  We present a measurement of the relative branching ratio of the decay KL ->
pi e nu gamma (Ke3gamma) with respect to KL-> pi e nu (gamma) (Ke3+Ke3gamma)
decay. The result is based on observation of 19 000 Ke3gamma and 5.6 x 10^6 Ke3
decays. The value of the branching ratio is Br(Ke3gamma, Egamma^*>30
MeV,theta(e,gamma)^*>20^o)/Br(Ke3)= (0.964+-0.008+0.011-0.009)%. This result
agrees with theoretical predictions but is at variance with a recently
published result.
