Abstract
For decades, film was used as a powerful two-dimensional (2D) dosimetry tool for radiotherapy
treatment verification and quality assurance. Unlike the old silver-halide based radiographic
films, radiochromic films change its color upon irradiation without the need for chemical
development. Radiation dose deposited within a sensitive layer of the radiochromic
film initiates polymerization of the active component, the degree of which depends
on the amount of energy deposited. Response of the film to radiation is commonly expressed
in terms of optical density change, which can be easily measured by any photometric
device. However, a number of factors may have an impact on the signal detected by
the measuring device. This review summarizes technical aspects associated with the
establishment of reference radiochromic film dosimetry and its subsequent use for
either clinical or research applications.
