"The multiplying sources of radio frequency from wireless devices has driven a vociferous resistance against Pacific Gas & Electric's SmartMeter rollout by those skeptical that low-energy radiation is safe.

Major science organizations support existing federal health exposure guidelines, saying that no evidence shows physical harm from the level of electromagnetic radiation, or EMR, that wireless devices emit.

But these same organizations say that weaknesses in the body of data, and studies that hint at a few unusual responses to low-energy EMR, make it too soon to rule out harm from long-term exposure."
