Your confusing neutrons and gamma particles that go
through most
everything to Electromagetic waves that don't.
Umm, dude, Gammas are photons are electromagnetic waves. Wave-particle
duality and all that.
And neutrons are easily stopped by a piece of paper :-).
Faraday shield will stop or siffifiently attenuate EM
waves.
Gammas get through many shields because their wavelength can be
small compared to atom-to-atom spacing in a solid, if they're high
enough energy. At even higher energies other effects take over.
