  Consequences of anisotropic cascade radiation in AGN are investigated. The
anisotropic cascades are produced by protons accelerated in a nuclear jet. The
protons are assumed to cool in the UV photon field of an accretion disk by
photo-production of secondary particles. Most cascade photons are produced in
the direction of the accretion disk leading to strong high-energy irradiation
and weak emission of observable MeV photons. Nuclear, turbulent jets rapidly
disrupt and remain radio-faint, so that the scenario could hold the clue to the
understanding of the X-ray spectra of radio-quiet AGN.
