One of the biggest misconceptions about radon gas is that if the property has a crawl space, the crawl space venting will dissipate the gas to the outside. WRONG! I have been doing home inspections in the Nashville, TN area the past few days, and on two of the properties, the buyers requested that I do a Radon test. Both properties were located in the Sevier Park area off Granny White Pike just south of I-440. One was new construction and the other was a 1950's property. Both had Radon Levels above 20 pCi/l (pico Curies per liter). According to the EPA, any reading above 4.0 pCi/l is considered elevated and must be mitigated. It does not matter if the property has a crawl space or is built on a slab. The geology under the property determines if the property will have elevated levels of Radon.
Middle Tennessee is considered a high radon belt and it is highly suggested, that as a part of the property transaction, a Radon test be conducted. The buyers of these properties were glad they did. The $125.00 test saved them about $1000.00 in remediation costs. Radon is the second leading cause of lung cancer in the United States second only to cigarettes.
