| Summary: | In this study, optical and thermophysical properties of Gafchromic HD-V2 films are investigated. Gafchromic HD-V2 films have been irradiated with electron and photon sources indifferent doses (0–8 Gy). The optical properties of the irradiated films have been examined using an optical scanner and UV–vis spectrophotometer. The thermophysical properties were studied using a photoacoustic spectrophotometer. It is found that the optical density has increased linearly as the dose increases up to 8 Gy. The thermal diffusivity shows similar behavior as the dose increases. An enhancement of 35% is achieved as the dose increases from 0 to 8 Gy from 12 MeV electron beam source.
