    "abstract": "The scheme for accurate quantitative treatment of the radiation from a\ncrystalline undulator in presence of the dechanneling and the photon\nattenuation is presented. The number of emitted photons and the brilliance of\nelectromagnetic radiation generated by ultra-relativistic positrons channeling\nin a crystalline undulator are calculated for various crystals, positron\nenergies and different bending parameters. It is demonstrated that with the use\nof high-energy positron beams available at present in modern colliders it is\npossible to generate the crystalline undulator radiation with energies from\nhundreds of keV up to tens of MeV region. The brilliance of the undulator\nradiation within this energy range is comparable to that of conventional light\nsources of the third generation but for much lower photon energies.",
