As hydraulic fracturing (fracking) increases- so do indoor levels of radon

April 11, 2015

Indoor radon levels in Pennsylvania have been slowly rising since 2004, around the time that unconventional natural gas development using hydraulic fracturing (“fracking”) began in the state. In our new study published in Environmental Health Perspectives, we found three pieces of evidence that there may be a link between unconventional natural gas development and indoor radon levels across the state.

Historically, Pennsylvania has had one of the biggest indoor radon problems in the country. Why? Much of the bedrock in Pennsylvania contains high levels of uranium, which is radioactive and eventually decays to radium and radon gas. Radon gas can then enter buildings by diffusing through cracks…
