Shermer's stuff is usually good, but this article hinges on a false argument. Many things other than ionizing radiation cause cancer. Electromagnetic radiation is shown to cause small changes in biological function, and that could certainly include accelerating growth or halting programmed cell death, both of which increase risk of serious cancers. Obviously the excess cancer risk must be small or we'd have seen it, so not to worry. I'd much rather see studies on the long-term impact of non-ionizing radiation on overall brain function.
