We show that at presence of intense radiation fields, produced by GRBs, relativistic bulk flows can quickly and very efficiently accelerate protons up to the energies limited either by radiative losses or by the condition of confinement in the magnetic field (gyroradius less than the accelerator size). Unlike the traditional model of diffusive shock acceleration, we take advantage of continuous photon-induced conversion of protons to neutrons and back. Such a conversion allows accelerated particles to increase their energies in each particle-shock encounter by a factor on average roughly equal to the bulk Lorentz factor squared. This effect not only leads to copious production of high-energy protons and neutrinos, but also serves as an efficient way of converting the energy of bulk motion into gamma-ray radiation and acts to dissolve the shock front.
