I hate people like this because their son could really be sick with something, but they’ve decided it is the WiFi and they aren’t getting him the care he needs. Woowoo people I swear.
Maybe just in the child’s room then, also you might want to ground that Faraday cage if they have anything that could be transmitting WiFi or Bluetooth or even is just a large screen.
Also it needs to be a fine mesh because for blocking 5GHz WiFi you want the hole size to be a 1/20 of the wavelength which comes out to >4mm.
Or an even cheaper solution would be to get one of those large “pet” cages and run a wire straight into the earth hole of a power socket.
Tinfoil works quite well, after aluminium has pretty good conductivity. The problem is not leaving any gaps that are too big in any direction, or you just build a slit antenna by accident.
They’ve been tested (in tongue and cheek). Most tin foil hat designs actually increase peak exposure levels in the brain. In order to reduce it, they need to be closer to a motorcycle helmet, along with mesh visor.
Ridiculous claim aside, if they want a solution they should be setting up like a chicken wire Faraday cage, not making this everyone else’s problem.
But that wouldn’t let them walk around feeling superior.

Maybe there’s a gamma emitting test source in the walls…

You theoretically don’t “need” to ground a faraday cage if you want to block RF. I would do it anyway though.
You’re kinda right about the wavelength thing, but tinfoil would absolutely take care of it.
Two layers if you’re cautious. Separated by some thin non conductive layer, except connected at one point. To the better faraday cage.
The Faraday cages I used to use in a lab testing RF devices, used copper screen.

This is actually really nice.
Even if human rf sensitivity were real, tin foil would work.
You’re sharing actual faraday cage material.
Real EE stuff. Probably better than the cage material that I know that lines MRI rooms.
Yeah, it was some crazy stuff. We used to do mobile handsets, GPS, WiFi and other consumer electronics testing.
We’ve be locked in cages like - https://engineering.ssl.berkeley.edu/faraday-cage/

A tinfoil hat is a portable solution.

Except if you just make a hat it could end up being a shitty ‘parabolic’ dish and concentrate the Wi-Fi in how head.
That kid is going to need to go full baked potato to stay safe.
Copper wire works better I hear
You mean the wire in Flock cameras, right?
