I have been asked by someone about Smart Meters and this concern over radiation. I see several articles out there that warn of the risks, but few from reliable sources. When they talk about radiation they mean radio and microwave transmissions, which seems a bit scare tactic-ish. I'd like to be able to pass along some facts. Anybody have some? How powerful are these transmissions? Any moreso that cell phones? How frequent? Why the microwave? While we are awash in a sea of radio transmissions all our waking lives, obviously proximity is key. So attempts to protect oneself from emissions this nearby are - at least in principle - more efficacious than attempts to block distant common sources. However, short of encasing the device itself in layers of tinfoil, I don't see any practical way of reducing exposure. Thoughts? References?
