Radiochromic films (RFs) have been developed for the measurement of the absorbed dose of low-energy photons. RFs are self-developing and radiation sensitive, and the amount of darkening is proportional to the absorbed dose. RFs are easy to handle due

Recently developed radiochromic films can easily be used to measure absorbed doses because they do not need development processing and indicate a density change that depends on the absorbed dose. However, in GAFCHROMIC EBT2 dosimetry (GAF-EBT2) as a
