Electro-Magnetic Field Manual

Nathaniel Rich, a contributor to Harper's Magazine, an editor at The Paris Review, and the author of The Mayor's Tongue, looks at what scientists know and don't know about the health effects of electromagnetic radiation from cell phones and wi-fi. His article "For Whom the Cell Tolls: Why Your Phone May (Or May Not) Be Killing You," on the often contradictory studies on the safety of cell phones and the growing anti-EMF movement, appears in the May issue of Harper's Magazine.
