dc.description.abstract	We evaluate radiative decays of rho and omega going to two neutral mesons, pi(0)pi(0) and pi(0)eta. We use the sequential vector decay mechanisms in addition to chiral loops and rho-omega mixing. The chiral loops are obtained using elements of UchiPT successfully applied in the study of meson-meson interactions up to 1.2 GeV. The chiral loops are found very important in the case of the rho --> pi(0)pi(0)gamma decay and small in the other cases. A good agreement with present measurements of rho --> pi(0)pi(0)gamma and omega --> pi(0)pi(0)gamma is obtained and predictions are made for the other decays where the rates obtained are rather small.
