astrophysical jets apparently coming out of the above-type accretion systems both on stellar and galactic scales.[^1] In a seminal paper, [@BisnovatyiKB-77] calculated the action of radiation on particles in the neighbourhood of a thin disc around a black hole (represented by a Newtonian centre) in their study of various possible consequences of radiation emission on the disc accretion. They mainly analyzed the dependence of particle motion (and of the latter’s aftermaths) on the value of luminosity, assuming this is generated by the relativistic version of the Shakura-Shunyaev “$\alpha$-model" of thin discs due to Novikov and Thorne, and deduced, in particular, that accretion ceases to be possible (at least against the direction of the main energy release) when the luminosity approaches some value around the Eddington one. It was also suggested there that radiation push could “sow" (weak) electric currents and thus electromagnetic field in plasma due to its stronger effect on electrons than on ions.

Next, [@SikoraW-81], [@Piran-82] and [@BodoFMT-85] analyzed the radiation acceleration and collimation of test particles or fluid within funnels of thick discs, assuming a Thomson-type interaction. On the other hand, [@Phinney-82] argued that “the greatly enhanced radiation pressure force felt by a relativistic plasma is accompanied
