Home Buyers In Chattanooga Tennessee Are Now Aware Of The Dangers Of Radon

Chattanooga Tennessee Radon Real EstateWhen placing a house up for sale in Chattanooga, Tennessee, it is important to keep radon levels and radon mitigation in mind. Buyers often are concerned with this issue and it is best to be prepared for their questions. Of all the potential problems associated with a real estate transaction, however, radon levels are the simplest to determine and mitigate.

Radon is an odorless and colorless radioactive gas which is a by-product of the atomic decay of naturally occurring uranium. It percolates through the soil and seeps into houses through cracks, plumbing, wiring and duct openings, sump pump wells and other spaces into houses. Despite common belief, radon can enter houses through slab foundations as well as houses with crawl spaces and basements. Measured in units of picocuries per liter of air (pCi/L), test surveys have shown that the average concentration of radon in single-family detached houses is 1.3 pCi/L.

Do Not Put Your Family in Contact With Radon

As a radioactive gas, radon is considered to be a Class A carcinogen, on par with arsenic, asbestos and benzene. The Environmental Protection Agency (EPA) states that it is the second-highest cause of lung cancer, responsible for 21,000 deaths in the United States each year. A study by the Harvard University School of Public Health ranks radon as the single most important in-house hazard in this country, while the National Research Council has stated that radon is one of the major environmental toxins in the U.S. Although not everyone who breathes radon gas develops lung cancer as a result, the EPA considers levels at or above 4 pCi/L to be an “action level” at which radon mitigation to reduce the level of the gas is strongly recommended.

Chattanooga Residents May Be at a Higher Risk of Radon Exposure

The geology of Tennessee lends itself to two bands of high levels of radon-bearing rock and soil. One runs north-south in the central part of the state, while the other follows the southern Appalachian Mountains in the eastern section of Tennessee. Since Chattanooga, in Hamilton County, lies on the western edge of the Appalachian Mountains, it has a higher-than-average incidence of radon. Test surveys show that 16% of houses in Chattanooga have radon concentrations of at least 4 pCi/L. Since the presence of radon is dependent upon very localized geological and soil conditions, the only way to determine if a particular house has high levels of the gas is to perform a radon test. We can offer fast and accurate tests, providing important information to homeowners and potential buyers.

If the result of a radon test indicates high concentrations, it does not mean that the real estate transaction cannot take place. We can work with the sellers and buyers to design and install an effective radon mitigation system to reduce the radon levels, which not only protects the health of the house’s occupants but preserves the market value of the house as well. As a side benefit, radon mitigation systems also reduce the growth of molds and mildew.
