Abstract: | Using 10 and 30 keV photons from synchrotron radiation, we measured optical density curves of GafChromic films MD-55 and HD-810 and compared the results with those of (60)Co gamma rays up to 500 kGy. The scanners used were a fluorescence digitizer and a color film scanner. In addition, the energy responses were measured between 10 and 100 keV. The values were 0.8 for HD-810 above 10 keV and 0.95 at 100 keV for MD-55, which decreased to 0.6 at 30 keV. |
