The Sun Sentinel says the U.S. is preparing to launch an investigation into the matter, and quotes Gary Brown, an adjunct professor in technologies at Nova Southeastern University, as saying people don’t realize the issue of cell phone safety has not been settled.“The industry says there’s no problem and the public remains ignorant. Adults can do what they want, but where the issue becomes critical, is with children,” Brown said.
