First, the best way to protect against EMP is to not use electronics at all. Smaller circuits are more prone to damage. Most older diesel engines
require no electricity whatsoever to run, so an old Mercedes diesel, before the mid 80's, would survive just fine.
That said, equipment can be (and is) protected. Lead is not any better for shielding than any other metal (what matters is conductivity, not
density).... Most "hardened" systems have some sort of metal shielding around very sensitive items, along with surge arresters to handle excess
voltage from exposed circuits. They will also temporarily shut off automatically when an event is detected to prevent data corruption, and then
