In comparison to wireless electromagnetic radiation, EMFs involving extremely low frequencies could be even more detrimental to the human body. For example, when electromagnetic high frequencies encounter a barrier of conventional metal such as tin, aluminum, copper, steel, lead, etc. they experience signal bounce with very minimal surface penetration if any at all. However, when ELF EMF magnetic fields encounter the same metal barrier they penetrate right through it. One can imagine how vulnerable our bodies are to these forces.
