That's close to what I've measured my phones to generate during a conversation. If you are using say a wired headset or bluetooth earpiece, and the receiver is a few feet away it is not nearly that high. A mobile phone uses up to about a watt when active and a microwave uses about 1000 watts. Otherwise a mobile phone doesn't generate EMR, unless it being used for some other kind of digital communication.
For WiFi (or 3G) frequencies the FCC limit is 1000 microwatts/cm^2. WiFi exposure is on the order of 0.001 to 0.01 microwatts/cm^2 even when you are just feet away from the base station. (And it falls off as 1/distance^2.) http://www.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet56/oet56e4.pdf (page 15) http://en.wikipedia.org/wiki/Mobile_phone_radiation_and_health ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
