider mitigation
- Below 2.0 pCi/L: Lower risk, retest periodically
No level of radon is completely risk-free.
Mitigation (Reducing Radon)
Most common solution:
Sub-slab depressurization system
- A pipe and fan system installed in the foundation
- Pulls radon from under the home
- Vents it safely above the roofline
Other methods:
- Sealing foundation cracks
- Improving ventilation
- Sealing sump pits and crawl spaces
Professional Installation
Radon mitigation systems should be installed by certified professionals and always followed by retesting to confirm results.
Where to Get Help
Reliable radon resources include:
- State radon programs
- Local health departments
- Certified radon measurement professionals
- Certified radon mitigation contractors
Safety Message
Radon exposure is preventable. Testing your home is the first step, and mitigation systems are highly effective at reducing risk.
Test. Mitigate. Retest. Protect your home and your health.
