X-rays are not produced in lighting when the bolt hits, but before or when it initiates - if the x-ray production in the halo is the same mechanism as that of atmospheric lightning then that means lightning must initiate on the comet and fire outwards, not the other way around.
Can you clarify this? It'd not clear what you mean.
