    We show how the physical processes responsible for the spontaneous decay of a dipole atom conspire to guarantee that the spontaneous decay rate of the atom transforms between different inertial reference frames exactly as required by time dilation. The method employed makes use of familiar basic properties of Maxwell's equations and special relativity.
