The aim of the present work is studing the influence of gamma irradiation on the superconducting properties
of TlBr2Ca2Cu3O9-δ compound, at room temperature by using 137Cs source with dose 10,20 and 30 MRad. Specimen has
been prepared by solid state reaction process. Superconductor properties and X-ray diffraction (XRD) studied before and
after irradiation. It is showed that our compound has tetragonal structure correspond to the 1223 phase with decreasing
of the ratio c/a due to gamma irradiation. In addition, the transition temperature (Tc(on)&Tc(off)) were decreasing from 110
to 85 K, and 129 to 117 K respectivelya,when the dose increasing from 0 to 20 MRad and increase Tc(on) to 119 K &Tc(off
132 for dose 30 MRad.
