• We have studied the radiative corrections to the angular distribution and energy spectrum of β rays from polarized nuclei. Explicit formulas of the radiative corrections are given for the angle-dependent and angle-independent terms and for the asymmetry factor, under the assumption of the effective current-current interaction of the V-ρA type for the β decay. The lowest order corrections to the first two are almost the same and depend on the cutoff. The asymmetry factor of the β-ray angular distribution is scarcely affected by the radiative corrections. In particular, these corrections are independent of the cutoff for the GamowTeller transition. It is also shown that the radiative corrections to the β-ray spectrum are consistent with those given by Kinoshita and Sirlin, and Berman and Sirlin. Numerical values of the radiative corrections are tabulated for the β decays, ^<12>B→^<12>C+e^-+ν^^- and ^<12>N→^<12>C+e^++ν.
