I'm guessing that's because the regulation was developed way before WiFi was around? > I believe that the maximum allowed level is 5mW/cm^2.

Are you sure? 630W is a lot of radiation. I would be pretty uncomfortable 1 m from an incandescent bulb that put out so much power. And the microwave is tuned to boil the water inside my cells... > Of course, any leakage is likely to be in a narrow > range of angles, so let's say that 1/1000th of the surface has > 5mW/cm^2. This is still 600mW of radiation - much more than any > home-based wifi transmitter (which would be about 10mW). I'll see what my spouse thinks about wrapping the microwave in foil, so we could watch our movies uninterrupted.
