Hawking black hole(BH) radiation is emitted when particles tunnel from the inside through even horizon to the "outside world". We here show that atoms falling from outside through a Schwarzschild horizon emit Unruh acceleration radiation which to a distant observer looks much like Hawking radiation. In particular, we find the entropy of the acceleration radiation via a simple laser-like analysis.
