Low Dose Rate Brachytherapy Source Models

The UWADCL is capable of calibrating the following low energy brachytherapy sources, or applicable well chambers utilizing them. All sources are calibrated in units of air kerma strength (U). For I-125, Pd-103, and Ir-192, each source model is a separate calibration point. The Cs-137 calibration point will cover most tube-type sources in the medical community.
