I wouldn't be too hard on Barry Trowers, he shares a valid test. A microwave oven is nothing more than a RF transmitter in a box: a Faraday cage. I will use the frequencies shared on this thread: 900Mhz to 2400Mhz, 1.0 - 0.1 meter wavelengths in air, both are within the UHF bandwidth. Faraday cages are designed to shield against electromagnetic energy by providing more induction through the metal of the cage rather than through the air around it. They do not offer protection from the total spectrum of electromagnetic waves; however, a cage can be "tuned" to the frequencies in use by the design and dimensions of the cage interlacing. I submit that a properly designed microwave oven should have the capacity to shield from both of these frequencies within the UHF bandwidth. Draw your own conclusions
