Abstract : Performance of the AFRRI Theratron-80 cobalt-60 unit is evaluated with regard to accuracy of distance indicators and timer, beam alignment, dose uniformity, efficacy of different collimation techniques, effect of distance and field size on dose rate, and both depth and surface dose-deposition patterns. The ionization chambers and procedures used for cobalt-60 dose measurements and calculations are described in detail. These data and other information provide a baseline for periodic quality-assurance tests and for planning the dosimetric aspects of radiobiology irradiations.
