Abstract
Preliminary gamma-ray irradiation has been found to enhance oxygen out -diffusion and degradation of Bi2Sr2Ca2Cu3Oy ceramic superconductor un der vacuum annealing. Recovery of initial characteristics of this mate rial takes place by annealing at 400 degrees C in air. It is suggested that degradation of Bi2Sr2Ca2Cu3Oy ceramic superconductor under gamma -ray irradiation is due to the radiation enhancement of gas change wit h environment.
