To Cleopatra:
Prag's comment "When he tells everyone that they are so dangerous, he is ignorant of the fact that most of those fields will never even REACH the inside of the body". is sadly wrong.
For starters the way mobile phones are assessed for impact on users is a statistic called "Specific Absorption Rate ("SAR"), which estimates the level of electric field inside the body as a result of the phone, and using a formula which incorporates conductivity of tissues et alia produces an SAR value for cellphone types. (There is a lot wrong with this approach, but that's another issue). My Motorola phone has an official SAR of 0.9 W/kg for example. The limit is the US (ANSI) is 1.6 W/kg from memory, and in Europe I thinkm it's 2.0 W/kg but this depends on a number of factors e.g frequency. So to say these fields never get inside the body goes against the way all the cellphones in the world are presently evaluated for health impact. These are RF/MW radiations, of course, but ELF fields, being a much lower frequency, are much more penetrative of water (of which we are largely made) which is why the US and other navies chose 76Hz (an ELF frequency), for their communications with submarines.
