Description

In the present contribution the superconducting YBCO ρ(T) dependence behavior on the irradiation dose and accumulative time are studied for gamma quanta of Eγ = 132 keV (57Co) and 1,25 MeV (60Co) at room temperature. In both cases, possible radiation effects on grain boundary and intragrain zones are evaluated by means of different gamma ray microscopic interaction models. It was conclude that 57Co gamma quanta (Eγ = 132 keV) modules YBCO ρ(T) dependence behavior through enhanced oxygen vacancy diffusion motions which collapse the electron percolative conduction paths in the grain boundary zones, effects which are not observed by irradiation with 60Co gamma quanta (Eγ = 1,25 MeV), in which case main irradiation effects on the electrical conduction mechanisms are limited to the intragrain zones.
