Abstract

 Investigation of different preparation techniques related to pH indicator; Neutral Red (NR) dye indicates the effect of the substrate on the dose response. NR was incorporated in poly (vinyl alcohol) (PVA) to prepare a thin film dosimeter and added a gelatine to prepare gelatine gel dosimeter. Upon γ-ray exposure, both systems undergo visual red colour bleaching at 485nm for the film and 480nm for the gel at different rates depending on the sensitivity of each system. These two dosimetry systems depend mainly on the polymer substrate base. The useful dose range was up to 30kGy for thin film and 500Gy for gel form.
