I have a series of 5.8GHz Digital wireless digital phones from Radioshack. There are about three, and each one has its own little charging-thing that simply plugs into an electrical outlet. Each charge-thing then transmits a signal to the main station in another region of the house, with that one going into the phone line. Do these types of wireless home phones emit any radiation at all? And if so, is it sufficient enough an amount to do much of anything at all?
