“One plausible explanation for elevated radon levels in people’s homes is the development of thousands of unconventional natural gas wells in Pennsylvania over the past 10 years,” says study leader Brian S. Schwartz, MD, a professor in the Department of Environmental Health Sciences at the Bloomberg School.

“These findings worry us.” The disruptive process that brings gas to the surface can also bring
heavy metals and organic and radioactive materials such as radium-226, which decays into radon. Most indoor radon exposure has been linked to the diffusion of gas from soil. It is also found in well water, natural gas and ambient air
