      Introduction: The use of gafchromic films is nowadays essential in radiotherapy. EBT3, which have succeeded to EBT and EBT2, are the subject of this work. Previous studies (1-2) have notably focused on new calibration methods: rational functions (3) and use of the three colors (4). These methods are discussed here in order to determine the most effective way for establishing a single calibration curve used for routine measurements of doses ranging from 0 to 8.5 Gy/fraction.
