Unruh-DeWitt detector and electromagnetic radiation from a black hole

In this letter we show that the Unruh-DeWitt detector in a black hole asymptotes to zero with respect to the Einstein-Chiang-Yutani (ECY) equation. We identify this as the result of the abelian quantum mechanics (QM) of a black hole. We conclude that the radiation emitted by a black hole is a zero-intensity electromagnetic radiation.
