Radon (chemical symbol Rn 222) is an odorless, colorless, radioactive gas. It comes from the natural decay of uranium and radium found in nearly all rocks and soils. Radon can move up from the ground into buildings through openings in floors or walls that are in contact with the ground.
South central Pennsylvania, including York, and Lancaster counties, are classified by the EPA as a high risk zone (Zone 1). Excessive and prolonged radon exposure has been linked to lung cancer.
No matter where you live, test your home for radon. If radon levels in the home are to high, steps can be taken to control the levels of this dangerous gas. The first step is taking a measurement to see if there is a problem.
