Analysis of sample volume dependence of 125I in a radionuclide calibrator.
Results are presented showing the volume dependence of the measured activity of 125I in Capintec radionuclide calibrators. Errors of up to 76% were encountered for commonly used syringes and vials when the manufacturer's calibration factor was used. Calibration factors have been determined for syringes and vials which reduce errors to less than 2%.
