Abstract
New compositions of radio-chromic solutions and polyvinyl alcohol (PVA) films containing different concentrations of Calcein dye have been introduced as high dose dosimeter. The dosimeters were irradiated with gamma rays from C60o source at doses from 5 to 30Â kGy for film and from 0.25 to 1Â kGy for solution. UV/vis spectrophotometry was used to investigate the absorbance (optical density) of unirradiated and irradiated films and solutions in terms of absorbance at 493Â nm for film and 496Â nm for solution. The effects of scan temperature, relative humidity and stability of the response of films and solutions after irradiation were investigated. The results show that these films could be used as dosimeter in industrial radiation processing. The useful dose range of developed Calcein-PVA film and solution dosimeters is in the range of 5-20Â kGy and 0.25-1Â kGy respectively
