If there is something to worry about with wireless radiation, look to your cell phone. It is used much closer to your body than a smart meter is going to be. In addition, the smart meter is outside your house, adding a further level of attenuation. The strength of the wireless signals falls off with distance according to the inverse square law. Double the distance and the signal drops by one quarter. If you used your cell phone placed one foot away from your head with a head set and your smart meter is 10 feet way, then your cell phone is producing 100 times more non-ionizing wireless radiation than the smart meter.
