Abstract

The results obtained utilising radiochromic films (Gafchromic MD-55 and HD-810, ISP Technologies Inc.), radiographic films (Kodak EDR2) and laboratory-made Fricke-xylenol-orange-infused gel dosimeters in form of layers have been intercompared. Dose calibration curves have been attained for all kinds of dosimeters and in-phantom measurements have been performed. From the detected in-phantom dose images, depth-dose profiles have been extracted and compared with reference values obtained with an ionisation chamber. The performance of the different dosimeters, their precision and reliability, are presented.
