Comparative study of two mixture dyes based on PVA for industrial use as gamma radiation dosimeter

New film dosimeters PVA/(DCP/CR) and PVA/(DCP/BPR) have been prepared through the casting method. The colorimetric properties of both films changed from violet to pink and from green to yellow with exposures to gamma rays between 0–80 and 0–40 kGy, respectively. The color response was accelerated wi...

Zusammenfassung:New film dosimeters PVA/(DCP/CR) and PVA/(DCP/BPR) have been prepared through the casting method. The colorimetric properties of both films changed from violet to pink and from green to yellow with exposures to gamma rays between 0–80 and 0–40 kGy, respectively. The color response was accelerated with chloral hydrate to half of the radiation dose between 0–40 and 0–20 kGy for both systems, respectively. The UV–visible spectrophotometer shows outstanding stability of the prepared dosimetric systems. Relative humidity was studied and the response indicated that both films possess very good stability during irradiation. Graphical abstract
