  In this work, we have investigated the phenomenon of acceleration radiation
exhibited by an atom falling into a quantum corrected Schwarzschild black hole.
We observe that the excitation-probability of the atom with simultaneous
emission of a photon satisfies the equivalence principle when we compare it to
the excitation probability of a mirror accelerating with respect to an atom. We
also demonstrate the validity of the equivalence principle for a generic black
hole geometry. Then we calculate the horizon brightened acceleration radiation
(HBAR) entropy for this quantum corrected black hole geometry. We observed that
the HBAR entropy has the form identical to that of Bekenstein-Hawking black
hole entropy along with universal quantum gravity corrections.
