Radon And Real Estate In Wilmington Delaware
It has been known for many years that radon gas presents a real danger to human health. When a house is placed on the market in Wilmington, Delaware, it is likely that the potential buyer will ask about radon levels in the house. Of all the potential problems with a house, radon level measurement is among the easiest to determine and, if necessary, mitigate.
What is Radon
Radon is a radioactive gas that is emitted by the natural atomic decay of deposits of trace uranium in soil and rocks. Colorless and odorless, it percolates from the soil and seeps into houses through small cracks in the foundation, sump pump wells, openings left for plumbing, wiring and ducts and other spaces. Common belief to the contrary, radon can enter houses even if they have been built on solid concrete slabs; it is not just found in houses with crawl spaces and basements. New houses are also just as susceptible as older structures. Test surveys have shown that the average radon level in single-family stand-alone houses is 1.3 picocuries per liter of air (pCi/L), although concentrations can get much higher.
The toxicity of radon can cause serious health problems. The Environmental Protection Agency (EPA) reports that radon is the second-highest cause of lung cancer, and that 21,000 lung cancer deaths in the United States are caused by radon each year. The EPA has listed radon as a Class A carcinogen, at the same level as arsenic, asbestos and benzene. A study by the Harvard University School of Public Health describes radon as the single greatest in-house hazard in the U.S.
Wilmington Delaware May Be at a Higher Risk for Radon
Since the presence of radon depends upon local geological structures, some areas have higher levels of radon than others. In Delaware, northern New Castle County has the highest potential for higher than average radon levels in the state. Test surveys have shown that 19% of the houses in the Wilmington, Delaware area have radon concentrations at or above 4 pCi/L. This is a concentration that the EPA considers to be an “action level” at which they strongly recommend installing a radon mitigation system. Of course, since radon cannot be seen or smelled, the only way to determine the level in any given house is to test for it. We can provide fast and accurate testing, the results of which will provide important information for the homeowner and prospective buyer.
Even if the test results show that radon levels are high, there is no need for despair; the transaction does not have to be in jeopardy. After all, any house in the area has a strong likelihood of having high radon levels. We can work with the homeowner to design and install an effective radon mitigation system to lower radon levels. As an added benefit, radon mitigation systems also reduce mold and mildew in houses. Be real estate savvy! Test for radon.
