this is also why one of the first and easiest things you can do to reduce your exposure to RF is earthing... earthing causes the electrons to travel over the surface and not penetrate beyond the conductive part just under the skin... ELF doesn't really affect us as much, though of course it disrupts our organism to not properly receive that frequency range as a mechanism for assisting the endocrine system to set its clocks correctly (sounds like you probably have read Kruse also)
earthing increases reception of this earth cavity and reduces the interference of coincident frequencies in the "dirty power" of our household wiring... this is also why it's really important when checking all this stuff to make sure that the whole earth circuit of your house is fully connected and of sufficiently low resistance (generally earth wires can conduct the whole current of the two phases so it's pretty much just continuity you need to check for)
earthing does not protect from high frequency ionising radiation though, but it covers you all the way up to the top of the microwave spectra
you probably have seen these silly RF shielding clothing items that some people are making... these are dangerous without earthing, kinda sad to be that far towards it and so critically wrong on this point... without earthing the shield doesn't work, it just becomes an accumulator... maybe also you know of Reich's work on this
an ungrounded faraday cage is an orgone accumulator and likewise radio frequency emissions other than the earth cavity resonance build up inside it and become much worse than they otherwise would be
