title: Routine verification of strength of 137Cs brachytherapy sources using a NaI detector.
abstract: An inexpensive and easy method of calibration of brachytherapy 137Cs tubes is described. Cesium brachytherapy sources are calibrated relative to an NIST-calibrated source. The detection system is a NaI detector and single channel analyzer with the window set on the photo peak.
