Polarization characteristics of gamma-quanta, produced in decays B --> K* + gamma and B --> K + pi + gamma are studied in a general parity non-conserving framework. Polarization characteristics of gamma quanta for perturbative (i.e. shea distance) part of the matrix element of these decays are shown to be universal, independent of the process. Nonperturbative effects however violate such universality. (C) 1997 Published by Elsevier Science B.V.
