A couple of points: A: A microwave leakage is specified in AU and UK as to be less than 5mW per cm2 at a distance of 5cm from the surface being tested. B: Most modern Microwaves have a 3 stage "filter" to stop leakage, I can not remember what they were or how they operated, as I did the theory 8 years ago when here in Perth AU you had to have a radiation permit to service a microwave oven.
