Dose calibrators are not usually used to measure the activity of pure beta emitting radionuclides. In this work, the activity of 32P sodium phosphate was accurately measured with a Capintec CRC 2 dose calibrator. Using a calibration knob setting of 012 on the 1 mCi range, the 32P dose (in mCi) could be calculated directly simply by multiplying the instrument readout by 10. The dose calibrator response was found to be linear at this knob setting and moderate alterations in geometry produced no significant changes.
