I use a land line to reduce EMF exposure, but I am considering using Skype now and then to make long-distance calls. Skype is a phone service through the computer. To use it, one needs to buy a headset that attaches to the computer with a cord and has a speaker for talking, like the things that call center representatives use or, perhaps, used to use before the advent of wireless technology. I was wondering if, not taking into consideration the use of the computer in general, a headset like this would cause more EMF exposure than a land line.
