A layman question:
If Faraday cage holes are smaller than the gamma ray wavelength, does it protect against gamma rays? Or is a thick lead wall needed for M-Disc protection? Is it even possible to construct such small cage holes?
gamma rays = electromagnetic waves
Preserving an M-Disc against a nuclear blast seems futile, as the high temperatures can turn even stone into dust. Is there even a practical way to engineer survival in a nuclear blast? (Any physicists? Engineers?)
Here's a guide on making a Faraday cage, but can it also protect against gamma rays?
