The acceleration piezoelectric sensor is a commonly used vibration measurement device in reactor, and its key component is piezoelectric ceramic material. In the environment of intense nuclear radiation, the neutrons and gamma rays interact with the nuclei and electrons in the piezoelectric ceramics respectively, resulting in microscopic damage. Such damage will change the molecular scale and mesoscopic scale, even macroscopic performance, including piezoelectric properties and apparent morphology information of materials, which will bring hidden trouble to the service performance of devices. The effects of long-time and high-dose gamma ray irradiation on the properties of piezoelectric ceramics have been studied, but the effects of short-time and high-dose gamma irradiation on the properties of piezoelectric ceramics has little study. In this paper, the piezoelectric ceramic materials were irradiated with high-dose rate gamma on the radiation device, and then the piezoelectric properties and apparent morphology of the materials before and after irradiation were tested. The influence of high-dose rate irradiation on the properties of piezoelectric ceramics was analyzed through the test results.
