  The model-independent radiative corrections to deep-inelastic scattering of
unpolarized electron beam off the tensor polarized deuteron target have been
considered. The contribution to the radiative corrections due to the
hard-photon emission from the elastic electron-deuteron scattering (the
so-called elastic radiative tail) is also investigated. The calculation is
based on the covariant parametrization of the deuteron quadrupole polarization
tensor. The numerical estimates of the radiative corrections to the
polarization observables have been done for the kinematical conditions of the
current experiment at HERA
