Do Metal Roofs Attract or Block EMF?

WebSep 19, 2024 · Different metals possess different levels of conductivity. Gold is among the highest conductivity of any metal, closely after that comes Silver, then Copper. Aluminum is also a very good conductor for radio frequency waves. However, EMFs can pass right through steel and lead (even though lead can block X-ray frequencies). WebNow I would draw the simple conclusion that atleast one part of EM radiation must not be penetrating any metal surface and since EM radiations cannot survive solely as E or M radiation any sort of radiation penetrating metal surface must not be possible.
