  The one-loop QED and electroweak radiative corrections to neutrino-deuteron
scattering induced by the neutral current are reexamined, paying a particular
attention to the constant term which has never been treated properly in
literature. This problem is closely related to the definition of the
axial-vector coupling constant $g_{A}$ and requires thorough calculations of
the constant terms in the charged current processes, too. We find that the
radiative corrections to the neutral current induced reactions amount to 1.7
(1.5) per cent enhancement, if the Higgs boson mass is $m_{H}=1.5 \: m_{Z}
(m_{H}=5.0 \: m_{Z})$ This number happens to be close to that given by Kurylov
et al., but we argue that this is accidental.
