Radon is a colorless, odorless gas. It is produced by the decay of uranium, a radioactive mineral found in most soils. The gas seeps into homes and buildings and can reach dangerous levels in poorly ventilated areas. Radon is suspected to come from the radioactive materials that are brought to the surface by the drilling process.

- "A new study by Johns Hopkins researchers links elevated levels of radioactive radon in Pennsylvania homes to the flurry of natural gas wells drilled across the state using the controversial technique known as hydraulic fracturing, or "fracking."
In a paper published online Thursday in Environmental Health Perspectives, researchers with Hopkins' Bloomberg School of Public Health reported that radon levels in Pennsylvania homes have been on the rise since 2004, with the greatest increases in counties with the most wells drilled."

- "Radon is the second - leading cause of lung cancer worldwide . Most indoor exposure occurs by diffusion of soil gas. Radon is also found in well water, natural gas and ambient air. Pennsylvania has high indoor radon concentrations; buildings are often tested during real estate transactions with results reported to the Department of Environmental Protection (PA DEP).
Using first floor and basement indoor radon results reported to the PADEP between 1987 - 2013, we evaluated associations of radon concentrations (ln-transformed) with geology, water source, building characteristics, season, weather, community socioeconomic status, community type and unconventional natural gas development measures based on drilled and producing wells."
