EMF 5G EMF and Health EMF Gadgets EMF Protection By Ayda Walsh Share Tweet Share Share I get this question fairly often, so I wanted to look into it. First of all, to answer the question: Yes, Aluminum foil, much like Aluminum mesh, does block or will shield against most wavelength radio frequency radiation. But take into consideration the 3 Levels you should be concerned with EF – Electric Fields, MF – Magnetic Fields and RF – RadioFrequecy Waves – so which one do you want to shield for? Now let’s dive into this a bit deeper and find out how, and why, aluminum foil blocks radiation. Since the Aluminum is a conductor of electricity, it forms a barrier often called a Faraday Cage, entirely stopping the radio waves. But if the electricity is on the aluminum – where does it travel to? where does it go? Anytime you have EF – you will also have MF. So Proper grounding is needed if you need to ground . For RF Blocking, you can try this for yourself. Get a large sheet of aluminum foil, lay it out flat, set your cell phone on top and wrap it up. Now try calling it, the phone won’t have any signal. These radio waves are a form of EMF radiation. The aluminum foil acts as a barrier and completely blocks those waves. How useful was this post? Click on a star to rate it!
