It's called a Faraday cage. Never underestimate the power of a grounded Faraday cage to block EM radiation, LOL.
You can get netting that blocks or disrupts EM waves. The tinfoil hat approach is a bit random. It will reflect waves, but possibly concentrate them in random areas.
I would think a tin hat may need to be grounded too, or it's an antenna, not a shield.
Maybe why they treat lead like asbestos...a lead lined helmet would probably help.
