Berkeley sued over mandatory cellphone radiation warning
July 27, 2015, 7:43 AM|Berkeley, California, is in a battle over what it can say about cell phones and cancer risk. An ordinance set to begin next month requires cell phone retailers to post a warning about potential radiation danger, but a lawsuit put the measure on hold. A wireless trade group says it violates businesses’ First Amendment rights, forcing them to share false information. New York Times science columnist John Tierney joins “CBS This Morning†to discuss the controversy.
