Re: inverse square law and all that


However, I do seem to recall that only microwave ovens work at a frequency that can actually affect living matter; phone, satellite and radio pass through us and do not affect us.


I'm afraid you recollect incorrectly. The human body will block (i.e. absorb) EM over a wide range of frequencies that encompass cellphone, WiFi and satellite broadcasts. Walk in front of a satellite TV dish and the signal will be lost, for example. If the body is absorbing the energy, then that energy is being dissipated inside the body and will cause changes. Whether the changes are sufficient and of a nature to cause any damage or symptoms depends on the field strength as well as the frequency. I would not want to stand next to a WiFi router or hold a cellphone to my ear if they were running the same transmit power as my 800W microwave oven!
