Primary standardization of (67)Ga radiopharmaceuticals.
The two-dimensional extrapolation technique and dead time extrapolation technique of 4pibeta-gamma-coincidence counting were used to standardize the activity of (67)Ga. The counting results of the two absolute counting techniques showed good agreement while the two-dimensional extrapolation technique could save about 50% of the total counting time in this study. The accuracy of the Capintec CRC-15R radionuclide calibrator used by the radiopharmacy of INER was studied in this research. A new calibration setting number, 99, was recommended to the radiopharmacy of INER in the Bayer 10mL sterile empty vial geometry.
