FAQ About Radon Testing

Let our A-1 Radon experts answer any further questions you may have about radon mitigation systems.

Should radon be tested when buying or selling a home?

Radon testing is strongly recommended as part of any home purchase and is required by law in some states. Buyers should request radon testing during the inspection period, as elevated levels can be a negotiating factor and should be disclosed by sellers in many jurisdictions. Discovering and addressing a radon problem before closing protects both the buyer's health and their financial investment.

Where in my home should I test for radon?

Radon testing should be conducted in the lowest livable area of your home, as radon concentrations are highest near ground level. If you have a finished basement that you use regularly, test there first. For homes without a usable basement, testing should take place on the first floor, typically in a frequently occupied room like a bedroom or living area.

Does radon affect new construction homes?

Yes, new homes are not immune to radon - in fact, modern energy-efficient construction with tightly sealed building envelopes can trap radon more effectively than older, draftier homes. Many new homes are now built with radon-resistant new construction (RRNC) features, such as a gas-permeable layer beneath the slab and a passive vent pipe. Even with these features, testing is still recommended after occupancy to confirm radon levels are within acceptable limits.

Is radon a concern in schools and workplaces?

Radon is absolutely a concern in schools and other non-residential buildings, as students and employees can spend significant time in these spaces.

The EPA has a specific program called the Indoor Air Quality (IAQ) Tools for Schools initiative that encourages radon testing in educational facilities. OSHA does not currently regulate radon in the workplace, but the EPA recommends that all schools and large buildings be tested, especially those with basement or ground-floor spaces.

Is radon found everywhere?

Radon exists in virtually every part of the world at some level, as uranium is present in varying concentrations throughout the earth's crust. Outdoor radon levels are generally very low and considered harmless because the gas disperses quickly into the open air. However, indoor radon levels can accumulate to dangerous concentrations depending on local geology, building construction, and ventilation.
