I’d like to break that question down into a few bits:

If a planet is within the galactic plane, how much would the dust between the planet and the core block and shield it from all those photons being blasted out at all frequencies and super high energy levels, as well as articles like protons and electrons?

If a planet is above or below the galactic plane, maybe, probably, the show in the sky is much more intense… and perhaps deadly? Or does the planet have to be right in the path of the polar jets of an active nucleus to get cooked?
