Abstract :
The application of the 4πPC—γ extrapolation-coincidence method for the absolute standardization of 22Na, 58Co, 65Zn, 192Ir is presented. All of these radionuclides decay by beta plus/minus-electron capture processes. Special techniques were applied to assure linearity conditions and to measure the annihilation quanta summation effect.
