Most inhaled radon is rapidly exhaled, but the inhaled decay products readily deposit in the lung, where they irradiate sensitive cells in the airways increasing the risk of lung cancer.
In April of 2002, a Brown Township home on Morris Rd. tested at over 10 picocuries / liter. After professional installation of a Radon Remediation System (cost of $990), the home retested at zero.
According to the US EPA, indoor Radon is the second leading cause of lung cancer in the United States and the leading cause among non-smokers. While about 1 in 15 homes have high radon levels, the ratio is thought to be higher in Brown Township.
Testing is the only way to know your home’s radon levels. There are no immediate symptoms that will alert you to the presence of radon. It typically takes years of exposure before any problems surface and then it is too late. IIf you haven't tested your home, you should. For answers to questions about Radon, please contact:

What is Radon?
|Radon is estimated to cause thousands of lung cancer deaths in the U.S. each year.|
|Radon is a gaseous radioactive element having the symbol Rn, the atomic number 86, an atomic weight of 222, a melting point of -71ºC, a boiling point of -62ºC, and (depending on the source, there are between 20 and 25 isotopes of radon - 20 cited in the chemical summary, 25 listed in the table of isotopes).|
Radon is found all over the U.S.. It is a naturally occurring radioactive gas without color, odor, or taste that comes from the radioactive decay of uranium in soil, rock, and groundwater. It emits ionizing radiation during its radioactive decay to several radioactive isotopes known as radon decay products.
Radon gets into the indoor air primarily from soil under homes and other buildings. Radon is a known human lung carcinogen and is the largest source of radiation exposure and risk to the general public.
* Radon is estimated to cause about 21,000 lung cancer deaths per year, according to EPA's 2003 Assessment of Risks from Radon in Homes (EPA 402-R-03-003). The numbers of deaths from other causes are taken from the Centers for Disease Control and Prevention's 1999-2001 National Center for Injury Prevention and Control Report and 2002 National Safety Council Reports.
