Radiative decays of mesons, both V ..-->.. P..gamma.. and P ..-->.. V..gamma.., are calculated in a relativistic quark model of hadrons proposed earlier by one of the authors. The matrix elements for the above processes are calculated directly by considering appropriately Lorentz-boosted hadronic states. The electromagnetic current operator in terms of the appropriately Lorentz-boosted quark field operators are utilized. Only the wave functions of hadrons enter the picture. No vector dominance is assumed. Mixing angles of mesons are taken from quadratic mass formula in SU(3). Thus with no adjustable free parameters or concepts, there is reasonable agreement with experimental results.
