  The result by Burnett-Kroll (BK) states that for radiative decays the
interference of ${\cal O}(\omega^{-1})$ in the photon energy $\omega$, vanishes
after sum over polarizations of the involved particles. Using radiative decays
of vector mesons we show that if the vector meson is polarized the ${\cal
O}(\omega^{-1})$ terms are null only for the canonical value of the magnetic
dipole moment of the vector meson, namely ${\bf g}=2$ in Bohr's magneton units.
A subtle cancellation of all ${\cal O}(\omega^{-1})$ terms happens when summing
over all polarizations to recover the Burnett-Kroll result. We also show the
source of these terms and the corresponding cancellation for the unpolarized
case and exhibit a global structure that can make them individually vanish in a
particular kinematical region.
