Experimentally Determined Calibration Settings for NIST-Maintained Capintec and AtomLab Radionuclide Activity Calibrators for 68Ge Epoxy–Filled Mock Syringes
| Activity calibrator | Calibration setting |
|---|---|
| Capintec CRC-12 | 452 ± 1 |
| Capintec CRC-15R | 442 ± 1 |
| Capintec CRC-35R | 444 ± 1 |
| AtomLab 100 | 10.8 ± 0.1 |
Settings were determined by adjusting setting value until correct calibrated activity value was displayed on instrument readout. Values displayed are averages of 8 determinations of calibration factor (1 for each syringe source), and uncertainty is calculated from SD of mean of those 8 measurements.
