Since the invention of radar, cell phone radiation was assumed to be harmless because it wasn't like X-rays. But a sea change is now occurring in the way scientists think about it. The latest research ties this kind of radiation to lowered sperm counts, an increased risk of Alzheimer's, and even cancer. In Disconnect, National Book Award finalist Devra Davis tells the story of the dangers that the cell phone industry is knowingly exposing us-and our children-to in the pursuit of profit. More than five billion cell phones are currently in use, and that number increases every day. Synthesizing the findings and cautionary advice of leading experts in bioelectricalmagnetics and neuroscience, Davis explains simple safety measures that no one can afford to ignore.
