Synthesized ceramics of the composition 0.64BiScO3-0.36PbTiO3 with deposited gold electrodes were subjected to irradiation with fast neutrons and gamma rays with a fluence of ~5·1019 n/cm2(γ/cm2) at an energy E>0.1 MeV. The elemental composition of the electrode and the electrode-ceramics interface, as well as the crystal structure of the interface after irradiation, were studied. The experimental results indicate a significant effect of irradiation on the gold electrode and the crystal structure of the interface. Keywords: piezoelectric ceramics, radiation resistance, electrode-piezoceramics interface.
