Do new homes have radon?

 
 

Brand new homes should be tested for radon before moving in, as part of the inspection period. Some new homes are built with radon resistant construction techniques. A radon test will identify if mitigation is required by the builder, or if additional functionality is required for pre-installed passive mitigation systems.

Any home can have elevated radon levels, and even homes next to each other can have different levels of indoor radon due to construction and geographic difference. Every home should be tested, old or new, and even if it already has a radon remediation system in place.

Radon testing during the inspection period before moving into a new home is recommended, as it is your only opportunity to ask the the home builder to pay for radon remediation. In many cases, if a passive radon remediation system is already in place, a fan can be added to the systems to increase the draw of soil air and radon gas from under the basement slab.

The EPA recommends that every home be tested for radon. Changes to your home such as additions, remodeling, or even a new roof or siding can change the level of radon inside your home.

What are radon levels in Franklin county, Ohio?

Central Ohio has high radon potential according to the EPA. Average radon levels recorded and submitted to the Ohio Department of Health range from 2 to 4 Pci/L (picoCuries per liter), shown in light blue in the graphic below, to ZIP Codes with averages over 10 Pci/L, shown in red in below.

Although there is no safe level of radon exposure, the EPA Action Level for indoor radon is 4.0 Pci/L. The first step to understanding the radon level inside your own home is to test–this is something you can include with your home inspections when buying a home, or anytime for your current home. Even if you already have a radon mitigation system, the EPA recommends that you test your home every two years–many changes to your home can change the amount of radon trapped inside the living area, including new windows, siding, or roof.

What is radon gas?


Radon is an odorless, colorless, tasteless, radioactive gas. Radon comes from the decay of radioactive uranium that can be found in small amounts in rocks and soil throughout nature. In areas with disturbed earth, and loose fill, like when a home is built, radon escapes from the soil.

Radon gas exposure is the number one cause of cancer for non-smokers, even greater than second-hand smoke. Most people are exposed to radon gas inside their own homes, and this is their greatest exposure to natural ionizing radiation.

Radon gas in Ohio

Central Ohio has relatively high natural concentrations of uranium from glacial deposits and shale, which during radioactive decay, produces radium and radon.

The EPA’s current radon action level is four picocuries of radon per liter of air (4 pCi/L). Most counties in central Ohio have high potential for radon, with predicted average indoor greater than the EPA action level. According to one study cited by Ohio Department of Natural Resources Department of Geological Survey, 38% of Ohio’s 88 counties had average indoor radon levels above 4.0 pCi/L, but Licking County’s average was above 8.0 pCi/L. Seven Ohio counties—Carroll, Fairfield, Franklin, Harrison, Knox, Pickaway, and Ross—had average indoor Radon concentrations between 6 and 8 pCi/L.
