Point people to something they can understand: the installation manual
of their microwave.  It says that you should put the microwave on its
own 15-amp circuit.  Then point to the weenie wall-wart transformer of
an AP.  It's just common sense that less power is safer.

Yes, for simplistic people that should work. Someone who understands this will realized that 1000W of energy fed into a feed horn that is illuminating a 150' dish is lower field strength at the output of the dish than sticking your Wi-Fi card in your mouth. In the former case the power density is .2mw/cm^2. If I figure that my antenna on my wi-fi card covers about 20 cm^2 (front and back) and that the power is 200mw (+23dbm), the power density is now 10mw/cm^2, still pretty darned low. Don't forget duty cycle and the inverse square law too.


This is all so silly. As Alfred was wont to say, "Make everything as simple as possible, but not simpler." It is like radiation. As soon as you start to talk about radioactive materials people freak out whether there is a threat or not.
