Axial anomaly effects in pion and Z0 radiative decays

We discuss a connection between axial anomaly and polarized radiative processes. By comparison with the corresponding unpolarized cases, we consider some physical outputs for the π + and Z 0 polarized radiative decays. We analyse in detail the pattern of mass singularity cancellation.
