Doped PZT ceramics, with the chemical composition (Pb0.9Ba0.1)(Zr0.53Ti0.47)O3+ 2% mol. Nb2O5was the tested material. It is characterized by high dielectric values (e > 1300, tgd = 0.024) and electromechanical coupling coefficient (kp> 0.5). Due to good mechanical parameters (E = 102 GPa at T = 293 K) and high stability of parameters at elevated temperatures, the ceramics is used in electromechanical transducers at low frequency. Objective of this work was the investigation of the gamma radiation influence of the electromechanical properties of such ceramics.
