Abstract
AbstractThree different dosimetry systems were prepared based on diphenyl thiocarbazone (DTH) dye: polymer films made with, poly(vinyl alcohol), DTH liquid dosimeter and DTH gel dosimeter. All the systems received several gamma doses. The three systems were analyzing by UV–Vis spectrophotometery before and after irradiation. The effective dose range in the linear part of these systems is between 1–10 kGy, 0.3–2 kGy, and 50–200 Gy. The dose range of these three dosimeters relies on the concentration of DTH. The radiation chemical yield (G-value) was determined for the three prepared dosimeters, and all three radiation dosimeters were examined before and after irradiation.
