چکیده انگلیسی


• Preparation and comparison between TP/PVA film and TP/Gelatin gel dosimeters.
• The useful dose range is 0.5–6.5 kGy and from 0.5 to 100 Gy (in case of film and gel dosimeters; respectively).
• The response of unirradiated and irradiated films and gel have a good stability.
• Overall uncertainty of the dosimeter 5.4% at 2σ.

The current work describes the investigation of film and gel samples, which combine poly (vinyl alcohol) (PVA) and gelatin containing thymolphthalein dye (TP). Under the effect of gamma radiation, two different media prepared as a label film and gel dosimeter its color changed from blue to colorless. Results demonstrated that the new detector systems for application in the low and high dose ranges were from 1 to 6.5 kGy in case of film and from 0.5 to 100 Gy as gel. The response of these dosimeters shows excellent post-irradiation stability at different storage time. These dosimeters are independent of the relative humidity at the time of irradiation in the range of relative humidity from 0 to 60%. Uncertainty of this radiation dosimeter was calculated as well as a comparison between two radiation dosimetry systems and suggest their possible application for both low and high dose dosimetry applications in medicine and industry.
