N2 - The largest radiative corrections to the cross section of electron-proton scattering at high energies are associated with emission of photons, real and virtual, by electron. They contain large logarithms coming from soft and collinear photons. Cancellation of the contributions of the soft photons to virtual and real corrections is well known. Less known is the fact that the contributions of the photons collinear to scattered electrons are also canceled for the most of experiments. On the contrary, contributions of the photons collinear to initial electrons as a rule are not canceled. It is shown, however, that these contributions are canceled for the experimental set up suggested by A.A. Vorobev for measurement of proton radius.
