Strange and nonstrange axial-vector meson radiative decays contribute to photon production in hadron gas. One- and two-hadron radiative decay modes of [ital b][sub 1](1235), [ital a][sub 1](1260), and [ital K][sub 1](1270) are studied. At 200 MeV temperature and for a narrow range in photon energies they contribute more to the net thermal photon production rate than [pi][rho][r arrow][pi][gamma], [pi][pi][r arrow][rho][gamma], or [rho][r arrow][pi][pi][gamma]. They provide significant contribution to the rate for photon energies as high as 1.5--2.0 GeV. For higher energies they are less important.
