The double-purpose control rods of nuclear reactors were made in which the inserts containing cobalt and europium oxide with natural {sup 151}Eu and {sup 153}Eu content were used as an absorbing core. The mass content of europium oxide is to exceed 15% to provide for a necessary reactivity. Cobalt and europium radionuclides were shown to be accumulated during the reactor operation allowing the inserts to be used as gamma sources after unloading of control rods at large commercial plants for radiation processing of different materials. Shape, geometry and composition of inserts were optimized allowing their specific activity to be obtained above 2 x 10 Bq/g (about 60 Ci/g). The spectral activity and radiation resistance of gamma sources were studied.
