Abstract 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 green yellow with exposures gamma rays between 0–80 0–40 kGy, respectively. color response was accelerated chloral hydrate half radiation dose 0–20 kGy for systems, UV–visible spectrophotometer shows outstanding stabilit...
