The model-independent QED radiative corrections to polarization observables in the elastic scattering of the unpolarized and longitudinally polarized electron beam by the deuteron target are calculated. Two experimental setups are considered: the deuteron target is arbitrarily polarized or the vector and/or tensor polarization of the recoil deuteron is measured. The calculations are based on taking all essential Feynman diagrams into account and on using the covariant parameterization of the deuteron polarization state. The radiative corrections are calculated for the hadronic variables using invariant integration of the leptonic tensor. Numerical estimates of the radiative corrections to the polarization observables are made for various values of the kinematical variables.
