“…These films have a linear response to ionizing radiation over a dose range of approximately 0.1 Mrad to 10 Mrad [22,25,26]. The films also have an equivalent response to x-rays, γ-rays, and electrons from ultraviolet energies up to approximately 1 MeV [27,28,29]. Radiachromic films display a constant response for exposures in air and vacuum, as well as in the presence of ozone [22,23,30].…”
