  Radiative corrections are calculated for antineutrino proton quasielastic
scattering, neutrino deuteron scattering, and the asymmetry of polarised
neutron beta decay from which $G_{A}/G_{V}$ is determined. A particular
emphasis is given to the constant parts that are usually absorbed into the
coupling constants, and thereby those that appear in the processes that concern
us are unambiguously tied among each other.
