The month of January has been designated as Radon Action Month by the United States Environmental Protection Agency (U.S. EPA). Radon is the second leading cause of lung cancer in the U.S. after smoking, and it is the leading cause of lung cancer among non-smokers. Radon is estimated to be responsible for more than 21,000 deaths from lung cancer in the US each year. About 2,900 of these deaths occur among people who have never smoked. Smokers exposed to radon have a much higher risk for developing lung cancer than smokers who are not exposed.
In response to this important public health issue, the Greenwich Department of Health will offer a reduced fee to test radon in air and water. This is being made possible in part by a state grant.
Radon is present at elevated levels in about one of every five Connecticut homes. Radon is a naturally occurring, invisible, odorless, radioactive gas that is normally harmlessly dispersed in outdoor air but can reach harmful levels when it enters and gets trapped in buildings, particularly in the winter months when homes and other buildings are closed up. Radon comes from the ground and can enter a home through small cracks and other openings in the foundation. Dissolved radon can occur naturally in groundwater and may be aerosolized into the air within a home serviced by well water when running faucets, showers, dishwashers or a washing machine.
The Environmental Protection Agency (EPA) recommends radon abatement measures to be undertaken if radon in air levels exceed 4.0 picocuries per liter (pCi/L). Even if the radon test level is below the action level of 4.0 pCi/L, homeowners should consider testing again sometime in the future as radon levels can fluctuate.
