Radon is a naturally occurring radioactive gas given off by uranium found in nearly all soils.  It can become trapped in buildings and build up to high concentrations which can lead to cancer in humans. In fact, radon is the second leading cause of lung cancer, and the leading cause for non-smokers. The NJ Department of Environmental Protection offers extensive information about radon, its sources, testing and how to mitigate. Testing for radon in your home is the only way to know if there is a problem, and testing is recommended once the weather starts to get colder and homes are closed up for the season. Testing can be easily accomplished by a homeowner. Note that prior to the winter season, the Health Department often has radon test kits available - simply call the office to check availability. We encourage residents to have their homes tested, even if a neighbor states they have no problem. It is not uncommon to find homes on the same block with very different test results. Contact the Health Department for more information, test kit availability and guidance.
