Over the years, film dosimetry was developed into a powerful 2D high resolution tool for radiotherapy treatment verification and quality assurance. Introduction of the radiochromic film, that has all the advantages of film dosimetry without the need for wet processors, makes this film type a very important dosimetric tool. It has properties equivalent to those of water and has been shown to have a response independent of beam quality in a broad energy range which makes it a suitable candidate for dosimetry in both standard and non standard beams. It is desirable to use the latest EBT-2 GAFCHROMIC(TM) film model in the dosimetry of high dose rate (HDR) Ir-192 sources in water which would provide direct absorbed dose comparison to the current reference dosimetry protocol for brachytherapy (TG-43 and its update). Also, it would be advantageous to perform these dosimetry measurements in a more convenient Solid Water(TM) medium which is less experimentally cumbersome and link the absorbed dose to Solid Water to the absorbed dose to water using a simple correction factor.
