News release: “Amid concerns about possible health risks associated with cell phones, the Federal Trade Commission advises consumers to avoid products that supposedly “shield” users from cell phone emissions. According to the FTC, the nation’s consumer protection agency, there is no scientific proof that so-called shields significantly reduce exposure from cell phone emissions. In fact, products that block only part of the phone, such as the earpiece, are totally ineffective because the entire phone emits electromagnetic waves. By interfering with the phone’s signal, phony shields may cause it to draw even more power and possibly emit more radiation.
