Since 2004, the amount of radon present in Pennsylvania air has steadily increased -- an increase that our guest Dr. Joan Casey notes began the same year that the state's first fracking sites became operational. Dr. Casey recently published her findings that quantify PA radon levels, and she joins us to discuss the possible cause of its decade-long spike as well as what PA residents can do to protect themselves from the toxic gas, which is the second leading cause of lung cancer nationwide.
Asked about the importance of checking radon levels in the home -- especially homes near hydraulic fracturing sites -- Casey explains:
"Radon is colorless, it's odorless, but it's also this carcinogenic gas. And so, it is important for people in Pennsylvania to be checking their indoor radon levels because we know that historically Pennsylvania has had a lot of radon, and there are potentially new pathways opening up due to this industry." -- Dr. Joan Casey
