The influence of 60Co gamma-irradiation with 1.25 MeV average energy and 1 MGy absorbed dose on electrophysical properties of Cu-, Ni-, Co- and Mn-based spinel ceramic materials in the CuxNi1-x-yCo2yMn2-yO4 ( 0,1 ≤ x ≤ 0,8; 0,1 ≤ y ≤ 0,9-x) system is investigated. The c-induced increasing of the electrical resistance is observed for the investigated samples of various compositions. It is supposed that these changes are explained by cationic redistribution in the spinel sublattices of the ceramics.
