Calibration of a liquid I-125 source in a syringe.
The calibration of a liquid I-125 source in an older standard dose calibration system is presented. The calibration factor agrees well with factors established by the NIST for newer dose calibration systems. The determination of the source activity is necessary to accurately calculate the time required to deliver the prescribed dose.
