The paper treats the application of the 4π(PC)β-γ coincidence method for the standardization of the radionuclides 64Cu and 68Ga. The general coincidence equations are written. Two types of extrapolation were described and used in measurement: the positron-annihilation coincidence, and the counting of all emitted radiations; both methods are compared with respect to results, advantages and drawbacks. The impurities' content correction was applied. The standardized solutions were used to calibrate the ionization chamber CENTRONIC IG12/20A and to determine the gamma-rays emission intensities.
► 64Cu and 68Ga were standardized by the 4π(PC)β-γ coincidence method. ► Efficiency extrapolation was applied in two variants. ► Comparison with the gamma-ray spectrometry result was done. ► Ionization chamber CENTRONIC IG12/20A was calibrated for both radionuclides.
