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 Wilmington Delaware Real EstateRadon 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.
