Radon can be found in the air in homes, schools and office buildings or in well water and prolonged exposure has proved to be the leading cause of lung cancer in non-smokers, causing more than 21,000 lung cancer deaths each year. Radon comes from the natural breakdown of uranium in soil, rock and water and gets into the air. The Connecticut Department of Public Health estimates that about 20% of Connecticut homes have elevated levels of radon gas. Radon gas \u201cBecause radon is impossible to see and smell, people tend to minimize the health effects and ignore the possibility that it might exist in elevated levels in their homes,\u201d said Health Director Patrice Sulik. \u201cResidents can decrease their risk by testing their homes and reducing elevated radon levels when found.\u201d It is recommended that residents test the lowest living area of their homes, either the first floor or finished basement. Testing should be conducted between January and March, when windows and doors are closed and heating systems are turned on. Radon test kits that meet EPA guidelines are available at local hardware stores, home improvement stores and other retail outlets or directly from a laboratory. Kits can also be ordered online from the National Radon Program Services at sosradon.org\/test-kits or by calling the American Lung Association of New England at 1-800-LUNG-USA or 860-289-5401. Elevated radon levels can be addressed by qualified contractors, usually at a cost of about $1,200.
