The cavity-gas calibration factor Ngas for Memorial parallel-plate chambers was determined against calibrated Farmer chambers using two different calibration methods as suggested in the TG 21 protocol. These methods are: (a) 60Co calibration at 5-cm depth; and (b) high-energy electron beam calibration. The Ngas values determined from the 60Co in-phantom calibrations were approximately 1.9% higher than the values determined from the high-energy electron beams.
