Abstract:	We calculate the energy radiated by Lorentz electrons accelerated in uniform electromagnetic elds up to O(~). The quantum state for the Lorentz electron is chosen to be some wave packet with the expectation value of the position identical to the classical trajectory. We nd that the quantum correction includes two parts: the radiative dissipation to the background, which depends on the con guration of the wave packet, and the absorption from the background uctuation, which is proportional to the background eld strength. In the case of an electron linearly accelerated in a uniform electric eld, the absorption vanishes. Hence one cannot see the trace of the Unruh radiation by observing the radiation emitted by the uniformly accelerated wave packets.
