A large and growing segment of the population is biologically intolerant of radio frequency radiation – the kind emitted by all cell phones, cell towers, routers and other wireless devices. This week on Green Street Patti and Doug discuss some good news about a new type of plastic, what scientists are learning about microplastics in Pennsylvania, and the renewed debate over the safety of plastic grass fields. Then Dr. Julie McCredden talks about a new study she and her team conducted to determine the extent of electromagnetic radiation syndrome (EMR-S) in the populations of Australia, United States and Canada.
