Abstract: We study a number of issues related to the emission and absorption radiationby non-relativistic electrons within the framework of a Lorentz-breakingelectrodynamics in 3+1 dimensions. Our main results concern how Planck-likespectrum law is sensitive to terms that violate Lorentz symmetry. We haverealized that Planck law acquires extra terms proportional to the violatingparameters: for the CPT-odd model, the leading extra terms appear to be linearor quadratic in these violating parameters according to the background vectoris parallel or perpendicular to the photon wave-vector. In the CPT-even case alinear `correction- shows up. Among other possible ways to probe for theseviolations, by means of the present results, we may quote the directobservation of the extra contributions or an unbalancing in the mean occupationnumber of photon modes in a given thermal bath.
