| Popis: | The present study involves a comparison between two dosimetry systems. The first system depends on victoria blue B (incorporating polyvinyl alcohol) as a thin-film dosimeter. The second system depends on the same dye as a liquid dosimeter, which is more sensitive to gamma rays. The prepared film/liquid has a considerable signal that increases upon irradiation and the intensity of the signal decrease with increasing radiation dose. The gamma ray absorbed dose for these dosimeters was found to be up to 25 kGy for the thin film and 700 Gy for the liquid form. Radiation chemical yield, additive substance, dose response function, radiation sensitivity, also before and after-irradiation stability under various conditions were discussed and studied. |
