Lead foil can stop EMR too-- and is available for about $100 for a roll a foot by 5 feet- I think. I might start putting up lead-foil on all my walls and cielings... and make a lead-foil hat-- although there is better EMF protective clothing. Of course, that assumes I have the time and money which I don't... furthermore, there are food shortages being enginneered to take it all down in September... 2022. In any case, I'm relying on the background quantum aether universe to have me "saved" and "alive and well" since I now think that I am a telepresence projectiona and my brain is a quantum transciever from the more basic universe of quantum reality.
