Technically speaking, yes. But they're way off on the other side of the EM spectrum, giving them dramatically different properties. You can shield against radio with a shell of any conductive material -- even a wire mesh for longer wavelengths -- but X-rays are only absorbed by high-atomic-weight atoms, like lead.
Of course the are, but - if I'm correct - they don't produce an electromagnetic field.
And are not shielded by a bit of mesh wire (I work with desktop microCT machines...).
X-rays are the exact same thing as any other electromagnetic radiation, just at a different frequency.
Generally a mesh can block an EMR signal if the holes are < 1/2 wavelength in size. X-rays have nanometer wavelengths so the mesh wouldn’t even be visible to the naked eye.
