The rules include not carrying a phone in a pocket or bra, using a headset or speakerphone and limiting cell phone use when your signal is weak. Limiting cell phone use for young children, who have thinner skulls and developing brains is a recommendation also included. Some research has suggested that RF energy may cause headaches or hearing loss in kids. Dr. Joel Moskowitz, the director of the Center for Family and Community Health at UC Berkeley’s School of Public Health welcomed the release of the guidelines but pushed for more action.
“Although California’s new cell phone warnings underplay the state of the science, many people consider this action by the largest state public health department to be a significant development,” he wrote. In fact, this is a battle or a real war: in one of the more prominent cases, the Cellular Telecommunications Industry Association in 2013 successfully blocked the city of San Francisco from issuing notices about the possible dangers of wireless use, arguing that the FCC has concluded using cell phones is safe within certain exposure limits.
