Q: What is radon, and how can it affect my property?
A: Radon is a radioactive, colorless, odorless, and tasteless gas occurring naturally as a decay product of radium, and thus radon is not readily detectible or observable by the human senses. Radon is considered a health hazard due to its radioactivity, and studies have shown a link between high concentrations of radon and lung cancer. According to the U.S. Environmental Protection Agency (EPA), radon is the second highest cause of lung cancer after cigarette smoking, and radon causes an average of 21,000 lung cancer deaths per year in the United States.
Radon levels are measured by picocuries per liter (pCi/L). An average of about 1.0 to 2.0 pCi/L is typical for indoor radon exposure, and the EPA recommends immediate remedial action for anything above 4.0 pCi/L.
Radon is produced by the radioactive decay of radium-226, which is found in uranium ores, phosphate rock, which has been mined extensively in Polk County over the years, shales, igneous and metamorphic rocks such as granite, and to a lesser degree in common rocks such as limestone, which is found throughout all of Florida.
Radon typically enters a building directly from the soil through the lowest level of a building that is in contact with the ground. Entry points of radon into a building, particularly an older building, are cracks, gaps, and cavities in the building as well as the water supply.
Of great concern in Polk County is phosphate mining and the impact phosphate mining has had on the environment over the years. Phosphate is typically found buried beneath an approximate 10 to 20-foot crust of ground referred to by miners as “overburden.” Radioactive compounds containing uranium and radium, which are dug up during the mining process, are also buried beneath the overburden and mixed with phosphate. Over many years, houses have been built on land which was extensively mined, particularly in the area between Lakeland and Mulberry along Highway 37 or what is known as South Florida Avenue.
Whenever buying or renting property, it is important to read the fine print. Florida Statute § 404.056 requires that any contract for the sale and purchase or rental agreement for the leasing of any building provides a warning about radon and its dangers. While this statute warns buyers and renters, it does not have much bite. If you are buying a home, be sure to pay close attention to the answers provided in the standard Seller’s Property Disclosure regarding any radon issues and have an attorney review all of the documents. If you are building a new home, talk to your builder about radon prevention measures you can take.
If you are buying or renting a property in an area where there has been extensive mining, you should test for radon. Simple test kits requiring a few days of testing are available online and you can hire a certified radon inspector to test for radon as well. The devil is in the details, and it is important to know your rights when buying or renting property and the impact it can have on your health and the health of your family and loved ones.
