Have questions about radon? You're not alone. Here are answers to the most common questions homeowners ask about radon gas.
What is radon?
Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It is colorless, odorless, and tasteless — completely undetectable without a proper testing device.
Is radon really dangerous?
Yes. Radon is the second leading cause of lung cancer in the United States, responsible for about 21,000 deaths per year. For non-smokers, it is the number one cause of lung cancer.
How does radon get into my home?
Radon seeps up from the ground through cracks in foundations, gaps around pipes, construction joints, and other openings. It can accumulate in any enclosed space, especially basements and lower floors.
What radon level is dangerous?
The EPA recommends taking action at 4 pCi/L or higher. Levels between 2–4 pCi/L should also be considered for mitigation. No level of radon is completely safe.
How do I test for radon?
You can use a short-term charcoal canister test, a long-term alpha track detector, or a continuous electronic radon monitor. Electronic monitors like those from GZAIR provide real-time readings with no lab required.
How often should I test?
Test every 2 years as a routine check. Also test when moving into a new home, after major renovations, or after installing a mitigation system.
Can radon be fixed?
Yes. Radon mitigation systems — typically sub-slab depressurization — can reduce indoor radon levels by up to 99%. A certified contractor can assess and install the right system for your home.
Does a new home mean I'm safe from radon?
Not necessarily. New homes can still have high radon levels. However, many are built with radon-resistant features that make mitigation easier if needed.
Is radon only in basements?
Radon is highest in the lowest levels of a building, but it can be present throughout your home. Always test in the lowest livable area.
