Precise Radon Testing in Casco

There is technically no "safe" level of radon, but the EPA recommends taking action to reduce radon in your home if levels reach 4 pCi/L or higher. The average indoor radon level in the United States is approximately 1.3 pCi/L, while outdoor air typically measures around 0.4 pCi/L.

Because radon is invisible and odorless, testing is the only way to know whether your home has elevated levels. The EPA and the Surgeon General recommend that all homes below the third floor be tested, regardless of location or construction type. Early detection gives homeowners the opportunity to take corrective action before long-term health consequences develop.

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.

Radon is a naturally occurring, radioactive gas that forms from the decay of uranium found in soil, rock, and water. It is colorless, odorless, and tasteless, making it completely undetectable without specialized testing equipment. Radon is classified as a noble gas, meaning it does not chemically bond with other elements, which allows it to move freely through soil and building materials into indoor spaces.

Yes, radon levels are strongly influenced by the geology of an area, with some regions having much higher concentrations of uranium and radium in the underlying rock and soil.

The EPA has created a radon zone map that divides U.S. counties into three categories based on predicted average indoor radon levels. States in the Midwest, Mid-Atlantic, and Mountain West regions tend to have higher radon levels, though elevated radon can occur anywhere.
