The SU(2) Isospin Symmetry of strong interactions has played an important role in the clasification of hadrons. However, this symetry is broken by the mass difference of up and down quarks and by the electromagnetic interactions. We show the evaluation of the widht diference between charged and neutral rho (770) meson (Isospin I=1), where the radiative corrections were made using the treatment of Yennie and Meister (1963) in order to obtain the called "independet model radiative correction". This result can be useful in the study of the muon anomalous magnetic moment.
