  In the Standard Model of electroweak interactions and in the
tree--approximation we calculate the rate and branching ratio of the neutron
radiative beta decay with one-real photon emission by taking into account the
contributions of the weak magnetism and proton recoil to order 1/m_p of the
large proton mass m_p expansion. We find that the obtained contributions of the
weak magnetism and proton recoil increase the rate and branching ratio of the
neutron radiative beta decay by about 0.70%. This is large compared with the
contribution of the weak magnetism and proton recoil of about 0.16% to the rate
of the neutron beta decay, calculated in Phys. Rev. D88, 073002 (2013).
