When they talk about radiation shielding they aren't saying all radiation so I highly doubt they have gamma rays, protons or alpha particles in mind.
They just mean boring old EMF radiation you might have in your home or experience outside that could effect electronics. They seem to be only concerned about an EMF wave or electric field that could produce some impedance or stray voltage on a circuit and little else. Not something exotic like a gamma ray or x-ray, and definitely not any particle matter which would be part of a nuke's radiation blast.
That's a hot take but here is why its wrong!
