The influence of gamma irradiation (Co⁶⁰ the dose D = 4,75´10⁴R) on low and infralow dielectric properties of a monocrystals with diffuse phase transition Sr_0,75Ba_0,25Nb₂O₆ (SBN-75) was investigated. The character of the dielectric response was compared with behavior of depolarization currents in not irradiated and irradiated samples. The observable changes of electrophysical properties in irradiated SBN-75 are connected with stabilization polar ferroelectric phase in a field of radiation defects.
